PURPOSE:To make a system compact by providing the system with a means for registering a factor for determining a programming processing condition, a table, means for branching to a processing program different at every processing condition, and a means for storing respective programs to execute the storage and processing of the programs. CONSTITUTION:A decoder 2 capable of selecting a different processing instruction in each conditions is added to the prestage or post stage of an address decoder. Since a branch instruction for selecting a condition can be indirectly executed by forming a mechanism 4 for independently executing a condition, the condition can be directly hidden from programming. Since processing means which are individually formed in an oridinary method can be used in common, the capacity of proramming can be sharply reduced.
