PicoRio: An Open-Source, RISC-V Small-Board Computer To Elevate The RISC-V Software Ecosystem
summary
PicoRio builds an open-source RISC-V small-board computer and ships a working silicon plan: Pikmi SoC (TSMC 28nm, 4.3×3.4 mm, 500 MHz) with a single-channel 16-bit DDR4 controller, USB3 and a network-on-chip; the CPU fabric is four RV64 cores + RV32 always-on with a 512 KB banked cache. Software progress includes ChromiumOS imports and a V8 port that passes V8 >94% of tests, ~15k tests; full-chip power measures ~200 mW at load and targets <50 mW idle.
