Abstract
Instructions to be executed by a processing system are fetched from a memory. Respective age tags are assigned to the instructions such that each of the age tags indicates an age of the corresponding instruction in the processing system. A respective physical register is allocated to each destination logical register referenced by each instruction. The respective age tags assigned to the instructions are written to respective physical registers allocated to the destination logical registers of the instructions, and to a buffer configured to maintain a program order of the instructions. The instructions are executed by the processing system. Executing the instructions includes executing at least some of the instructions in an order different from the program order of the instructions. The age tags in the buffer are used to retire executed instructions in a same order as the program order of the instructions.
