PROBLEM TO BE SOLVED: To facilitate the development of microprograms and to enable easy reading by successively executing plural microporgrams according to the speed of an arithmetic section. SOLUTION: The selected terminals of selectors 110 to 112 are alternately switched to the terminal A and the terminal B according to clocks ϕ1 and ϕ1-. Arithmetic section input and arithmetic section output alternately execute computation by the microinstructions of the microprograms P1 and P2 according to the clocks ϕ1 and ϕ1-. For example, the outputting of the result of the computation with respect to the data inputted to the arithmetic section in a section 501 by the microinstruction of the microprogram P1 is the section 502 next to the next. The computation is execute by the microinstruction of the microprograms P2 in the section 503. Namely, even if such a microprogram which command the computation in a certain step and uses the result of the computation in the next step thereof are written, the next step is eventually executed in the next section apart one section after the section where the certain step is executed. |
