Abstract

A direct memory access apparatus includes a CPU, and data of one byte or more to be transferred is stored in a working RAM of the CPU or an external storage unit. The external storage unit includes a memory cartridge or a CD-ROM, and stores parameter data including the number of data to be transferred, a first address and second address for direct memory access, and etc. Prior to a start of the direct memory access, the parameter data is read and, when a horizontal blanking signal is generated from a counter included in a video processor, the data is read from the working RAM or the external storage unit in accordance with the first address value and the data is transferred to an internal memory of the video processor in accordance with the second address value.
