Overview

The highest performance P870-D is targeted for datacenter applications which benefit from parallelism, including storage, web servers and video streaming. The P870-D can be used standalone or in conjunction with a member of the SiFive Intelligence Processor Family.

P870-D is fully compliant with the RVA23 RISC-V Instruction Profile. It incorporates a shared cluster cache enabling up to -32 cores to be connected coherently. Use of a CHI bridge expands this to 256 CPU coherent cores, connected either in an SoC or as a set of discrete chiplets.

  • RAS architecture to configure and reports errors in a manner compatible with RISC-V defined standard.
  • Power management with cluster-level DVFS and idle power modes
  • Supporting System IP, IOMMU, WorldGuard, Virtualization, Trace and Debug

Key features

  • Highest performance
  • 64-bit, Six-wide, out-of-order core
  • >2 SpecINT2k7 / GHz *
  • Up to 64 clusters, max 256-cores, either on-chip or via chiplet connectivity
