一种采用双层仲裁机制的新型总线仲裁器
Novel bus arbiter with the two-level arbitration mechanism
摘要
Abstract
With the continuous increase in the complexity of the System‐on‐Chip ( SoC ) , the growing demand for bandwidth and the unpredictable wire delay have made buses the bottleneck of SoC properties;researches on efficient bus arbiters , which play a decisive role in the properties of SoC , are of great significance . In view of the decisions made by arbiters are determined by arbitration algorithms which have little reliance on hardware structures , a software simulation platform is provided in this paper to verify the properties of arbiters , on which a novel arbiter based on the structure and trans‐level judgment of the two‐level arbiter is proposed . Simulation results show that the novel arbiter would reduce the standard deviation between the actual granted ratio and the required bandwidth ratio by 54.4% and 50.8% respectively in comparison with two traditional arbiters , indicating the approximation between granted ratio and the required bandw idth ratio .关键词
