Lumia 1020 King of Camera phones ?

Nokia has a long tradition of packing tremendous cameras with great quality in their phones for example The N95,N8,808 Pureview etc.





The Nokia Lumia 808 Pureview and Nokia N82 with CarlZeis optics.








Now The Nokia Lumia 1020 a windows mobile phone with whopping 42 Megapixel camera took the baton from it's fore runners.

Not only the megapixel count that is special also the Shutter speed the ISO levels and Optical image Stabilization will give you the best shot night or day.Forgot to mention the Expert shot that let you shoot two pictures with different resolution at the same time.
Also it has two high quality mics that let you record stereo sound with deep bass ha ha.....Never heard of that in a mobile it will be possible.Also to my astonishment that the new phone in spite of the bigger image sensor and added features is nearly 30 grams lighter than it's predecessor and also 2 millimeters thinner let alone the bulge at camera.
Also the lens are CarlZeis which are better than Exmor R in my opinion.
The Image processing unit is unknown but I think it will be Broadcom's.
Main Specifications are as follows

Processor - Krait

Ram  -  2 Gigs
Chip set - Snapdragon S4
GPU -  Adreno 320
Camera - 42MP
Battery - 2000Mah replaceable
Front Cam - 1.3 MP wide angle
Sensors - Gyro,Magneto,Accelerometer,Barometer,Ambient Light,Proximity sensors
Card slot - Yes upto 64 Gigs
Flash ROM-16,32 Gigs.

It also comes with NFC and Barometer.Wireless charging is an Option with additional back-cover.Nokia also released a camera cover with extra 1050Mah battery for extra grip and Juice.

This phone is a must buy for Those who use their phones camera as their sole camera.


Mediatek MT6592 Octocore Chipset


 Mediatek a fab-less mobile chipset manufacturer known for cheap Dual and Quad core solutions is on its way of producing an Octocore mobile chipset MT6592
     Well in fact it's not quite that Octocore that you might imagine but it's a Quadcore chipset based on ARM's  "little--Big" computing.This Beastly chipset features four Cortex a15cores and four Cortex a7 cores only max four of these cores will run at a time Cortex a15 will take over when running powerful tasks like playing a HD video or a game and leave the miniscule tasks to Cortex a7 thus saving power and giving the best performance both at a time.
      
           Note-Anew update states that all 8 cores will be 2.0ghz Cortex a7's and it will be a real 8 core chipset and not a pseudo one.

     This shows that how Android paved a way for some nameless and fab-less manufacturers to establish themselves and to compete with other big companies.
     The rumors are that Huewai and Sony are deciding to launch their new Android phones based on this Chipset.

Currently in the market are Exynos Octa chips made by Samsung.......Yeah those used in international variant of Galaxy s4.

Some expected features from the MT6592.
  --2.0ghz cortex A7 cores
  --8 core chipset
  --power vr based graphics (but not some as exynos octa which has 3 PowerVR sgx 544 cores clocked some where at 533mhz)

Where is this mobile revolution taking us -A journey through past and into the future

Five years ago almost 70% of people now using smartphone never used one.Also most of those used them don't know what their phones capable of and even the never visited app stores or never downloaded any apps.Then it was word of Symbian and Windows mobile some used Blackberry and Palm.










                                                        then these two were leaders


Now five years after there is a huge explosion in the rate of smartphone usage first reason cheaper prices and widely available mobile operating system Android.Either small and big cellphone manufacturers can use android for free so they can't very much differentiate themselves in terms of software but they can do in hardware the firms that can adapt to changes they succeeded(Samsung) and those who are just reluctant failed(Nokia). Even five years ago mobile operating systems were widely available like Symbian and Windows mobile but there is lot of fragmentation(Much greater than android) also the smartphone manufacturers has to invest in software to customize the operating systems for their mobiles.So the small manufacturers and start ups can't invest that much because it will rise the cost of phone or they can't afford to do so.



   But with the advent of android everything has changed there has been a single app store for all manufacturers owned and managed by Google.Manufacturers need not invest in developing all API's and SD K's Google does that on behalf of them.Even they need not pay any license fees to Google.In short they are getting a world class operating system to use on their phones for free.
 

 

                          These small chipset vendors changed the face of smartphone revolution
   Now come to the hardware part then there weren't that much companies involved in mobile chip-set business now the scene has changed there are many companies that are producing chip-sets and they also give all the driver support to the manufacturers.Then it was only Texas instruments and Samsung that has the capability to produce mobile chip sets at large due to the cost involved.Now the price of silicon has fallen many folds.A few years ago the phone that would have costed some 800 bucks now only costs around 100bucks.

