A Bus Arbitration Scheme with an Efficient Utilization and Distribution
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2017, Vol 8, Issue 3
Abstract
Computer designers utilize the recent huge advances in Very Large Scale Integration (VLSI) to place several processors on the same chip die to get Chip Multiprocessor (CMP). The shared bus is the most common media used to connect these processors with each other and with the shared resources. Distributing the shared bus among the contention processors represents a critical issue that affects overall performance of the CMP. Optimal utilization with fair distribution of the shared bus represents another challenge. This paper introduces a bus arbitration scheme, which is an Age-Based Lottery (ABL) Arbitration that combines the lottery and age-based algorithms to overcome the shared bus challenges. The results show that the developed bus arbitration scheme maximizes the bus utilization and improves the distribution by at least 13.5% with an acceptable latency time comparing to the traditional bus arbitration schemes.
