M1108 AI accelerator chip delivers up to 35 TOPS for high-end edge AI applications

Last week, Mythic announced a breakthrough with compute-in-memory technology based on a 40 nm process with what the company claims to be the industry’s first Analog Matrix Processor. The M1108 AMP AI accelerator chip targets high-end edge AI applications including smart home, AR/VR, drones, and is said to set a benchmark in the industry for high performance and low power in a single cost-effective device, also available in M.2 and PCIe form factors. The M1108 comes with an array of flash cells, ADCs, a 32-bit RISC-V nano-processor, a SIMD vector engine, SRAM, and a high-throughput Network-on-Chip (NOC) router. With 108 AMP tiles, the M1108 provides up to 35 Trillion-Operations-per-Second (TOPS) enabling ResNet-50 at up to 870 fps. This enables a power-efficient execution of complex AI models such as ResNet-50, YOLOv3, and OpenPose Body25. The industry leader NVIDIA also has a similar AI accelerator chip NVIDIA Xavier AGX which delivers up […]

BBC Doctor Who “HiFive Inventor” Coding Kit aims to teach IoT to kids

In what should be one of the first RISC-V education platforms, the BBC, Tynker, and SiFive have just announced the BBC Doctor Who “HiFive Inventor” Coding Kit that comes with an MCU board with WiFi & Bluetooth and guided lessons for kids that teach them to code for the IoT. The HiFive Inventor board is based on a SiFive FE310 RISC-V microcontroller ( the same chip as found in the HiFive1 board) and an ESP32 Solo module for WiFi 4 and Bluetooth 4.x/5.x connectivity. Just like the BBC Micro:bit, HiFive Inventor provides a kids-friendly edge connector with I/O, an LED matrix, sensors, and more. The kit includes the HiFive Inventor hardware platform, a battery holder for three AA batteries (not included), the HiFive Speakers, an illuminated USB cable for power and programming, and alligator clips to connect the speaker or other add-ons to the HiFive Inventor board. HiFive Inventor board […]

XuanTie C906 based Allwinner RISC-V processor to power $12+ Linux SBC’s

Alibaba unveiled Xuantie-910 RISC-V core (aka XT910) in 2019 for powerful SoC with up to 16 cores, but an update in 2020 revealed the company planned to have a complete RISC-V core family for a wide range of application from low-power microcontrollers to server SoCs. At the time, I just assumed the company planned to keep their cores to themselves, but time proved me wrong as T-Head, the Alibaba subsidiary in charge of developing RISC-V cores, started to cooperate with Allwinner to develop open-source processors, which should lead to low-cost Linux capable RISC-V SBC very soon according to a tweet from Sipeed. Good News: We get first chip which based on XuanTie C906 (RV64GCV), it have abundant interface (HDMI/RGB/DVP/MIPI/GMAC/…), and will be able to run Debian system.Last and most important, the basic dev board price is start at 12.5$ (1% of HiFive Unleashed)。 pic.twitter.com/EJbXTJ5eMb — Sipeed (@SipeedIO) November 6, 2020 […]

Telink TLSR9 Wireless Audio & IoT RISC-V SoC integrates RISC-V DSP/SIMD P-extension

At the end of last month, there was a lot of buzz about Bouffalo BL602, one of the first RISC-V SoC with built-in wireless connectivity, namely WiFi 4 and Bluetooth 5.0 LE. We should expect more and more of those types of solutions, and Telink & Andes jointly introduced TLSR9-series of wireless audio chips for hearables, wearables, and other high-performance IoT applications. The chips are powered by an Andes D25F RISC-V 5-stage core that happens to be the first core to integrate RISC-V DSP/SIMD P-extension and offer Bluetooth 5.2, Zigbee 3.0, HomeKit, 6LoWPAN, Thread, and/or 2.4 GHz proprietary protocol. The press release focuses on the Andes core, but an article in Chinese allows use to find more about Telink TLSR9 family’s key features: CPU – Andes D25F 32-bit RISC-V 5-stage core @ up to 96 MHz (2.59 DMIPS/MHz and 3.54 CoreMark/MHz) with RISC-V DSP/SIMD P-extension Optional NNU – AI engine […]
