Abstract
A method and mechanism for shortening the execution time of certain macro-instructions by looking at both a present macro-instruction and a next macro-instruction. The invention includes two, interrelated aspects for accomplishing this. First, a first operation of a next macro-instruction is performed concurrently with a last operation of a current macro-instruction. Second, the next macro-instruction is decoded to determine the minimum number of clock cycles it requires. If this minimum number is below a specified number, the micro operations of the present instruction are modified to perform appropriate set-up operations for the next macro-instruction to enable it to be completed in the computed minimum number of clock cycles.
