ABSTRACT:
A microprocessor which is constructed to output outside a pipeline flash signal in response to a branch caused by a conditional branch instruction being to be taken, includes a decoder unit decoding and producing decoded information of each of instructions to be executed, the decoder unit further producing branch conduction information designated by the conditional branch instruction, a latch latching the decoded information in response to a write-enable signal and outputting it in response to a read-enable signal, an execution unit performing a data processing operation in response to the decoded information from the latch and including a status word register for temporarily storing an execution state thereof, and a branch detection unit for detecting whether or not a branch is to be taken in response to the branch condition information and the execution state and responding to the write-enable signal to produce a detection signal when the branch is detected to be taken, the pipeline flash signal being thereby generated in response to the detection signal.
