Abstract
A processing system includes a shared resource, an arbitration module, and a requesting device for issuing requests to the arbitration module to access the shared resource to perform transactions on the shared resource. The arbitration module grants access to the requesting device for a fixed time duration. The fixed time duration comprises one of a plurality of time durations including a first and a second time duration; the second longer than the first. The requesting device prioritizes performance of the transactions on the shared resource based upon the fixed time duration and types of transactions to be performed. Transaction type comprises one of a plurality of types including a first type that requires a time duration that can be performed within the first time duration and a second type that requires a time duration that exceeds the first time duration but can be performed within the second time duration.