Now what is the future and which way is this mobile revolution going along.....................

  Now the future is wearable tech and multipurpose devices people just don't want to put tech in their pockets the want tech to be part of them the Google glass and iwatch are from those category.Even the just start as complementary items for Smart phones they soon take over.
  Now the question is what happens to these small manufacturers in the advent of wearable tech,this kind of tech will bring in lot of patents which surely big manufacturers will own and it will be a havoc to small manufactures and it may lead to monopolistic competition.
   Also we don't want to carry different items for different tasks we want both PC and Mobile phone to unite some call it Phablets but no they are not.
     A device should function as a phone when we use it and should be a full fledged PC when you dock it and you should be able to connect all kinds of peripherals to it like your PC.

     Ubuntu mobile is one such example but it is too far from reality.
But anyway this is going to be the future.

     Please give your comments......

Apple iwatch

This is the time to talk about iwatch.
                    At this year end a new i device is getting added to Apple's "i" catalog., much more interesting is the rising competition amongst tech giants in wearable technology.Along with Google's long known Google glass Samsung has announced that they are in making of a smart watch,the competition is rising."Also Tim Cook's comment that "hand is the best place for wearable tech than head" say's apple's intentions on iwatch.

Any way competition is so intense also notable thing here is Samsung's bendable youm display this kind of display is more realistic for wearable tech which should be hard enough for daily usage.

                                                  iwatch concept Courtesy -Technobuffaloe

So now let's get on to what we can expect from iwatch.

 Is the screen bendable..... We want to have bendable screens in our watches they are stronger than normal screens they can resist scratches with out any gorilla glass thing which I don't like.And they are really bendable which is so exciting.Also for a watch clearly amoled is the winner if you want color screens which consumes less battery which is so important for a watch.
 Sensor's........................................ These are the real things that makes a smart watch so smart so,what we can expect a GPS , Gyro , Accelerometer , Magnetometer what else may be a sensor to calculate the circumference of wrist so it cam adjust the screen along.May be a Heartbeat sensor and thermometer there is a possibility for a humidity sensor too.
 Applications.............................. Is the watch smart by it self or is just dumb enough only to push notifications from a mobile phone.Does it have it own applications or it just mirrors the mobile phone's display.Any way mirroring requires WiFi or Bluetooth which drinks all the juice in just a few hours.
 Water and dust proof......... It should be at least water proof for up to 30 meters i cant call something a watch if it isn't water proof .There are many watches available for a few bucks that are waterproof iwatch would surely cost few hundred bucks waterproof will be the least expected feature from it.
 Battery life.................................You just can't call something a watch if it can't last for at least a month customers don't want to charge their watch daily.Searching for a charging point to charge your watch is just so stupid.

Let us think realistically what we can do on a smart watch.

We can see time.....................................................Check

We can see missed calls..........................................Check

 See messages..........................................................Check

Write messages........................................................May be not

Dictate messages.....................................................Yes

Check heartbeat......................................................Check

Check temperature..................................................Check

Record voice ..........................................................Check

Camera & Video......................................................I am not James bond

Mini missiles.............................................................I am not James bond

Park and Retrieve car...............................................May be yes

Place a call...............................................................Looks awkward but I am ready to accept change.

Holographic content..................................................It's future but reserve it to Hollywood for now.



But I believe that something that is a duo of watch and a smart phone is the future.

         Some thing that looks like slap band
     

         A phone you can use and slap it to wrist like a slap band is truly the future.


Please comment what you want from a smart watch.

Tegra 4 Nvidia's next step into mobile gaming Industry

Nvidia recently unveiled their new SOC Tegra 4.

Though it may not look as powerful as the Qualcomm's counterpart the Snapdragon 800,this chip is aiming at the android gaming market niche that Nvidia wants to penetrate.The announcement of project shield and other handheld consoles running android shows how big gaming on android platform will going to be.
                                      .................Now a long story short...............
This will be a tough time for Sony's PS vita whose sales still not gained momentum neither it caught developer's interest.But Nintendo is in a safer position by differentiating themselves from android handhelds by adding 3d tricks to games.Also more developers are interested in developing for 3ds rather than PS vita and 3ds already have sufficient titles to impress beginners and veterans.
   
