It finally happened! A raspberry pi like device, with a RISC-V CPU supporting the v extension. Aka RVV. Aka vector instructions. I bought one, and explored it a bit. SIMD background First some background on SIMD. SIMD is a set of instructions allowing you to do the same operation to multiple independent pieces of data. As an example, say you had four 8 bit integers, and you wanted to multiply them all by 2, then add 1. You could do this with a single operation without any special instructions...
