PRET-ization of uRISC Core
Original language description
Modern safety-critical embedded systems have to be time-deterministic to guarantee safety. One source of time-nondeterminism are interrupts. This paper shows how to mitigate their influence in the system on a commercially available processor IP (Codasip uRISC) can be modified to exhibit time-determinism in real-time workloads and isolate interrupts. We extend the processor with fine-grained multithreading and isolated interrupt handling to localize time-nondeterminism caused by interrupts. We show a comparison between original and extended processors on a selection of TACleBench benchmarks. For interrupt-driven workloads, ideal interrupt isolation is achieved. The proposed modification can be used on other in-order single-issue processors.
