An Irreversible Transition towards Multicore Platform in Safety-critical Domain for the Aviation Industries

Authors(2) :-Nagalakshmi K, Gomathi N

In modern safety-related application domains, the shift from unicore to multicore processors is becoming inevitable to keep pace with the growing importance of computational capacity and to satisfy the functional consolidation trend while decreasing energy consumption and thermal hotspots. Nevertheless, typical multicore processors are mostly intended to enhance the system performance, whereas safety-critical systems (SCS) have very different demands in terms of safety, reliability, quality of service, predictability and timing correctness. Hence, the move towards multicore processors imposes many significant challenges the computing industry has to tackle. These challenges are involved in designing of certifiable multicore architectures, the organization of common resources and assimilation of concurrent software. Hence, these are encountered at all phases of the specification, design, development, testing, and certification processes. Hence, both multicore industrialists and the real-time community have to fill the gap to meet the requirements enforced by SCS. The objective of this paper is to initiate such a discussion as an effort to fill the gap between the two domains and to substantially increase the cognizance of the obstacles and issues that need to be handled in the safety-critical domain.
