  • Hidden job start preparation in an instruction-parallel processor system
    Patent number: 7565658
    Abstract: The read latency caused by job start preparation of a future job is at least partly hidden within the current job by reading information for job start preparation of the future job integrated with the execution of the current job. Instructions for job start preparation are preferably instrumented (701) into the current job and executed (702), whenever possible, in parallel with the instructions of the current job. The integrated job start preparation may include table look-ups, register file updating, instruction fetching and preparation. If the scheduled job order is allowed to change during execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution of the next job and take appropriate actions (704; 705, 706) depending on the outcome of the test.
