SiFive has introduced the SiFive Performance P870-D, a new RISC-V processor core designed for data center applications. The new P870-D not only sets the stage for RISC-V processors with up to 256 cores, but also enables building CPUs for mission-critical systems demanding the utmost reliability.
SiFive's Performance P870-D builds upon the regular P870, which is a six-wide out-of-order core with an RVA23 profile of the RISC-V instruction set architecture with vector and vector crypto processing acceleration. The P870-D adds an open AMBA CHI bridge for energy-efficient cross-cluster communications (each cluster has from one to four cores with shared L2 cache) as well as cross-cluster reliability, availability, and serviceability (RAS) features to enable building CPUs with up to 256 cores aimed at mission-critical applications.
