Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]
Preliminary Reverse-Engineered VPU Driver (CedarX) for AllWinner A10 Plays H.264 Videos
Allwinner framework for their Video Processing Unit (VPU) in their Cortex A8 processors (A10, A13, etc..) is called CedarX. It relies on a binary blob that is working just fine for Android, but not so well for Linux. So several developers started to reverse-engineer CedarX a while back, to fix issues with Linux, and provide an open source driver. Yesterday, they upload a video to show the development progress, and show Big Buck Bunny 1080p H.264 playback using libvdpau-sunxi open source driver with mplayer, and without any binary blobs. The video resize function are not been implemented yet, which is why we can only see the left corner of video, but nevertheless it shows an open source hardware video decoder is on the way. That means once the Lima driver for Mali-400 GPU, and libvdpau-sunxi driver for AllWinner VPU are implemented (which may still take a while), AllWinner A10 SoC […]
ARM Announces Cortex-A12 processor, Mali-T622 GPU and Mali-V500 VPU
Right before Computer 2013, ARM has made a single announcement for 4 new products for smartphones: Cortex A12 core, Mali-T622 GPU, Mali-V500 video processor unit, and POP IP technology. Cortex A12 processor, with 40 percent more performance than Cortex-A9, positions itself between Cortex A9 and A15 offerings, and brings virtualization, big.LITTLE processing, and up to 1TB addressable memory to mid-range devices. Combined with the new Mali-T622 GPU, it will offer GPU Compute and OpenGL 3.0 solution. Add the new Mali-V500 video IP solution to complete the SoC for tomorrow’s, 2015 more exactly, mid-range smartphones and tablets between $200 and $350. Cortex A12 will have the following key features: Architecture – ARMv7-A Cortex Multicore – 1-4X SMP within a single processor cluster Multiple coherent processor clusters through AMBA 4 technology Support ARM Thumb-2 TrustZone security technology NEON Advanced SIMD DSP & SIMD extensions VFPv4 Floating point Hardware virtualization support Large Physical […]
FXI Technologies Cotton Candy HDMI Stick To Fully Support Both Android and Ubuntu
FXI Technologies was the first company to ever show an HDMI TV dongle when they unveiled the Cotton Candy in November 2011. Since then, many Chinese companies started to provide similar products at lower cost, and the company further improved the Cotton Candy, which is still powered by Exynos 4210 (dual core Cortex A9), by making it even smaller, and getting rid of the internal flash in the process. As a memory refresher, here are the specifications of the Cotton Candy: SoC – Samsung Exynos 4210 dual core Cortex A9 + Mali-400MP4 System Memory – 1GB DRAM Storage – No flash, up to 64GB microSD Video Output – HDMI Connectibity Wifi 802.11b/g/n Bluetooth 2.1 + EDR USB – USB 2.0 male connector for power and connection to devices that supports USB mass storage + microUSB Video Codecs- 480p/720p/1080p Decode of MPEG4-SP/H.263/H.264 AVC/MPEG-2/VC1 Audio Codecs – MP3, AAC, AAC+, Real Audio […]
Ubuntu 11.10 on GK802/Hi802 mini PC with 2D/3D and Video Hardware Acceleration
You may remember an Ubuntu 11.10 image was released via Geekbuying early January, but this image would not boot on my Hi802, lacked 2D/3D acceleration, and to my knowledge there hasn’t been any update since then. So hope of proper Linux support on the device was fading, until the community discovered Freescale released patches for i.mx6 HDMI dongles, developers setup the imx6-dongle community, and after a lot of work, mainly by three members: Jasbir, Dmitriy (rz2k) and James, there’s now GPU and VPU support on Ubuntu 11.10. Here’s a summary of the current status: Wifi working. External SD working Matched IOMUX configuration to align with the Android image. Stripped out unnecessary device initialisation from the original HDMI dongle source. Enabled EGL and GLES HW Acceleration in Ubuntu. Unity desktop might be partially HW accelerated (TBC) Jasbir uploaded a video to YouTube to show the progress, and it looks pretty good. […]