                             all that beautiful hardware put to waste will be a nightmare for any gaming lover

 So what is the lesson learnt.............!
              It's not about how powerful the hardware platform is but it is about how good you put it into use(and it's good time to mention how iPhone is different from android phones Apple is always good at marrying great hardware with insanely great software).
Nvidia is so good in this respect they gathered some good developers and make them develope games with additional effects that make use of tegra's GPU right from the beginning when it launched tegra2 now it got some respectable titles to differentiate itself from other ARM SOC makers.(also this is both good and bad good for gamers bad for android(cause fragmentation)
        
          Now it's tegra4's turn to push it much further.Also do not forget that all tegra2 and tegra3 games are backward compatible with tegra4 SOC.Benchmarks may show that Tegra4 is less powerful than it's counterparts but it's relative value is much more which will be the ultimate factor.


Let us wait time will decide who will rule the billion dollar gaming market.

Comparing various GPU solutions Power VR,Mali,Ge force mobile,Adreno,Vivante.

          You need a good CPU to process your data real fast and to perform faster calculations .But these days GPU is becoming more and more important due to the advent of visual computing..To smoothly run all the eye candy and eye popping graphics in our mobile phones it requires really good GPU also to play Console quality games in your mobile devices you really need a GPU that screams.

                               Apple SOC uses an ARM CPU and Imagination technologies Power VR GPU

  Here I am comparing all 5 main stream GPU solutions for Mobile SOC's some of these are proprietary (Adreno and Ge force mobile)and some of them allow many licensed OEM's to use them.

GPU introduction----------------------
     
   Power VR           - Imagination technologies (OEM)
   Mali                    -  ARM
   ULP Geforce      - Nvidia 
   Adreno               - Qualcomm
   Vivante               - Vivante Corp

Of these GPU's four of them (Power VR,Mali,Adreno,Vivante) use tile based rendering.
  
          So what is tile based rendering? Why is it useful?
             Most desktop GPU's use brute raw power to render games and pictures and all the graphics you see but in the mobile scenario the GPU should be power efficient and shouldn't burn your pockets by getting too hot.So the tile based rendering this type of rendering divides the screen that you van currently see into small tiles and renders them independently all those scenes which the user cannot see are not rendered so this speeds ups the rendering and saves a lot of power but NVIDIA also goes a step more and separated the GPU in unlike blocks, only the presently utilized areas are also rendered, shutdown the other areas, only the pixel shader needs the vertex shader is shut down, and vice-versa.

So now I will compare all the latest solutions from each vendor.
 1.Power VR - For Power VR GPU's performance scales symmetrically with every increase in core count and multiples of clock speed thanks to tile based deferred rendering which is unique to this GPU.
   foe example let us consider PowerVR SGX 543Mp@ 300mhz its triangle fill rate is 70million triangles per second then Power VR SGX543Mp2 and Power VR SGX 543Mp2 will have same fill rate of 70mt/s
2.ULP Geforce - These chips are multi cored scaled up to 72 cores  but core count doesn't mean better performance.But these chips can process Physx,Smoke,fog,reflection and lighting effects better than other chips so they tend to be better at gaming.Looking like Nvidia is looking at that market Niche
3.Mali - For now until the release of rogue by Imagetec the Mali t6xx series will be crowned the most powerful mobile gpu for its power to drive insane screen resolutions at nearly 60fps.
4.Adreno - Adreno is formerly imageon GPU's that has been sold by AMD to Qualcomm this is one insanely powerful single core solution this GPU's tends to run cooler than rest of competition even under heavy load.

How to flash all Mediatek Phones..All china phones ,Micromax,Celkon and Karbonn phones.

Here I am gonna show you how to flash all Mediatek Phones(all Mtk65xx series). By this method you can flash many of Celkon phones Micromax Phones and Karbonn phones Actually Most of Celkon,Micromax,Karbonn phones are re branded Alps company phones that are made in china.I came to know that many people are facing difficulty in flashing Mediatek phones especially when installing USB Vcom drivers.
      
    Here I am gonna explain you step by step. ...........Let's start.

Step 1.....Buddies -Installing Drivers
                   Here is the link
Download from the above link and extract .


