ARM Unveils Cortex-R52 ARMv8-R CPU Core for Safety-Critical Systems

ARM has introduced their very first ARMv8-R real-time 32-bit CPU core with Cortex-R52 designed for safety-critical applications in the automotive, industrial and health-care markets. It has been designed to address higher workloads with increased performance (up to 35%) compared to Cortex-R5 processor. The processor should be used in systems capable of fulfilling IEC 61508 SIL 3 and ISO 26262 ASIL D functional safety requirements. ARM explains the new processor address both random errors for example bit flipping from radiation, and systemic errors more related to software or design faults. The latter can be addresses with the right development processes, including following aforementioned functional safety standards, but random errors require some extra hardware features such as ECC memory, or dual core lock step processors, where instructions are run on two processors simultaneously and results compared. Normally, the whole software stack must be validated and certified on safety-critical systems, even for part […]
