Abstract:
Safety critical embedded systems in the automotive domain will increasingly depend on parallel processing architectures. Since concurrency has largely been exploited on task level, future applications will feature growing proportions of parallel implementations on data level such as loop parallelism. Efficient memory utilization becomes inevitable to overcome future challenges facing the memory wall in modern computing. This work suggests an approach for data locality conscious memory accessing and data distribution implementations in embedded multi-core systems. The results have been validated by a case study on a modern Engine Control Unit focusing on the parallelization of widely spread array intensive loops.
