Hackaday Article: New Part Day: The RISC-V Chip With Built-In Neural Networks

By October 9, 2018May 12th, 2021No Comments

After exploring a few random online shops one day, [David] (thanks for sending this in, by the way) ran across a very interesting chip. It’s a dual-core, RISC-V chip running at 400MHz. There’s 6 MB of SRAM on the CPU, and there’s 2MB for convolutional neural network acceleration. There is, apparently, WiFi on some versions. There are already SDKs available on GitHub, and a bare chip costs a dollar or two. Interested? Log in to Taobao, realize Taobao does pre-orders, and all this can be yours.
A bit of googling tells us this chip comes from a company named Kendryte, and here the specs are repeated: this is a dual-core RISC-V with an FPU, a bunch of RAM, and can run TensorFlow. Documentation is available, although the datasheet will need to be translated, and as of this writing there’s a GitHub filled with SDKs and examples, with some of the repos updated in the last hour.
Over the years we’ve seen a few RISC-V chips given development boards, and you can buy them right now. The HiFive 1 is an exceptionally powerful microcontroller with processing power that puts it right up against the Teensy (which is built around a Freescale chip), but it’s also fairly expensive. We’re not sure the Arduino Cinque (also RISC-V) ever made it to production, but again, expensive. The idea that a RISC-V microcontroller could be available for just a few dollars is very interesting, it even comes with SDKs and utilities to make the chip useful.
