May 15, 2012 -- With the advent of new highly computing-intensive mobile applications (high-throughput and software-defined radio, high-resolution video streaming, 3D image processing, augmented reality, etc.), current system-on-chips (SOCs) are quickly moving towards many-cores for increasing parallelism. As a result, the number and distance of communications between these cores are growing exponentially. This point is explaining the relative importance of communications which can account for up to 30% of overall energy consumption in the highest performing many-core architectures.
