Abstract

A data processing system includes a content addressable memory (CAM). Each entry of the CAM corresponds to a task and is configured to store a current scope of each task. A random access memory (RAM) is configured to shadow information of the CAM. Transition position storage circuitry is configured to store transition age positions for tasks. Control circuitry is configured to, in response to a command to transition a selected task to a destination scope, access the RAM to determine the current scope for the selected task, use the current scope to perform a match determination with the CAM to determine if any entries corresponding to tasks other than the selected task match the current scope; and for any matching entries, updating a transition age position in the transition position storage circuitry for the corresponding task within the current scope.
