Delay-independent asynchronous dynamic priority arbiter for the network on chips
Yang Yintang · Journal of Xidian University · 2012
This paper proposes a delay-independent asynchronous dynamic priority arbiter to improve the quality of service in the asynchronous router of the general-purpose network on chips.In an arbitration period,by comparing the priority of the data packets with request signals,the arbiter will output the data packets in the sequence of descending priority.The packets with equal priority are outputted serially so that it resolves the problems of requests with fixed priority in conventional static arbiters,and improves the scalability of the arbiter and router.The arbiter is implemented based on 0.18 μm standard CMOS technology.Results have shown that the average response time is 0.92 ns,and that the average dynamic power consumption is 0.75 mW per request,which can be used for the asynchronous router of the general-purpose network on chips.
