Abstract

PURPOSE:To elevate a multiple processing effect, and to reduce a circuit scale of a parallel-series converting and separating circuit, by combining small scale parallel-series converters in a multilevel. CONSTITUTION:An (l) bit parallel (m) multiple input is written in temporary storage devices 31-33, 3m-3m+3 and 3l/m of (m)X(m) bits having l/m pieces. Subsequently, (m) bits are read out in series by 1 bit each in an out-of-phase state from (m) number of blocks of each device 31-33, 3m-3m+3 and 3l/m, and to its output, parallel-series conversion of (m) bits is executed by parallel/series converting circuits 21-2m, and multiple (m) pieces are outputted by (m) bits each. Also, (m) pieces of separated series ouputs are outputted in an out-of-phase state by (m) number of separating circuits 11-1m. Subsequently, in the end, they are put in phase by delaying circuits 41-43 of (m-1), (m)-(m-3) (m) bits, respectively, parallel-series conversion of (l) bits is executed, (m) pieces of separated series outputs 51-5m are outputted, and a circuit scale is reduced.
