METHODS OF OVERRIDING A RESOURCE RETRY

In an embodiment, an apparatus includes control circuitry and a memory configured to store a plurality of access instructions. The control circuitry is configured to determine an availability of a resource associated with a given access instruction of the plurality of access instructions. The associated resource is included in a plurality of resources. The control circuitry is also configured to determine a priority level of the given access instruction in response to a determination that the associated resource is unavailable. The control circuit is further configured to add the given access instruction to a subset of the plurality of access instructions in response to a determination that the priority level is greater than a respective priority level of each access instruction in the subset. The control circuit is also configured to remove the given access instruction from the subset in response to a determination that the associated resource is available.
