A decoding and regenerating device for frame coded data comprises a decoding unit (20) which decodes frame coded data which is obtained by coding time series signals of a plurality of channels by entering on a frame-by-frame basis at every channel; a regenerative data buffer memory (40) which places memory blocks to form a square matrix of rows and columns in number corresponding to the number of channels and selects alternately in every frame period a first data arrangement that regenerative data for one frame of the respective channels is stored in every row of the square matrix and a second data arrangement that regenerative data for one frame of the respective channels is stored in every column, to store the regenerative data as a stored state of the regenerative data; and a data regenerating unit (50) for reading to regenerate the regenerative data which is stored in the regenerative data buffer memory (40). <IMAGE> |
