Webeach cycle counting definition are converted into a single damage parameter (D), as used by Malholtra [2]: (1) where D is a measure of potential damage, u i is the acceleration amplitude of the i th half cycle and n is the number of cycles. Before proceeding further, it is important to note the difference between cycle counting definitions and WebLoad instructions in a program can fall into three categories: (a) constant address, (b) striding, and (c) irregular. Constant address loads are loads whose virtual address does not change over multiple dynamic instances of the load (for e.g., global variables and stack accesses). Striding loads are those with successive virtual addresses
