ABSTRACT:
A system for computer pipeline operation in which a plurality of instructions are executed in parallel by commencing, before the termination of execution of the preceding instruction, the execution of the present instruction, including a conflict detection unit, a data establishment indication unit, and a source data by-pass unit. The source data by-pass unit by-passes a source data to the processing stage which requires this source data immediately after conflict is detected between the result data of the preceding instruction and the source data of the present instruction and the establishment of the source data of the present instruction is detected.
