PURPOSE:To prevent the generation number of instruction ID from increasing so much even if the parallel degree of instructions increases and to make constitution compact by generating an instruction word based on multiplexed instruction ID. CONSTITUTION:An instruction/operand data generator 24 generates data of P-bits, which becomes the source of a parallel instruction set, at random. The multiplex ID generator 24 refers to the respective entries of an instruction generation condition reference table 22 and obtains instruction condition data 24. M-number of parallel instructions constituting one instruction word are simultaneously generated based on data of the P-bits and the instruction condition data 24. Thus, multiplex instruction ID obtained by multiplexing the instruction type code of x-bit, which identifies a source instruction word code, and identification ID of u-bit, which identifies the n-number of source instruction word codes by the number (m) of the parallel instructions is used. Then, m- number of the reference tables 22 on the formation of the instruction are simultaneously referred to and the m-number of the instructions constituting one instruction word are simultaneously generated. |
