Renesas R-Car H2 is an Octo Core big.LITTLE Processor for Your Car

Renesas announced a new automotive SoC called the R-Car H2 that features 4 Cortex-A15 cores together with 4 Cortex A7 cores (optional) in big.LITTLE configuration, as well as an Imagination PowerVR Series6 G6400 GPU. This SoC can optionally come with Renesas SH-4A, a real-time processing CPU core acting as a multimedia engine (MME) , and Renesas’ IMP-X4 core, a real-time image processing unit that enables developers to implement augmented reality application such as 360-degree camera views and image recognition. This Renesas processor is a multimedia power house, as it can handle 4x 1080p video en/decoding, including Blu-Ray support at 60 frames per second, as well as image/voice recognition and high-resolution 3D graphics with virtually no CPU usage. Here are R-Car H2’s specifications provided on Renesas website: Product number R8A7790x Power supply voltage 3.3/1.8 V (IO), 1.5/1.35 V (DDR3), 1.0 V (Core) CPU core ARM Cortex-A15 Quad ARM Cortex-A7 Quad (device […]

OpenELEC 3.0.0 on Raspberry Pi – Installation and Video Tests

Yesterday, OpenELEC developers announced the release of OpenELEC 3.0.0, a lightweight OS running XBMC Frodo 12.1 for several platforms including the Raspberry Pi (OpenELEC stands for Open Embedded Linux Entertainment Center). When the Raspberry Pi was initially released, I did not feel like testing it as a media center, mainly because of codecs limitations. But over time, this has improved with the availability of MPEG-2 and VC-1 codecs (for a fee), and GPU accelerated support for free codecs such as VP6 and VP8, so today I’ve tested to give a try and install OpenELEC 3.0.0 on my Raspberry Pi. I’ll first give installation instructions, then test several types of videos container formats, and video / audio codecs, as well as give some quick impression about the performance and stability of OpenELEC on this low cost board. Installing OpenELEC on Raspberry Pi To install OpenELEC, I basically followed the instructions provided […]

Zealz GK802 Is (Temporary?) Available for $69.99 on GeekBuying

Zealz GK802 is a mini PC based on Freescale i.MX6 Quad processor, with 1GB RAM, 8 to 16 GB internal memory (internal micro SD card). The main selling points of this HDMI dongle is that it’s the only currently available quad core processor (about to change), it’s hackable and unbrickable with easy access to the serial console, full support for Linux with hardware video decoding and 2D/3D acceleration (work in progress), and Freescale has released proper software and hardware development resources for the i.MX6 processor. As mentioned in my review of Hi802 mini PC, the downside is that Vivante GC2000 GPU performance is lower than the Mali-400 MP4 found in Rockchip RK3066 mini PC, and its price (usually above $90) is about double the price of Rockchip RK3066 mini PCs. We can’t do anything for Vivante GC2000 performance, but Roman found a coupon code “FVKIWVAG” on a Russian forum that […]

Ubuntu 11.10 Image for Hi802 / GK802 is Now Available for Download

About 2 weeks ago, Jasbir released an Ubuntu 11.10 image and installation instructions for GK802 and Hi802 mini PCs based on Freescale i.MX6. I could only find time to give it try yesterday and today. I’ll provide the steps I followed to install the image, and my quick first impressions of the stability and performance of this image. Installation Instructions I mainly followed the instructions provided by Jasbir, and run GParted to increased the partition size on my micro SD card. The image is for a 8 GB micro SD, but those instructions should work on 4GB SD card and greater, as the rootfs partition is only 3GB large. Download the Ubuntu 11.10 image, uboot, as well as the kernel image and modules in a Linux PC:

wget http://dl.miniand.com/jas-hacks/gk802/ubuntu_gk802.img.gz
wget http://dl.miniand.com/jas-hacks/gk802/u-boot.imx
wget http://dl.miniand.com/jas-hacks/gk802/uImage_3.0.35-0269_cpu_freq
wget http://dl.miniand.com/jas-hacks/gk802/modules_3.0.35-02695.tar

wget http://dl.miniand.com/jas-hacks/gk802/ubuntu_gk802.img.gz

wget http://dl.miniand.com/jas-hacks/gk802/u-boot.imx

wget http://dl.miniand.com/jas-hacks/gk802/modules_3.0.35-02695.tar

Copy the image, uboot and the kernel to the micro SD card by typing the commands below:

gzip -d ubuntu_gk802.img.gz
sudo dd if=ubuntu_gk802.img of=/dev/&lt;sd_device&gt;
sudo dd if=u-boot.imx bs=1k seek=1 of=/dev/&lt;sd_device&gt; &amp;&amp; sync
sudo dd if=uImage_3.0.35-0269_cpu_freq of=/dev/&lt;sd_drive&gt; bs=1048576 seek=1 &amp;&amp; sudo sync

Nvidia Updates its Tegra Roadmap with Parker 64-Bit ARM SoC, Unveils Kayla CUDA Development Platform

Nvidia has given an update about the roadmap for its Tegra processor at the GPU Technology Conference in San Jose, California. Tegra 4 will still be followed by Logan (Tegra 5) as planned with a Kepler GPU and support for CUDA and OpenGL 4.3, but “Stark” has been replaced by “Parker” (Tegra 6) which will be the first 64-Bit Tegra processor based on Denver CPU, Maxwell GPU and make use of Finfet transistors. Logan will be available in 2014, and Parker should be available in 2015 with 100 times more performance than Tegra 2. With this kind of performance, the separation line between desktop and mobile processors will be gone. Nvidia also unveiled Kayla (“Logan’s girlfriend”), a development platform for CUDA and OpenGL based on Tegra 3 quad-core ARM processor and a Kepler GPU connected via a PCI express slot. Jen-Hsun Huang (above) showcased Kayla performance by running real-time ray […]
