PROCESSING SYSTEM AND ARITHMETIC METHOD

摘要

PURPOSE: To provide an arithmetic processing system and method in which the processing delay of a correct instruction is less after a branch was decided to be erroneous. CONSTITUTION: A 1st instruction is processed in response to a branch instruction and a storage location is related to a 1st instruction prior to execution of a branch instruction. A 2nd instruction is processed independently of information stored before in the storage location in response to the execution of the branch instruction and the storage location is related to the 2nd instruction prior to the end of the branch instruction.
