Recently, multicore technology has been introduced to embedded systems in order to improve performance and reduce power consumption. In the present study, three SMP multicore processors for embedded systems and a multicore processor for a desktop PC are evaluated by the parallel benchmark using OpenMP. The results indicate that, even if the memory performance is low, applications that are not memory-intensive exhibit large speedups by parallelization. The results also indicate a large performance improvement due to parallelization using OpenMP, despite its low cost.
