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.
