Amlogic S912 Processor Specifications

Amlogic plans to launch at least three new processors for OTT boxes and set-top boxes this year: Amlogic S905X, Amlogic S912, and Amlogic S905D. We already knew Amlogic S905 specifications, but I’ve recently received a document with some more details about Amlogic S912 revealing Mali-T820 GPU, a lack of USB 3.0 support, but still some interesting features such as HDMI 2.0a, 4K VP9, 10-bit H.265, Gigabit Ethernet Mac, and so on. Amlogic S912 specifications with highlights in bold showing differences with Amlogic S905X: CPU Sub-system – Octa core ARM Cortex-A53 CPU up to 2 GHz (DVFS) with two CPU clusters one optimized for high performance (big) and the other for low power (LITTLE) 3D Graphics Processing Unit –ARM Mali-T820MP3 GPU up to 750MHz (DVFS) with 3 shader engines supporting OpenGL ES 1.1/2.03.1, DirectX 11 FL9_3, OpenCL 1.1/1.2 full profile and RenderScript. 2.5D Graphics Processor – Fast bitblt engine with dual […]

Rockchip PX3 and PX4 Processors Are Designed for Automotive Infotainment & Dashboards

Rockchip PX2 processor, similar to Rockchip RK3066 but targeting industrial and automotive applications, was launched in 2014. Rockchip now has at least two new member in their PX family with PX3 and PX4 specifically designed for automotive infotainment and car dashboards thanks to dual display support, at least according to one article on Elezine. Rockchip PX3 is definitely confirmed with its own page on Rockchip website, and features a quad core Cortex A9 @ 1.4 GHz with a Mali-400MP4 GPU, and while there’s no info about PX4 yet on the company website, the SoC should come with a quad core Cortex A53 processor @ 1.3 GHz with a Mali-T722 GPU, as well as HDMI 2.0 video output, and H.265 video decoding. The article also lists 7 key function of Rockchip solutions: “Quick startup and fast revert track” Navigation system with free updates HD video recording (car DVR) Advanced ADAS algorithm […]

Telechips TCC898x (Alligator) 64-bit ARM SoC is Designed for High-end 4K Set-Top Boxes

Telechips processors were often found in consumer devices such as Android tablets, mini PCs and TV Sticks a few years ago, but it’s been a while since I have seen a devices based on Telechips. So after seeing an automotive SoC from the company, I decided to visit the company website to check if they were still designing processors for the consumer market, and found TCC898x quad core Cortex A53 processor for “Smart Stick, IP-Client and STB with 4K 60fps decoding” with some interesting features. Telechips TCC898x SoC specifications: CPU- Quad core Cortex A53 processor with NEON, TrustZone, 32KB/32KB L1 cache and 512KB L2 cache MCU – Cortex-M4 micro-controller GPU 2D – Vivante GC420 composition processing core for 4K user interfaces 3D – ARM Mali-400MP2 VPU – Multi-format VPU and 4K VPU with HEVC and VP9 support Memory I/F – DDR3/4 Storage I/F – NAND controller (60-bit ECC), SD/eMMC controller […]

Linux 4.5 Released – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.5 on Sunday: So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,but it could have gone either way. We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual. And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has […]

64-bit ARM (Aarch64) Instructions Boost Performance by 15 to 30% Compared to 32-bit ARM (Aarch32) Instructions

Yesterday was quite an eventful day with the launch of two low cost 64-bit ARM development boards, namely Raspberry Pi 3 and ODROID-C2, and as usual there were some pretty interesting discussions related to the launch of the boards in the comments section. One of the subject that came is that while Raspberry Pi 3 board is using a 64-bit processor, the operating systems are still compiled with 32-bit instructions (Aarch32) and even optimized for ARMv6, and they intend to keep it that way according to Eben Upton interview: Eben readily admits that not all the capabilities of the new parts are going to be used at launch, however. “Although it is a 64‑bit core, we’re using it as just a faster 32-bit core,” he reveals about the Pi 3’s central processing unit. “I can imagine there’d be some real benefits [to 64-bit code]. The downside is that you do […]

ODROID-C2 64-Bit ARM Development Board is Now Available for Purchase for $40

ODROID-C2 is a quad core 64-bit ARM development board based on Amlogic S905 processor with 2GB RAM that was planned to launch in early March, but maybe unsurprisingly, Hardkernel decided to launch their latest board, the very same day as Raspberry Pi 3 launch. We already knew the specifications, but it’s always useful to mind ourselves of the details: SoC – Amlogic S905 quad core cortex-A53 processor @ 2.0 GHz with 3+2 cores Mali-450 GPU System Memory – 2GB DDR3 SDRAM Storage – eMMC module socket with 8, 16, 32, or 64GB module by Toshiba or Sandisk + micro SD slot supporting UHS-1 SD cards. Video Output – HDMI 2.0 up to 4K @ 60 Hz Connectivity – Gigabit Ethernet (Realtek RTL8211F) USB – 4x USB 2.0 host ports + micro USB OTG port Expansion Header 40-pin header with GPIO, I2C, UART, and ADC ; All I/Os are 3.3V, except […]

Raspberry Pi 3 Board is Powered by Broadcom BCM2837 Cortex A53 Processor, Sells for $35

Raspberry Pi 3 board was first found on the FCC website, and thanks to various other leaks we had a pretty good idea of the board specifications including a Broadcom 64-bit ARM processor coupled with 1GB RAM, WiFi and Bluetooth, as well as basically the same features and ports as Raspberry Pi 2 Model B. But with the fourth anniversary of the Raspberry Pi Model 1 board, Raspberry Pi 3 has now officially been launched, and you can now purchase the board for $35. Raspberry Pi 3 specifications: SoC – Broadcom BCM2837 64bit ARMv8 quad core Cortex A53 processor @ 1.2GHz with dual core VideoCore IV GPU @ 400 MHz supporting OpenGL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. Capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure System Memory – 1GB LPDDR2 Storage – micro SD slot Video & Audio Output – HDMI 1.4 […]

Raspberry Pi 3 Model B Board Features a 64-Bit ARM Processor, Adds WiFi and Bluetooth Connectivity

The Raspberry Pi foundation is working on yet another model of the popular Raspberry Pi boards, as the Raspberry Pi 3 model B board has showed up on the FCC website. The new board looks very similar to Raspberry Pi 2 model B, but adds on-board WiFi 802.11 b/g/n (2.4GHz only) and Bluetooth 4.0. Let’s play “spot the difference” with Raspberry Pi 2 at the top and Raspberry Pi 3 under. The processor looks the same as the BCM2836 quad core Cortex A7 SoC found on model 2 B, but one redditer claims it could be a 64-bit processor due to some MagPi ad. [Update: that’s the MagPi ad which confirms Raspberry Pi 3 will feature a 64-bit ARM processor @ 1.2 GHz. Thanks Gabe! ] We’ll find the WiFi/BT chip antenna on the top left corner, and two through holes on the right of the 40-pin connectors, likely the […]
