Method of arbitration which allows requestors from multiple frequency domains |
摘要 |
The present invention provides a method of arbitration for resources which allows requestors from multiple frequency domains. Most requestors generate requests at full speed. A small number of low-speed requesters generate requests every two full-speed cycles, and hold their requests for two full-speed cycles. The arbitration method gives priority to the requests from the low-priority requesters and guarantees that two requests made by the half-speed requestors at the beginning of a low-speed cycle will be granted over the course of the low-speed cycle. The requests generated by the low-speed requestors are issued in phases. Issuance of later phases of a request is blocked when the request has been granted in an earlier phase.
