摘要
The present invention provides an apparatus and method that increases the utilization by processors on shared resources. It provides the minimum latency in a multiprocessor system during usage right exchange between multi-processors on a shared resource. The apparatus provides a timed mailbox including a timer. The timed mailbox is at least associated with a first processor and a second processor. The second processor starts to utilize a shared resource to perform a task. According to a predetermined clock cycle number, the timed mailbox issues a signal in advance to notify the first processor of the availability of the shared resource to be utilized by the first processor.
