PURPOSE:To realize a common use for multiplication of a digital circut having several degrees of multiplication, by changing the setting of the output side control circuits of the buffer memories provided in correspondence to the incoming circuits and according to the degrees of multiplication of these circuits. CONSTITUTION:The buffer memories BM1-BMn are provided at the circuit correspondence part, and the selector SEL that selects and multiplies the outputs of these buffer memories is provided. These memories and selector are controlled by a counter CTR of the like. The output information of the buffer memory BM1 is renewed based on the decoding result of the output of the counter CTR, thus carrying out a multiplication. At the same time, the division ratio can be varied by the setting for the counter CTR, and accordingly a multiplication is possible for the circuits having the same degree of multiplication only by changing the division ratio even to the input circuits having different degrees of multiplication. |
