SPARCs in Space: The Cobham UT700 Leon3FT Processor

• nullc 3y ago
  I wonder if there are commercially available fault tolerant RISC-V chips yet?
  • kramerger 3y ago
    The CPUs are designed by Graisler Research in Sweden, who have decades of experience in space electronics and probably have thousands of CPUs currently orbiting the earth. And yes, they have RISC-V versions but I don't think they have been battle proven as much: https://www.gaisler.com/index.php/products/processors/noel-v https://www.gaisler.com/index.php/products/processors/noel-v

      That appears to be a soft CPU...VHDL for an FPGA, rather than an actual CPU.

        They are defently targeting chips.
      • kramerger 3y ago
        It targets both ASIC and FPGA.

    I do not know about commercially available, but the ESA has long selected the RISC-V NOEL-V[0] to succeed LEON in their space endeavors. 0. http://microelectronics.esa.int/riscv/rvws2022/index.php http://microelectronics.esa.int/riscv/rvws2022/index.php
