PURPOSE:To improve the use efficiency of a memory by divisionally using one memory by plural sort cells. CONSTITUTION:Memory addresses from plural sort control parts 22-1 to 22-n are converted by an address conversion part 23, and address spaces whose storage capacities correspond to the numbers of stages of sort control parts 22-1 to 22-n are allocated on an external memory 24. Therefore, it is unnecessary to prepare a buffer memory for each sort cell, and the use efficiency of the memory is sufficiently improved. |
