It was while watching Bryan Cantrill’s presentation “The Soul of a New Machine”1 that my interest for RISC-V was piqued. I vaguely remember looking at RISC-V a while ago but at the time hardware wasn’t readily available unless you had an FPGA to run it on. Nowadays there’s ample choice of both 32-bit and 64-bit hardware to buy. No RISC, no fun First off, a very brief introduction to RISC-V and the different extensions which are available.
