De-RISC – Dependable Real-Time Infrastructure for Safety-Critical Computer Systems

Abstract

The space domain demands increased performance, reliable and easy to verify and validate platforms tomatch the requirements of highly autonomous missions and systems that need to undergo qualification and certification against safety guidelines, and be commercialized worldwide minimizing export restrictions. Unfortunately, commercial platforms either fail to match domainspecific requirements for space (e.g. safety requirements), are limited by US export regulations, or simply fail both sets of requirements. This paper introduces De-RISC, a novel HW/SW platform meeting space requirements for safety- and mission-critical applications by construction, with explicit support to ease performance validation and diagnosis, and based on the RISC-V instruction set architecture. The De-RISC platform, which builds upon fentISS’ XtratuM hypervisor and a Cobham Gaisler (CG) NOEL-V based MPSoC, will reach commercial maturity in 2022, and will be assessed against a space use case.
