Abstract
PURPOSE: To simplify a return process by providing a buffer block control table which provides the linear control of empty buffer blocks and full buffer blocks.
CONSTITUTION: To address part 7 in empty block control region 6-0 of buffer block control table 5, next address information of external memory unit 2 is set and to address part 8, address information of a terminal buffer block is set while the number of empty blocks is set to number part 9. Then, next address information is set to empty address parts 10-3, 10-6 and 10-1 of corresponding regions 6-3, 6-6 and 6-1 of empty buffer blocks 3-3, 3-6 and 3-1. On the other hand, next address information is set to next address parts 10-2, 10-4 and 10-5 of corresponding blocks 6-2, 6-4 and 6-5 of full buffer blocks 3-2, 3-4 and 3-5. To return blocks 3-2, 3-4 and 3-5, contents of address part 8 and number part 9 are rewritten and address information of initial full block 3-2 is set to the next address part of corresponding area 6-1 of a terminal empty block.
