<p>PURPOSE:To cope with reception of data from each terminal by means of a buffer memory of a prescribed capacity by dividing the buffer memory into plural cells and allocating dynamically these cells to each terminal device. CONSTITUTION:A control part checks how many cell parts are already used with the data related to (a terminal device of) an address A through a cell use counter part UC. A numeric character 2 is set to a counter CA and therefore data Q is stored to both cells CL1 and CL2. Then the sizes of residual parts of both cells CL1 and CL2 are checked by a writing pointer WR2 of a pointer part WA and the final address E (known already) of the cell CL2. The sizes of said residual parts are smaller than the side of received data D, a flag F3 where a numeric character ''0'' is set is retrieved within a cell control flag part MF. Then the data D is written to a cell CL3 designated by a flag F3.</p> |
