Having reached the limits of performance gains that can be realized from miniaturization and integration, microprocessor manufacturers are more and more frequently choosing multicore processors as the best approach to increased performance in computationally intensive embedded systems.

However, realizing the potential performance gains with multicores has a cost. Software written to be single-threaded for a single core processor will realize little or no performance benefit when executed on a multicore processor. To take advantage of the cores it must be rewritten or adapted to use multithreading.
