ABSTRACT:
In the image processor system of the invention, an image processor and a plurality of image memories are connected through a plurality of image buses. The image processor and image memories are also connected through a control bus, as is a CPU. The image processor has a start signal output gate circuit. When the gate circuit is initiated by the CPU, it simultaneously outputs start signals designating image data output to the image buses designated by the CPU. Each image memory has a start signal input gate circuit and an output gate circuit. The start input gate circuit receives the start signal from the image bus designated by the CPU through the control bus. The output gate circuit starts image data output to the designated image bus in response to the start signal received at the start signal input gate circuit and in synchronism with the bus cycle of the image bus.
