Zusammenfassung:A processor includes a time counter and a time-resource matrix and provides a method for statically dispatching instructions if the resources are available based on data stored in the time-resource matrix, and wherein execution times for the instructions use a time count from the time counter to specify when the instructions may be provided to an execution pipeline. The execution times are based on fixed latency times of instructions with exception of the load instruction which is based on the data cache hit latency time. A data cache miss causes the load instruction and subsequent dependent instructions to be statically replayed at a later time using the same time count.
