Abstract
A branch instruction executing device, for sequentially executing instructions in a pipeline process, a) decodes a conditional branch instruction, b) provides a debug exceptional producing flag for indicating the existence of the execution of the debug routine by assuming the success of the condition without waiting for the result of the determination of the condition and c) corrects a content of the debug exception producing flag when the result of the actual determination is later obtained. The execution of the debug routine is canceled when the branch condition is later found not to be successful.
