SiFive U54-MC core cluster

Realizes: low-power Linux-capable RISC-V compute

The SiFive U54-MC cluster combines four RV64IMAFD general-purpose cores with a supervisory S7 management core and coherent cache fabric, delivering low-power Linux-capable RISC-V compute used on HiFive Unmatched and Unleashed development boards.

Examples

HiFive Unmatched RISC-V developer board

HiFive Unmatched (and Unleashed) boards expose the U54-MC cluster running Debian/Yocto Linux, showcasing multi-core Linux throughput at roughly 1.5 GHz per core for 64-bit integer workloads.
