摘要：A method and system to schedule out of order operations without the
requirement to execute compare, ready and pick logic in a single cycle. A lazy out-of-order scheduler splits each scheduling loop into two consecutive cycles. The schedulingloop includes a compare stage, a ready stage and a pick stage. The compare stage andthe ready stage are executed in a first of the two consecutive cycles and the pick stage isexecuted in a second of the two consecutive cycles. By splitting each scheduling loop intotwo consecutive cycles, selecting the oldest operation by default and checking thereadiness of the oldest operation, it relieves the system of timing requirements andavoids the need for power hungry logic. Every execution of an operation does not appearas one extra cycle longer and the lazy out-of-order scheduler retains most of theperformance of a full out-of-order scheduler.
