Intel Takes on ARM with Silvermont Microarchitecture for Low Power SoCs

Intel has launched Silvermont, a new microarchitecture for low power SoC targeting smartphones, tablets, and servers in data centers. Silvermont SoC will be manufactured using 22nm Tri-Gate SoC process, and the company claims 3x times more peak performance than current generation Atom processors, or 5 times less power consumption at the same performance level. Silvermont will be used in Bay Trail, Avoton, and Merrifield processors: Intel’s quad-core “Bay Trail” SoC is scheduled for Q4 2013 tablets, and variants of the “Bay Trail” platform will also be used in market segments including entry laptop and desktop computers. Intel’s “Merrifield” is scheduled to ship to customers by the end of this year, and actual smartphones will show up in 2014. Intel’s “Avoton” will be used in low power microservers, and provide full server product capability that customers require including 64-bit, integrated fabric, error code correction, Intel virtualization technologies and software compatibility. Intel […]

Vivante GC4000 is The Best Mobile GPU… When It Comes to Accuracy

Most of the time, mobile GPU comparisons involve benchmarks such as Antutu, Nenamark 2, etc…, or people may consider which games will be able to run smoothly with a particular device, but we seldom compare image quality, for the simple reason it’s usually more difficult to achieve. YOUi Labs has just done that, however, by running the shader code below on several hardware platforms, mainly Android tablets, with the most common mobile GPUs, and used the results obtained with a Desktop PC GPU, Nvidia Geforce GT 630M, has a reference.

precision highp float;
uniform vec2 resolution;
void main( void )
{
      float x = ( 1.0 – ( gl_FragCoord.x / resolution.x ));

      float y = ( gl_FragCoord.y / resolution.y ) * 26.0;
      float yp = pow( 2.0, floor(y) );
      float fade = fract( yp + fract(x) );
      if(fract(y) &lt; 0.9)
          gl_FragColor = vec4( vec3( fade ), 1.0 );
    else
          gl_FragColor = vec4( 0.0 );
}

precision highp float;

uniform vec2 resolution;

void main( void )

{

float x = ( 1.0 – ( gl_FragCoord.x / resolution.x ));

float y = ( gl_FragCoord.y / resolution.y ) * 26.0;

float yp = pow( 2.0, floor(y) );

float fade = fract( yp + fract(x) );

if(fract(y) < 0.9)

gl_FragColor = vec4( vec3( fade ), 1.0 );

else

gl_FragColor = vec4( 0.0 );

}

Here are the results: The worst GPUs are Mali-400 MP4 in Exynos 4412 and Geforce ULP in Tegra 3, which can respectively only show 5 and 8 lines before degradation, and the top two GPUs are Qualcomm Adreno 225 in MSM8660A, and Vivante GC4000 in HiSilicon K3V2 processor. Imagination Technologies SGX544 and ARM Mali-T604 also provide decent results, but […]

Linaro Releases IKS big.LITTLE Implementation Source Code

Yesterday, Linaro announced the released of the IKS (In-kernel switcher) implementation for big.LITTLE processor which allows the SoC to switch between individual Cortex A7 or Cortex A15 cores to optimize power consumption. Currently, the only consumer device using supporting big.LITTLE the Samsung Galaxy S4 thanks to Samsung Exynos 5 Octa featuring 4 ARM Cortex A7 and 4 ARM Cortex A15 cores. IKS implementation can only make use of 4 cores at a time in this processor, since it must choose between A7 or A15 depending on the load. HMP (Heteregenous Multi-Processing) implementation is currently worked on in order to be able to use all 8 cores, and distributes tasks to the right core for the job. You can read my previous post for differences between IKS and HMP. Linaro explains the current source still needs a few more modifications before being upstream to mainline. The code was developed for and […]

Promate LumiTab Android Tablet Features a DLP Pico-Projector

Back in 2011 & 2012, we saw some Android products with a pico-projector, including a lightbulb running Android, but pico-projectors never really seemed to be embedded into consumers products. Promate, however, decided to add one of those to one of their Android tablets. Promate Lumitab would just be a typical Android 4.2 tablet with a 7″ touchscreen, a dual core processor (OMAP4460), 1GB RAM, 16GB flash, if it did not also come with a DLP pico-projector capable of outputting an image up to 100″ (254 cm). Promate Lumitab Specifications: SoC – TI OMAP4460 Dual-core ARM Cortex-A9 @ 1.5GHz + PowerVR SGX540 GPU System Memory – 1GB LPDDRII RAM Storage – 16GB flash, and a microSD slot Display – 7-inch IPS display (1024×600) Video Output mini HDMI Pico-projector DLP technology 854×480 (WVGA) resolution. 35 Lumens, Projection size of more than 100 inches, and projection ratioof 1.5 Audio I/O – 3.5mm stereo […]
