Multicore processors get more and more popular, even in embedded systems. Unfortunately, these types of processors require a special kind of programming technique to offer their full performance, i.e. they require a high thread-level parallelism. In this paper, the authors evaluate the performance of different configurations of the same processor core within an SoPC: a single threaded single core, a multithreaded single core, a single threaded multicore, and a multithreaded multicore. The used core is the jamuth core, a multithreaded java processor able to execute java bytecode directly in hardware.
