Abstract
PURPOSE: To reduce a buffer memory per circuit while increasing circuits per channel in number, by providing a common stand-by buffer memory between a redundancy suppression code circuit and file memory.
CONSTITUTION: Between redundancy suppression code circuit 1 and file memory 7, (l)-sheet common stand-by memory 8 corresponding to no circuit is provided which is connected to buffer memories 21W2n of (n)-circuit-multiple common memory constitution with the (m)-number sheets of memory for each circuit. As a result, if the (m)-number sheets of memory of a certain circuit are full of signals, buffer memory control circuit 3 switches stand-by memory change-over switch 10 to store signals in memory 8. On detecting memory 8 being full of signals, common stand-by memory control circuit 9 sends an output request to common control circuit 4. Circuit 4 exercises a supervision over what circuit is using memory circuit 8 and releases change-over switch 10n of a full in-use circuit. Therefore, even if a circuit low redundancy exists, this circuit can be prevented from overflowing to a certain degree.
