ABSTRACT:
Systems and methods for recording instruction sequences in a microprocessor having a dynamically decoupleable extended instruction pipeline. A record instruction including a record start address is sent to the extended pipeline. The extended pipeline thus begins recording the subsequent instruction sequence at the specified address until an end record instruction is encountered. The end record instruction is recorded as the last instruction in the sequence. The main pipeline may then call the instruction sequence by sending a run instruction including the start address for the desired sequence to the extended pipeline. This run instruction causes the extended pipeline to begin autonomously executing the recorded sequence until the end record instruction is encountered. This instruction causes the extended pipeline to cease autonomous execution and to return to executing instructions supplied by the main pipeline.
