Abstract

PURPOSE:To save the reduction in the scale of a circuit with the effect of multiplex processing, by the combination of a small scale serial parallel conversion at multiplex level. CONSTITUTION:m Sets of serial inputs 1-m are shifted for the phase by m- bit with delay circuits 32-3m and become m sets with multiplex by each m- bit with m sets of multiplex circuits 41-4m. The m-bit multiplexed with m sets of m-bit serial parallel conversion circuits 5a-5m is expanded in parallel and written in temporary storage devices 61-6m, 6(m+1)-6(l/m)inl/m sets of (mXm)-bit. Further, when the parallel expansion data in l-bit is stored in a temporary storage device, the data is sequentially read out and the multiplexed l-bit parallel expanded output is obtained. But this is effective only when l is a multiple of m<2>, where m is an arbitrary positive integer.
