Overview - Hardware

Platform

• 1 + 8 high-performance cores: extended RISC-V ISA
  • 1 high performance micro-controller referred to as Fabric Controller or FC (150 MHz @ 1.0V; 250MHz @ 1.2V)
  • 8 cores that execute in parallel for compute intensive tasks referred to as Cluster (87 MHz @ 1.0V; 170MHz @ 1.2V)
