DATA PROCESSING SYSTEM WITH LATENCY TOLERANCE EXECUTION |
摘要 |
In a processor having an instruction unit, a decode/issue unit, and execution queues configured to provide instructions to correspondingly different types execution units, a method comprises maintaining a duplicate free list for the execution queues. The duplicate free list includes a plurality of duplicate dependent instruction indicators that indicate when a duplicate instruction for a dependent instruction is stored in at least one of the execution queues. One of the duplicate dependent instruction indicators is assigned to an execution queue for a dependent instruction. The dependent instruction is executed only when the one of the duplicate dependent instruction indicators is reset. |
