Abstract

PURPOSE:To reduce the operating clock frequency to facilitate making the device into an LSI, by performing the operation processing of the signal of the n-th block after the PCM block signal, which is being reproduced and output, in parallel to latch it if said PCM block signal has an error. CONSTITUTION:While the sound signal of the m-th block is output from selecting circuit 18, the sound signal of the (m+2)th block and the error correcting code are read from RAM1 and are subjected to addition operation in 3 and are latched in 20 in parallel, and the sound signal of the (m+1)th block and the error correcting code are read from RAM1 and are subjected to matrix operation in 8 and are latched in 19 in parallel. Next, in respect to the (m+1)th block, contents latched in 7 are subjected to the matrix operation in 8, and the exclusive OR between these contents and contents of P register 6 is latched in 20. If an error exists in the signal of the M-th block, contents of latches 19 and 20 are selected by 18 and are output.
