Abstract
Providing references to previously decoded instructions of recently-provided instructions to be executed by a processor is disclosed herein. In one aspect, a low resource micro-operation controller is provided. Responsive to an instruction pipeline receiving an instruction address, the low resource micro-operation controller is configured to determine if the received instruction address corresponds to an instruction address in short history table. Short history table includes instruction addresses of recently-provided instructions having micro-ops in a post-decode queue. If the received instruction address corresponds to an instruction address in short history table, the low resource micro-operation controller is configured to provide reference (e.g., pointer) to the fetch stage that corresponds to an entry in the post-decode queue in which the micro-ops corresponding to the instruction address are stored. Responsive to the decode stage receiving the reference, the low resource micro-operation controller is configured to provide the micro-ops from the post-decode queue for execution.
