Abstract
In one aspect, a method for managing program flow in a computer system having a processor having a prefetch mechanism and an instruction pipeline includes providing a set of program instructions having a conditional branch instruction and an system fault-causing instruction, prefetching at least one instruction into the instruction pipeline, the instruction including at least a conditional branch instruction, predicting the outcome of the conditional branch instruction; and prefetching instructions into the instruction queue based upon the result of the predicting step. The branch instruction is configured to direct program flow into or beyond the system fault instruction depending on the result of a predetermined condition.
