Abstract
Optimizing compiler performance by applying data speculation within modulo scheduled loops to achieve a higher degree of instruction-level parallelism. The compiler locates a schedule for specifying an order of execution of the instructions and allocates rotating registers for the instruction execution. Based upon the schedule and the register allocation, the compiler determines an initiation interval specifying a number of instruction issue cycles between initiation of successive iterations related to the scheduling of the instructions.
