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, the authors 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 Virtex-5 from Xilinx. Experimental results show that the proposed arbitration algorithm outperforms several commonly-used algorithms.
