Flow Regulation for On-Chip Communication

• We propose (sigma, rho)-based flow regulation as a design instrument for System-on-Chip (SoC) architects to control quality-of-service and achieve cost-effective communication, where sigma bounds the traffic burstiness and rho the traffic rate. This regulation changes the burstiness and timing of traffic flows, and can be used to decrease delay and reduce buffer requirements in the SoC infrastructure. In this paper, we define and analyze the regulation spectrum, which bounds the upper and lower limits of regulation. Experiments on a Network-on-Chip (NoC) with guaranteed service demonstrate the benefits of regulation We conclude that flow regulation may exert significant positive impact on communication performance and buffer requirements.
