摘要
本文介绍了一种结合Round-Robin,优先级可配置的多端口仲裁器设计及实现。该设计可以实现高优先级请求优先服务,相同优先级请求之间进行轮循的调度策略,同时将原子指令仲裁保护逻辑加入到设计当中,实现了合理的时序逻辑优化,可以很好地应用于多通道访存控制器的设计当中。
In this paper, a priority configurable multi- ports arbiter design, which is based on Round- Robin arbiter technic, is introduced. The arbiter design ensures the precedence of requests with high- grades, while for requests with the same level of priorities, it adopts the polling technic, meanwhile, atom operation protecting logic is considered.Optimizations are made to the sequential logics, which ensures the designed arbiter to be applied effectively to the multi-channel memory load- store controller.