  1. Switch off your phone and connect it to your computer.
  2. Now windows will ask to install drivers automatically or manually select manually find the driver and install .Now show windows the downloaded driver and install it
  3. If you have correctly installed your driver you should probably see you phone in device manager but only for a few seconds.I don't know why but it disappears after few seconds after you connect your phone.       
 Step 2.....Buddies - Downloading SP flash(smartphone flash) tool of latest version possible(Latest the version lesser the bugs) Here's the link
         Now let's move onto step 3
 Step 3.....Buddies - Download required ROM files and scatter file depending on your phone Model.
 Step 4.....Buddies - Now open flash tool Remove your phone if connected switch it off if it is on remove any Sim cards and memory card if present(this may not be required but we want do the flashing clean so do it).
        Do not connect your phone to PC not now not yet.Open flash tool and select the scatter file now press F9 or Click download the check sum verify process will start after the process ends connect your phone do not connect you phone when check sum verify process is still going on (that is after pink progress bar hits 100%). If you don't have any check sum files to verify then you can connect your phone immediately after you hit download or F9.
  
 

 After you connect your phone a red progress bar starts then violet then yellow then green and finally a dialog box with green circle will appear indicating flashing is successful.
   If you Don't get it first time keep trying,just follow the steps.

If you want to flash only few files-You should be careful when flashing few files there is a High risk of bricking your phone by doing so.
  Select the files you want and click download the click yes to the dialog box and you are done if a green box appears.

    

What is Check sums ? you may ask
      These are files that verify the integrity of ROM that you are flashing it verifies whether your ROM is corrupted during download or due to file system errors. So your phone won't get bricked.

Exynos vs Allwinner vs Mediatek vs Rockchip vs Action vs Tegra vs Freescale

                          Quadcore Battle


Today I am going to compare the performance of these  chipsets by pitting them against each other.

Basic introduction .

Exynos4412  by Samsung uses 4 cortex a9 cores and features Mali 400mp4 quad-core gpu by arm.
Tegra3 by Nvidia features 4 cortex a9 cores and 12 core ultra low power geforce GPU.
Alwinner a31 by all-winner technology China features 4 cortex a7 cores and dual core power vr sgx544mp GPU.
Mediatek MTK series chipsets by Mediatec inc China features quad-core cortex a7 CPU and a quad-core overclocked Power vr sgx544mp GPU.
Actions ATM7029 by actions semiconductors featuring quadcore cortex a5 and vivante GC1000 GPU.
Rockchip RK3188 by Rockchip semiconductors China featuring quadcore cortex a9 cpu and quad core overclocked mali300mp4 GPU.
Freescale imx6Quad by Freescale featuring quadcore cortex a9 CPU and vivante GC2000 GPU.


Comparison: Cortex-A7 and Cortex-A9

In 2011, Cortex-A7 was introduced by ARM, and that is four years after Cortex-A9. When compared with Cortex-A9, Cortex-A7 design does have some improvements, as listed on ARM official website:
  • Lower L2 latencies (10 cycles)
  • Improved OS support for L2 maintenance due to simplified software control
  • Designed with a low power approach
  • Improved branch prediction
  • Improved memory system performance
  • 64b Load Store path, improves integer and NEON performance
  • 128b AMBA 4 buses improve bandwidth
  • Increased TLB size (256 entry, up from 128 entry for Cortex-A9 and Cortex A5)
  • Increased performance for large workloads like web browsing
  • Seamlessly compatible with Cortex-A15 (big.LITTLE)
In ARM Cortex-A7, ARM transforms its design principle from improving the system performance by increasing frequency, to MPCore architecture that could bring improvements in performance, and at the same time, optimize the high power consumption and heat caused by high frequency of Cortex-A9.

If you want to buy a cheap quadcore tablet I recommend Exynos or rockchip but not Alwinner. Though Alwinner has a better GPU performance it's cpu performance is pretty weak due to low clock-speed also its 40nm manufacturing process contributes to weak performance.





TI OMAP

OMAP (Open Multimedia Applications Platform) image/video processors developed by Texas Instruments are a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications. OMAP devices generally include a general-purpose ARM architecture processor core plus one or more specialized co-processors. Earlier OMAP variants commonly featured a variant of the Texas Instruments TMS320 series digital signal processor.

On Sept 26 2012 Texas Instruments announced that they are going to wound up the production of OMAP chipsets and they are going to focus on embedded platforms.So the fate of OMAP 5 is unknown .

There are basically 5 series of OMAP chipsets from OMAP 1 to OMAP 5. Many of Nokia Symbian smartphones are powered by OMAP chipset including N95,N96,N97 and some communicator series phones.Also many android phones are powered by 3rd,and 4rth generation chipsets.Also N900 and N9 use OMAP 3 chipsets.

