摘要
通过对现在存在的仲裁器类型进行研究,设计了一种基于FIFO状态的动态仲裁器,解决了传统仲裁器对带宽响应不足的问题。同时在Altera芯片构造的片上多机系统中进行了仿真测试,证明了该设计在不影响请求响应时间的基础上,能动态调整处理机的带宽比率,满足设计要求。
Various arbiters are searched and a dynamic arbiter based on FIFO status is developed to improve poor bandwidth response in this paper. The design also constructs a Multi - processor System - on - Chip used to test the arbiter. The results indicate that the arbiter can dynamically regulate bandwidth ratio without increase of response latency and satisfy design requirements.
