Mi-V RISC-V Embedded Ecosystem
summary
Mi-V ecosystem packages RISC-V soft cores, an Eclipse-based SoftConsole toolchain (also supports ARM), and evaluation boards including a $99 FPGA dev board; the Hi5 expansion board pairs a PolarFire FPGA with the SiFive U540 HiFive Unleashed via an FMC/chiplink memory-mapped interface. A convolutional neural network runs as an FPGA-accelerated inference demo; a custom math block performs two multiplications and an addition in a single cycle, yielding about double performance at half the power on a TinyYOLO test. The Hi5 kit sold out on Crowd Supply.
