ABSTRACT:
A request scheduling method is provided in a request accessing system having a processing unit, an upstream unit coupled to the processing unit, a downstream unit coupled to the processing unit and the upstream unit, and at least one endpoint device coupled to the upstream unit and the downstream unit, wherein the endpoint device asserts at least one request to the upstream unit. The request scheduling method includes: transmitting the request to a processing unit while the request is a non-peer-to-peer request, and transmitting the request to a downstream unit while the request is a peer-to-peer request; wherein if the request is a peer-to-peer and posted request and there is a previous asserted request which is peer-to-peer and non-posted request and the previous asserted request has a latency exceeds a predetermined time, transmitting the request earlier than the previous asserted request to the downstream unit.
