Abstract
A method and apparatus for sequencing computer instructions in memory (24) to provide for more instruction efficient execution by a central processing unit (CPU) (22) begins by executing the computer instructions via the CPU (22) and creating a trace file (FIG. 2) in memory (24). The trace file is then scanned using a window size greater than two (i.e., more than two instructions or basic blocks/ groups of instructions are selected as each window) and correlations are determined between several pairs of instructions in each window (FIGS. 9 and 10). The correlations obtained by the window procedure are then analyzed (FIG. 11) to determine an efficient ordering of computer instructions for subsequent execution by any target CPU.
