Embedded development board features Microchip PolarFire RISC-V FPGA SoC

Microchip/MicroSemi first introduced PolarFire RISC-V FPGA SoC at the end of 2018, with the chip being like the RISC-V equivalent of Xilinx Zynq Ultrascale+ Arm & FPGA MPSoC.

The following year, ARIES Embedded unveiled the ARIES M100PF system-on-module and evaluation board, before Microchip launched PolarFire SoC Icicle 64-bit RISC-V and FPGA development board, followed by the more compact PolarBerry SBC in 2020. There’s now at least a fourth platform based on PolarFire SoC with Aldec TySOM-M-MPFS250 embedded development board.

TySOM-M-MPFS250 embedded development board

The prototyping board supports Linux on the RISC-V application cores, and Aldec provides a Libero BSP (board support package) in a Github repository that contains a reference design, an MSS configuration, an HSS configuration, an Aldec meta layer for the Yocto Project, and a baremetal application

The company says the TySOM-M-MPFS250 embedded development board is best suited for the prototyping of systems for a wide range of applications such as imaging, Artificial Intelligence / Machine Learning (AI, ML), Internet of Things (IoT), industrial automation, automotive, aerospace and defense, wireless access networks and cellular infrastructure.
