Abstract
When a branch instruction for awaiting an event is detected in an information processing apparatus which performs a pipeline process including a branch prediction, a branch prediction for the branch instruction is suppressed. As a result, a prefetch operation for an instruction subsequent to the branch instruction is promoted, and the subsequent instruction is immediately executed when the event to be awaited occurs.
