    Abstract

    This paper examines the possibilities of providing throughput guarantees in a network-on-chip by appropriate traffic routing. A source routing function is used to find routes with specified throughput for the data streams in a streaming multiprocessor system-on-chip. The influence of the routing algorithm, network topology and communication locality on the routing performance are studied. The results show that our method for providing throughput guarantees to streaming traffic is feasible. The communication locality has the strongest influence on the routing performance while the routing algorithm has weakest influence. Therefore, the mapping algorithm is of greater importance for the system performance than the routing algorithm and it is profitable to use a more complex mapping algorithm that preserves the communication locality together with a simple routing algorithm.
