Sipeed M1 RISC-V Computer Vision Module Features Kendryte K210 Processor

Just a few days ago, I wrote about Kendryte KD233 board featuring Kendryte K210 dual core RISC-V processor, with some fairly detailed documentation, public links to toolchains and other tools. and going for $50. But the team behind LicheePi boards informed me that they also made their own K210 module called Sipeed M1 and selling on Taobao for the Chinese market, as well as on Yoycart for $10.89 plus shipping for the oversea market, and you’ll find a devkit with a dock board for about $24 and up depending on options. Sipeed M1 module specifications: SoC – Kendryte K210 dual core 64-bit RISC-V processor @ 400 MHz with KPU CNN hardware accelerator, APU audio hardware accelerator, 6 MB general purpose SRAM, 2MB AI SRAM memory, and AXI ROM to load user program from SPI flash Package – 72-pin (25.4 x 25.4mm) But you’ll probably want to get start with M1 […]

$50 Kendryte KD233 Board Features K210 Dual Core RISC-V SoC

RISC-V is talked about a lot, and we’re started to see a few development boards coming to market, or at least being announced with some based on SiFive processors such as HiFive Unleashed or Arduino Cinque, as well as other like GAPUINO GAP8 for low power A.I. applications. The Arduino board is not for sale yet, and HiFive Unleashed and GAPUINO GAP8 are fairly expensive at $999 and $229. Kendryte KD233 board is another RISC-V development board, based on Kendryte K210 dual core 64-bit RISC-V processor designed for machine vision and “machine hearing”. The board goes for $49.99 on AnalogLamb. Kendryte KD233 board specifications: SoC – Kendryte K210 dual core 64-bit RISC-V processor, KPU Convolutional Neural Network (CNN) hardware accelerator, APU audio hardware accelerator, 6MiB of on-chip general-purpose SRAM memory and 2MiB of on-chip AI SRAM memory, AXI ROM to load user program from SPI flash Storage – 128 Mbit […]

LicheeTang Anlogic EG4S20 FPGA Board Targets RISC-V Development

LicheePi has already made some interested little development board in the past with products such as LicheePi Zero, and the recently-announced SD card sized LicheePi Nano board, but their latest development board may ever be more intriguing. LicheeTang features Anlogic EG4S20 FPGA – unrelated to Amlogic – which run a RISC-V softcore, and all is packaged in a small small form factor as we’ve come to expect with LicheePi boards. LicheeTang specifications: FPGA – Anlogic EG4S20BG256 with 20K logic unit (LUT4/LUT5 hybrid architecture), about 130KB SRAM, 64MBit SDRAM Storage – 8Mbit flash, micro SD card slot, optional SPI NOR flash Expansion Connectors FPC40P socket for RGB LCD, VGA adapter board, or high speed (12-bit 1MSPS) DAC module FPC24P socket for DVP camera, or high speed ADC module Through holes and castellated holes exposing over 130 I/Os Debugging – FPGA JTAG chip connected over micro USB port Misc – RGB LED […]

GAPUINO GAP8 is a $229 RISC-V MCU Developer Kit for A.I. Applications

GreenWaves GAP8 is a low power RISC-V “MCU class” processor with eight compute cores optimized for artificial intelligence applications, and its main selling point is the ability to do tasks like computer vision or audio processing at very low power, even good enough to run on batteries. When we first covered GAP8 RISC-V processor at the beginning of the year, the company also mentioned a development kit comprised of GAPDUINO Arduino compatible board, a sensor board, and a QVGA camera module to experiment with the solution. The board and development kit are now easier to purchase as the devkit is sold on SeeedStudio for $229. GAPuino board specifications: SoC – GAP8 IoT Application Processor with 8x RISC-V compute cores, 1x RISC-V fabric controller core delivering up to 200 MOPS at 1mW and >8 GOPS at a few tens of mW Memory / Storage – HyperBus combo DRAM/Flash with 512 Mbit […]

Arm Compares Arm & RISC-V Benefits in RISCV Basics Website

Arm is a dominant force in mobile and embedded processors, but recently we’ve heard more and more about RISC-V open source and royalty-free alternatives, and for example SiFive has launched both application processors / IP with solutions like Linux capable Freedom U540 SoC found in HiFive Unleashed board, as well as RISC-V MCU Cores competing with Arm Cortex-M4 and Cortex-M0+ cores. There’s certainly a lot of activity around RISC-V, but I have not seen many commercial solutions yet, and the platform needs to mature. However, Arm apparently takes the competition seriously with the company setting up a website – riscv-basics.com – comparing Arm and RISC-V, notably through the infographics below. Arm recognizes RISC-V has no recurring license fees, but claims those fees are only a small fraction of the total investment required for a commercial processor. The company also questions RISC-V maturity, and at this stage is may be true, […]
