Steady progress of De-RISC integration and validation activities

Mar 11, 2022

On the hardware side, the new pipelined high-performance Floating-Point Unit (FPU) delivered by Cobham Gaisler is working fine, with a 7x increase in floating-point performance compared to the previously integrated area-optimized NanoFPU.

The support for full-virtualization and the new H extension, adding a new privilege level to NOEL-V, is now functional in XtratuM XNG, including IRQ virtualization.

The porting of LVCUGEN to the 64-bit RISC-V architecture is ongoing, with promising results so far. The full-size configuration of the partitions in LVCUGEN, representative of state-of-the-art space applications, shows the good scalability of XNG in this regard.

A new ground station simulator has been developed to enable telemeasure and telecommand (TM/TC) communication with the Flight Software use-case application, as part of the complete platform validation.

Overall, there is a good ongoing progress in the integration and the validation of the De-RISC platform. The elements featured in the demonstrator are jointly growing in maturity.
