The GR765 is the next-generation radiation-hardened fault-tolerant octa-core system-on-chip, with the bootstrap option to select between LEON5FT SPARC V8 and NOEL-V RV64 RISC-V processor cores. It supports DDR3 SDRAM and NAND Flash memory with advanced error detection and correction capabilities. The communication interfaces include a SpaceWire router, SpaceFibre, Ethernet, MIL-STD-1553, and CAN-FD interfaces.
The GR765 is targeted at high-performance general-purpose processing with support for mixed-criticality applications. The architecture is suitable for both symmetric and asymmetric multiprocessing and contains design extensions to provide hardware support for isolation between mixed-criticality applications.
The GR765 is immediately supported by development tools such as the GRMON software debugger and various compilers and operating systems and a flight-quality boot loader for flight.
We can provide FPGA prototypes of the GR765 design for various FPGA platforms.
The full GR765 development from concept to flight model availability has the following engineering activities:
