Safety, Security and Multicore.
Paul Parkinson · SSS · 2011
Historically many safety-related and security-critical systems have been developed and qualified using single-core processors. These platforms could easily meet their increases in system performance requirements through higher processor clock speeds. However, the industry is now approaching the limit of relatively simple upgrade path, and there is an increasing trend towards the adoption of multicore processor architectures in critical systems to address higher performance demands. In this paper, we will review the challenges involved in migration to multicore processor architectures and the specific challenges related to their use in safety-critical and security-sensitive systems.
