The ET-SoC-1 chip contains more than one thousand RISC-V cores, with custom vector and tensor extensions on each core, and has recently been given a new open-source lease of life [1]. What do low-level AI software engineers do with novel hardware? Obviously the answer is to make it do matmuls.

Join me on a rapid journey from naïve matmul to optimized matmul, learning about ET-SoC-1 along the way. Some of its hardware features will help us, whereas others will be a hinderance.
