An Adaptive Dynamic and Real-time Guaranteed Arbitration Algorithm for SoC Bus Communication ⋆

By Li Zhang, Ruizhen Wu, Yintang Yang and Fenglei Lu

Abstract

In shared System-on-chip(SoC) bus systems, arbiters are mandatory to deal with bus contentions while providing a hard real-time guarantee. In this paper, we propose a shared bus arbitration algorithm, called adaptive dynamic and real-time guaranteed arbitration algorithm. It allows high bus utilization and proper bandwidth allocation while guaranteeing hard real-time requirements. Comparisons are made between the proposed arbitration scheme and Static Priority, Round- Robin arbitration and Lottery on Virtex5 from Xilinx. Experimental results show that the proposed arbitration algorithm outperforms several commonly-used algorithms
