Highly parallel multi-resource arbiters

Multi-resource multi-client arbiters are becoming more important in on-chip systems because of the increasing significance of dynamic, run-time, allocation of various system performance resources such as power and computation and communication facilities. Arbiters, for example, can be used to limit the amount of concurrency for regulating voltage droops, and for balancing load and traffic. This paper describes the design of multi-resource arbiters with high degrees of concurrency. By using freezing logic, this design method guarantees correct computation whilst simplifies the implementation. Quick release mechanisms and the implementation of the multi-token concept through the duplication of the client requests help improve the efficiency.
