A Comparative Analysis of Different Arbitration Protocols for Multiple-Bus Multiprocessors

Earlier performance studies of multiple-bus multiprocessor systetns assume a ran-dom selection of competing requests for bus assignment and ignore the effects of realistic bus arbitration schemes on the performance of such systetns. In this paper, we present performance analysis of the multiple-bus systems with different arbitration protocols.The priority protocols considered are random selection, fixed priority, rotating priority, roundrobin and FIFO. Analytica1 models are developed for each of these five …
