Summary of M100PFS – POLARFIRE RISC-V SOC-FPGA MODULE
The M100PFS is a compact embedded module leveraging Microsemi's PolarFire SoC FPGA architecture. It integrates four 64-bit RISC-V cores with real-time Linux capabilities, offering high performance, low power consumption, and defense-grade security. The platform features a secure 5-stage pipeline immune to Meltdown and Spectre vulnerabilities, supporting deterministic real-time systems alongside Linux in a single cluster. It includes extensive I/O options like Gigabit Ethernet, USB, PCIe, and various serial interfaces, making it ideal for secure, high-performance embedded applications.
Parts used in the M100PFS:
- Microsemi PolarFire SoC FPGA (MPFS025T23KLE, MPFS095T, MPFS160T, or MPFS250T)
- Quad 64-bit RV64GC cores
- 64-bit RV64IMAC monitor core
- Processor I/O components (Gigabit Ethernet, USB 2.0 OTG, MMC 5.1 SD/SDIO, CAN 2.0 A/B, Quad SPI flash controller, UARTs, SPI, I2C, RTC, GPIO)
- Watchdog timers
- Processor-to-FPGA Interconnect (AXI4 and APB interfaces)
- LPDDR4 RAM (1/2/4 GByte for HMS and FPGA)
- 32 Mbit NOR Flash
- 4 – 64 GByte eMMC memory
- Clock distribution system
- Samtec QSH-090-01-F-D-A board-to-board interconnect
The M100PFS is based on the PolarFire SoC FPGA architecture by Microsemi 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.
