Abstract :
The token passing multiple access (TPMA) scheme is a common adopted scheme for wireless network-on-chip (WiNoC) in chip multi-processors (CMPs). The drawback of TPMA is the channel access delay due to TPMA passing the token in a round-robin manner no matter the node has packets to send. In this paper, we study the performance of the slotted p-persistent carrier sense multiple access (CSMA) scheme on WiNoC. A comprehensive comparison of TPMA and CSMA is given in terms of throughput and access delay in this paper. Based on the study, we show that an appropriate p for the slotted CSMA can be obtained to achieve a high performance WiNoC for CMPs.
