SOM BASED ON MICROCHIP’S LOW-POWER POLARFIRE RISC-V SOC FPGA

The M100PFS is based on the PolarFire SoC FPGA architecture by Microchip and combines high-performance 64-bit RISC-V cores with outstanding FPGA technology. The platform integrates a hardened real-time, Linux capable, RISC-V-based MPU subsystem on the mid-range PolarFire FPGA family, bringing low power consumption, thermal efficiency and defence grade security to embedded systems.

The RISC-V CPU micro-architecture implementation is a simple 5 stage, single issue, in-order pipeline that doesn’t suffer from the Meltdown and Spectre exploits found in common out-of-order machines. All five CPU cores are coherent with the memory subsystem allowing a versatile mix of deterministic real time systems and Linux in a single multi-core CPU cluster.
