Abstract:
A load store pipeline 18 includes an issue queue 20 and load store circuitry 24. The load store circuitry 24 includes the plurality of access slot circuits 26 to 40. Dependency tracking circuitry 42, 44, 46, 48 serves to track a freeable number of access slot circuits 26 to 42 corresponding to the sum of access slot circuits that are empty and those processing data access instructions which have not bypassed any preceding data access instructions within the program execution order.
