Abstract

PURPOSE:To exercise high-efficiency control without making constitution complex, by performing pushdown processing of data while forming successive areas in a buffer and a main storage by using a point which indicates their storage areas. CONSTITUTION:Through a buffer storage pointer 70, an operator 74, etc., data is written in a free block in a buffer storage 76 on a pushdown basis according to a pointer Pt1. When all free blocks in the storage 76 are used through a buffer-length register 73, the operator 74, etc., a main storage 100 is also controlled through a a control part 75, a main storage point 71, the operator 74, etc., to write data in a prescribed block in the storage 76 according to the pointer Pt1 and in a prescribed block in the storage 100 by transfer from the prescribed block, thus writing the data on the pushdown basis while block areas in the storages 100 and 76 continue. Similarly, the data are read out on a pushup basis, so the data are processed efficiently under pointer control without making the constitution complex.
