CanMV-K230 AI development board features Kendryte K230 dual-core 64-bit RISC-V processor

CanMV-K230 development board

CanMV-K230 is a credit card-sized development board for AI and computer vision applications based on the Kendryte K230 dual-core C908 64-bit RISC-V processor with built-in KPU (Knowledge Process Unit) and various interfaces such as MIPI CSI inputs and Ethernet. The first Kendryte RISC-V AI processor was launched in 2018 with the K210 which I tested with the Grove AI HAT and Maixduino board and found fun to experiment with, but noted that performance was limited. Since then the company introduced the K510 mid-range AI processor with a more powerful 3 TOPS AI accelerator, and the K230 entry-level successor to the K210 – which was planned for 2022 in a 2021 roadmap – has now just been launched and integrated into the CanMV-K230 development board. CanMV-K230 specifications: SoC – Kendryte K230 CPU 64-bit RISC-V processor @ 1.6GHz with RISC-V Vector Extension 1.0, FPU 64-bit RISC-V processor @ 800MHz with support for […]

SiFive announces Intelligence X390 NPU, Performance P870 RISC-V core

SiFive Performance P870 RISC V Intelligence X390 NPU

SiFive has announced two new high-performance IP blocks with the Intelligence X390 NPU and the Performance P870 RISC-V core that should find their way into SoC designed for Generative AI and ML applications. We had already covered the Performance P870 and its automotive sibling – the P870-A – from information in an earlier presentation, but the SiFive Intelligence X390 NPU is new to me and appears to be aimed at generative AI in data centers, although we will very soon be seeing companies implement generative AI at the edge in pretty powerful embedded devices. SiFive Performance P870 highlights: Full support for the RVA23 RISC-V profile specification and Vector 1.0 and Vector Crypto Six-wide, out-of-order 64-bit core Up to a 32-core cluster >12 SpecINT2k6/GHz, or a 50% peak single thread performance upgrade over the previous generation SiFive Performance P670 SiFive Features 2x 128b VLEN RVV Vector crypto and hypervisor extensions IOMMU […]

OpenWrt 23.05 released with MbedTLS by default, Rust packages, over 1,790 supported devices

OpenWrt 23.05

OpenWrt 23.05 open-source Linux operating system for routers and resource-constrained headless embedded systems has just been released with over 4300 commits since the release of OpenWrt 22.03 a little over a year ago. The new release now supports over 1790 devices or about over 200 new devices compared to the OpenWrt 22.03 release with notable new targets including the ipq807x target for the Qualcomm IPQ807x WiFi 6 SoCs, the mediatek/filogic subtarget for the Mediatek Filogic 830 and 630 SoCs, and the sifiveu target for the HiFive Unleashed and Unmatched RISC-V development boards. OpenWrt 23.05 switches from wolfSSL to MbedTLS as default because the latter has a much smaller footprint and offers a more stable ABI (application binary interface) and LTS releases, but it does lack support for TLS 1.3, so users who need the latter may still switch to wolfSSL if needed. Another highlight of the new OpenWrt release is […]

Ollie v2 USB to UART/CAN/RS485/RS232 converter gets USB-C port, plastic enclosure, and more (Crowdfunding)

USB-C to UART, CAN Bus, RS485, and RS232 converter

Ollie v2 is an improved version of the Ollie USB to isolated UART, CAN Bus, RS232, and RS485 converter that gains a USB-C port, a plastic case, the ability to set the voltage from the target board, and various other minor improvements. Like the first version, the Ollie v2 is a portable tool designed for hackers and field engineers that allows them to work with a single device instead of a bunch of USB converters, each handling a single protocol, and isolation makes sure the host, such as a laptop, is protected from high voltages. Ollie V2 specifications: Serial chip – WCH CH344 quad-serial port chip (instead of XR21V1414 in the first design) Host interface – USB Type-C port Isolated interfaces (all with ESD protection) 2x UART ports up to 6 Mbps with 1.8/3.3/5 V or target voltage levels (set by slide switch) CAN 2.0A/B up to 1 Mbps bus […]
