Method and apparatus for allocating computer bus device resources to a priority requester and retrying requests from non-priority requesters |
摘要 |
A target device in a computer bus system allocates resources by selecting a priority requester for allocation of scarce resources. In a non-bus arbiter configuration, the first initiator device to receive a retry response to a transaction request after the resources are exhausted is designated as a priority requester. In a bus arbiter configuration, the priority requester is chosen on a round-robin basis from initiator devices that received a retry response to the initiator's most recent transaction request. If only one resource is available when an initiator sends a transaction request, the initiator receives a retry response unless the initiator is the priority requester.
