ABSTRACT:
A data processor being provided with a microdecoder which decodes instruction codes comprising two operation code parts, a source operand specifying part and a destination operand specifying part, wherein an optional bit area of source data (a register of a general register file or a memory) is inserted in an optional bit area (determined by the value of the first operation code part) of a destination register according to the decoding result, and an optional bit area (determined by the value of the second operation code part) of a source register is extracted and stored in an optional bit area of destination (a register of the general register file or the memory), thereby making it possible to "process the insertion and extraction operations to and from optional byte positions of registers" at a high speed with short instruction code size.
