Abstract
A pipeline control system, in accordance with the present invention, includes a plurality of operation stages for processing instructions, the operation stages including at least one instruction issue stage wherein instructions wait to be issued. A mechanism for analyzing an issued instruction is included to determine if the issued instruction is successful without requiring stall cycles. If instructions cannot be completed successfully due to resource conflicts or exception conditions, they are aborted and reissued by the at least one instruction issue stage. A mechanism is also included for directly returning the aborted instructions to be reissued to the at least one instruction issue stage such that the instruction is reissued while the operational stages continue to process instructions. A method for pipeline control is included.
