Radiation-Tolerant RISC-V FPGA for Linux in space
Microchip Technology has launched a radiation tolerant version of its PolarFire FPGA with a RISC-V processor sub-system that can run the Linux operating system.
www.eenewseurope.com/, May. 01, 2024 –
The Microchip RT PolarFire system-on-chip (SoC) FPGA is the first real-time Linux capable, RISC-V-based microprocessor subsystem on a flight-proven RT PolarFire FPGA fabric.
This allows developers to start designing using the commercially available PolarFire SoC (MPFS460) device and Libero SoC development tools. Tapping into the Microchip Mi-V RISC-V ecosystem, PolarFire SoC software stacks, the PolarFire SoC Icicle Kit or the PolarFire SoC Smart Embedded Vision Kit allows the development of lower power designs for the challenging thermal environments in space.
The RT PolarFire FPGA has already received the Qualified Manufacturers List (QML) Class Q designation based on specific performance and quality requirements as governed by the Defense Logistics Agency. There is also a clear path for this device to achieve QML Class V qualification, the highest qualification standard for space microelectronics.

Safety-critical systems, control systems, space and security applications need the flexibility of the Linux Operating System (OS) and the determinism of real-time systems to control hardware. RT PolarFire SoC FPGAs feature a multi-core Linux-capable processor that is coherent with the memory subsystem. The RT PolarFire SoC enables central satellite processing capabilities similar to those in single board computers which are common in the space industry for command and data handling, in platform avionics and in payload control. The SoC allows for flexible implementation of highly integrated designs, customization and evolution of function while improving size, weight and power considerations.
