Abstract
A method of arbitrating requests from bus masters for access to shared memory in order to reduce access latency, comprises looking ahead into currently scheduled requests to the shared memory and predicting latency of the requests based on characteristics of the currently scheduled requests, such as increasing page hit rate, or balancing read and write traffic. The requests are scheduled based at least in part on the predicted latency.
