Space system designer CAES has built the first eight core fault tolerant chip that is selectable between different architectures, including RISC-V.
The radiation hardened GR765 System-on-Chip (SoC) is the first user selectable CPU for space, allowing users to chose the legacy LEON5 SPARC V8 or the new NOEL-V RISC-V RV64 processor cores.
A test chip has been built in Europe on the 28nm FDSOI process technology from STMicroelectronics with both types of cores.
