Abstract

PURPOSE:To transfer picture data at a high speed under simple control with simple constitution by employing the virtual memory system for data transfer between CPU or an external equipment and a picture memory. CONSTITUTION:Read picture information is temporarily stored in picture memory 22 in the picture editing unit and the contents of memory 22 are rewritten according to various editing indications sent from the external equipment and then transferred to the plotter, so that CPU will exercise centralized control. In this case, memory 22 is fractionized into pages, memory addresses in each page are made to correspond to the memory space of CPU, and data transfer between CPU and memory 22 or that between the external equipment and memory 22 is performed by supplying the control command for page assignment from CPU to memory 22 by way of I/O port 5, and assumed to be the data transfer of the memory in the system control, thereby transferring fixed data.