OMAP chips use a ARM processor and Imagetecs  Power vr gpu integrated on the chip.

OMAP 1

The OMAP 1 family started with a TI-enhanced ARM core, and then changed to a standard ARM926 core. It included many variants, most easily distinguished according to manufacturing technology (130 nm except for the OMAP171x series), CPU, peripheral set, and distribution channel (direct to large handset vendors, or through catalog-based distributors). In March 2009, the OMAP1710 family chips are still available to handset vendors.
Products using OMAP 1 processors include hundreds of cell phone models, and the Nokia 770 Internet tablets.
  • OMAP171x - 220 MHz ARM926EJ-S + C55x DSP, low-voltage 90 nm technology
  • OMAP162x - 204 MHz ARM926EJ-S + C55x DSP + 2 MB internal SRAM, 130 nm technology
  • OMAP5912 - catalog availability version of OMAP1621 (or OMAP1611b in older versions)
  • OMAP161x - 204 MHz ARM926EJ-S + C55x DSP, 130 nm technology
  • OMAP1510 - 168 MHz ARM925T (TI-enhanced) + C55x DSP
  • OMAP5910 - catalog availability version of OMAP 1510

OMAP 2

These parts were only marketed to handset vendors. Products using these include both Internet tablets and mobile phones:
  • OMAP2431 - 330 MHz ARM1136 + 220 MHz C64x DSP
  • OMAP2430 - 330 MHz ARM1136 + 220 MHz C64x DSP + PowerVR MBX lite GPU
  • OMAP2420 - 330 MHz ARM1136 + 220 MHz C55x DSP + PowerVR MBX GPU

OMAP 3

The 3rd generation OMAP, the OMAP 3 is broken into 3 distinct groups: the OMAP34x, the OMAP35x, and the OMAP36x. OMAP34x and OMAP36x are distributed directly to large handset (such as cell phone) manufacturers. OMAP35x is a variant of OMAP34x intended for catalog distribution channels. The OMAP36x is a 45 nm version of the 65 nm OMAP34x with higher clock speed.
The video technology in the higher end OMAP 3 parts is derived in part from the DaVinci product line, which first packaged higher end C64x+ DSPs and image processing controllers with ARM9 processors last seen in the older OMAP 1 generation or ARM Cortex-A8.
Not highlighted in the list below is that each OMAP 3 SoC has an "Image, Video, Audio" (IVA2) accelerator. These units do not all have the same capabilities. Most devices support 12 megapixel camera images, though some support 5 or 3 megapixels. Some support HD imaging.

OMAP 4

The 4th generation OMAPs, OMAP 4430, 4460 (formerly named 4440), and 4470 all use dual-core ARM Cortex-A9 and two ARM Cortex-M3 cores. The 4430 and 4460 use a PowerVR SGX540 integrated 3D graphics accelerator, runnning at a clock frequency of 304 and 384 MHz respectively.4470 has a PowerVR SGX544 GPU that supports DirectX 9 which enables it for use in Windows 8 as well as a dedicated 2D graphics core for increased power efficiency up to 50-90%%]All OMAP 4 come with an IVA3 multimedia hardware accelerator with a programmable DSP that enables 1080p Full HD and multi-standard video encode/decode. OMAP 4 uses ARM-Cortex A9s with ARM's SIMD engine (Media Processing Engine, aka NEON) which may have a significant performance advantage in some cases over Nvidia Tegra 2's Cortex-A9s with non-vector floating point units. It also uses a dual-channel LPDDR2 memory controller compared to Nvidia Tegra 2's single-channel memory controller.

OMAP 5

The 5th generation OMAP, OMAP 5 SoC uses a dual-core ARM Cortex-A15 CPU with two additional Cortex-M4 cores to offload the A15s in less computationally intensive tasks to increase power efficiency, two PowerVR SGX544MP graphics cores and a dedicated TI 2D BitBlt graphics accelerator, a multi-pipe display sub-system and a signal processor.They respectively support 24 and 20 megapixel cameras for front and rear 3D HD video recording. The chip also supports up to 8 GB of dual channel LPDDR2/DDR3 memory, output to four HD 3D displays and 3D HDMI 1.4 video output. OMAP 5 also includes three USB 2.0 ports, one USB 3.0 OTG port and a SATA 2.0 controller.
