MIPI CSI-2 v4.0 adds features for always-on, low power machine vision applications

While MIPI CSI-2 standard was first introduced in 2005 as a high-speed protocol for the transmission of still and video images from image sensors to application processors, the standard has evolved over the years, and the latest MIPI CSI-2 v4.0 introduces features to better support always-on, low power machine vision applications, high-resolution sensors, and high-dynamic-range automotive image sensors. The main changes for v4.0 include support for a two-wire interface (MIPI I3C) to lower cost and complexity, multi-pixel compression for the latest generation of advanced image sensors, and RAW28 color depth for better image quality and an improved signal-to-noise (SNR) ratio. MIPI CSI-2 v4.0 highlights: Always-On Sentinel Conduit (AOSC) – Enables always-on machine vision systems with ultra-low-power image sensors and video signal processors (VSPs) continuously monitoring their surrounding environments and having the ability to wake up their more powerful host CPUs when specific events happen. Some use cases include laptop/tablet-based face […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]

Linux 5.16 Release – Main Changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 5.16: Not a lot here since -rc8, which is not unexpected. We had that extra week due to the holidays, and it’s not like we had lots of last-minute things that needed to be sorted out. So this mainly contains some driver fixes (mainly networking and rdma), a cgroup credential use fix, a few core networking fixes, a couple of last-minute reverts, and some other random noise. The appended shortlog is so small that you might as well scroll through it. This obviously means that the merge window for 5.17 opens tomorrow, and I’m happy to say I already have several pending early pull requests. I wish I had even more, because this merge window is going to be somewhat painful due to unfortunate travel for family reasons. So I’ll be doing most of it on the road on a laptop […]

Horizon X3 AI development board is powered by Sunrise 3 AI Edge Arm processor

Horizon X3 AI development board is powered by Horizon Robotics Sunrise 3 (aka X3) quad-core Cortex-A53 processor with a 5 TOPS NPU, and multiple camera support with the chip apparently designed for the automotive industry. [Update January 25, 2022: A third-party company, Finsbury Glover Hering, claiming to represent Horizon Robotics informed CNX Software the chip is not designed for the automotive market, and that Horizon’s AIoT business is actually limited to the domestic China market and not overseas.] The devkit is comprised of a Sunrise 3 system-on-module with 1GB LPDDR4 & 16GB EMMC memory, as well as a baseboard with Gigabit Ethernet and WiFi, HDMI up to 1080p60 and MIPI DSI interface, a camera interface, and a 40-pin header for expansion. Horizon X3 AI development board specifications: SoC – Horizon Robotics Sunrise 3 quad-core Cortex-A53 processor @ 1.2 GHz, one Cortex-R5 core, a 5 TOPS NPU (2x “Bernoulli” BPU) System […]

Intel Mobileye EyeQ Ultra RISC-V processor targets Level 4 autonomous driving

Let’s carry on with Intel’s CES 2022 news, but with a twist as Mobileye EyeQ Ultra does not include any x86 cores, but instead, the automotive processor features 12 RISC-V cores, Arm GPU and DSP, and aims to bring Level 4 autonomous driving to cars thanks notably to a 176 TOPS AI accelerator. The company says EyeQ Ultra packs the performance of 10 EyeQ5s in a single package, with the single chip solution avoiding the power consumption and costs related to integrating multiple SoCs together. Intel Mobileye EyeQ Ultra specifications highlights: CPU – 12 RISC-V CPU cores (24 threads) GPU – Unnamed Arm GPU DSP – Unnamed Arm DSP SIMD cores VLIW cores Coarse grained reconfigurable array (CGRA) cores CNN accelerator clusters Two sensing subsystems One camera-only system Radar and Lidar combined system 5-nanometer process technology Mobileye provides both the chip and software with for instance high-definition map and […]
