Abstract

PURPOSE:To increase the diversity of processing and to perform complicated processing without decreasing a processing speed, by decoding the output of a register as one instruction and by achieving instruction execution corresponding to the decoding result. CONSTITUTION:Instruction codes, when inputted from a terminal 2 in parallel, are stored first in a register 5 through an input and output register 3 and an internal bus 4. At the following timing, different instruction codes, when inputted from the terminal in parallel, are also stored in a register 6 through the input and output register 3 and the internal bus 4. Thus, as the instruction codes are stored, differing in timing, in the registers 5 and 6, they are led as one instruction code, to an instruction decoder 7, whose decoding result is supplied as a control signal to an instruction execution part CPU.
