The company goes on to say a single Xavier-based AI car supercomputer will be able to replace today’s fully configured DRIVE PX 2 with two Parker SoCs and two Pascal GPUs. The new platform will be much smaller as illustrated below, consumes much less power at 20 Watt, or 25% of the power consumption of PX DRIVE 2, and deliver the same AI performance (20 TOPS), as well as around 33% better integer performance (160 SPECINT).

Xavier will start sampling in Q4 2017, and be available to automakers, tier 1 suppliers, startups and research institutions working on self-driving cars.

Nvidia has also uploaded a video showing the deep learning capabilities of their PX DRIVE 2 computer on a self-driving car that learned to drive in California, before driving in New Jersey.

ARM Unveils Cortex-R52 ARMv8-R CPU Core for Safety-Critical Systems

September 20th, 2016 1 comment

ARM has introduced their very first ARMv8-R real-time 32-bit CPU core with Cortex-R52 designed for safety-critical applications in the automotive, industrial and health-care markets. It has been designed to address higher workloads with increased performance (up to 35%) compared to Cortex-R5 processor.

The processor should be used in systems capable of fulfilling IEC 61508 SIL 3 and ISO 26262 ASIL D functional safety requirements. ARM explains the new processor address both random errors for example bit flipping from radiation, and systemic errors more related to software or design faults.

functional-safety-random-systematic-faults

The latter can be addresses with the right development processes, including following aforementioned functional safety standards, but random errors require some extra hardware features such as ECC memory, or dual core lock step processors, where instructions are run on two processors simultaneously and results compared.

Normally, the whole software stack must be validated and certified on safety-critical systems, even for part of the code that may not be safety-critical. This is a time-consuming and costly endeavor however, and as software becomes ever more complex becomes an issue. So Cortex R52 cores also implement a Level 2 MPU running monitor or hypervisor software, which can help separating safety code, critical safety code and non-safety code.

arm-processor-real-time-coreCortex-R52 cores would typically be used in conjunction with Cortex-A cores running non-safety code, and offering higher performance, throughput, and more peripherals. Some current processors featuring Cortex-Rxx cores include Xilinx Zynq UltraScale+ MPSoC (Cortex-R5), and Renesas R-Car H3 automotive SoC (Cortex-R7).

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

April 5th, 2016 No comments

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_PX4_PX3_PX2Rockchip 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:

  1. “Quick startup and fast revert track”
  2. Navigation system with free updates
  3. HD video recording (car DVR)
  4. Advanced ADAS algorithm to achieve the trajectory, distance between vehicles, license plate recognition, collision avoidance and other functions
  5. Dual screen support
  6. Mobile Internet control
  7. Support for 1080p H.264 decoding and voice recognition input

I could not find system or demo with dual display system with PX3 (dashboard + infotainment), but did find a video of a double DIN car stereo based on Rockchip PX3 processor and running Android 4.4.

Auto Pumpkin sells several PX3 based stereo for various car models on their website for $250 and up. Cold boot time is rather standard however (25 to 30 seconds). I found about PX3 processor via one IloveRockchip tweet boasting about a “large screen in-vehicle navigation for Dongfeng Kadjar”, but I could not find any details, as maybe the news is only reported in Chinese media.

Renesas Port board specifications:

  • SoC – Renesas R-Car M2 dual core ARM Cortex-A15 processor @ 1.5­GHz with PowerVR SGX544MP2 GPU, Renesas 2D graphics processor, and Multimedia Engine SH­4A @ 780 MHz
  • System Memory – Dual channel 2GB DDR3
  • Storage – On-board 4 MB SPI, and 64 MB SPI, 1x SATA rev 3.1 connector, 1x SD card slot, and 1x micro SD card slot
  • Video Output / Display I/F – HDMI and LVDS + touchscreen
  • Analog Video In – ADV7180 Video Decoder with RCA jack, NTSC/PAL/SECAM autodetection
  • Audio codec – AK4643EN with 3.5mm jacks for Line In and Line Out
  • Connectivity – 100 Mbps (debug) Ethernet and Ethernet AVB (Auio Video Bridge) connector
  • USB – 2x USB 2.0 ports, 1x micro USB port that supports host, device and OTG modes
  • Serial – CAN transceiver
  • Expansion
    • 1x PCI Express x1 slot
    • EXIO connector
    • IEBus (Inter Equipment Bus)
  • Debugging – 20-pin JTAG connector, micro USB port for debugging
  • Misc – Power LEDs for 12, 5 and 1.35V, power switch, 3 user buttons, reset button,
  • Power supply – 12V/9A
  • Dimensions – 170×125 mm

So the hardware is pretty interface with interfaces seldom found on hobbyist boards such as IEBus (automotive 2-wire protocol to connect multiple media devices), EXIO connector, and an Ethernet AVB bus. Video input would allow you to use some rear camera for example, LVDS and the touchscreen header a touchscreen display.

The board supports Linux built with the Yocto Project. No, I did not find at all that information on Renesas website, but instead on Porter board page on eLinux.org, which beside hardware information, including the hardware and setup guide, also provides a quick start guide to  run an “Hello, World!” application with a Yocto build supporting both X11 and Wayland.

All that would not be any fun is you could not purchase the board, but luckily R-Car M2 Porter board is sold on Digikey for $360.
