PolarFire? SoC is built upon the award-winning PolarFire FPGA non-volatile FPGA platform. Featuring a five core Linux capable processor subsystem based on the RISC-V ISA, PolarFire SoC brings to market an innovative, midrange, embedded compute platform that inherits all the benefits of the PolarFire FPGA product family. The RISC-V CPU micro-architecture implementation is a simple, 5-stage single issue in order pipeline that does not 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. With Secure Boot built-in, innovative Linux and Real Time modes, a large Flexible L2 memory subsystem, and a rich set of embedded peripherals, PolarFire SoC provides designers new choices in secure, power-efficient, embedded compute platforms. This document describes the features of PolarFire SoC extended commercial (0 °C to 100 °C Tj) and industrial (–40 °C to 100 °C Tj) device offerings.
