PROBLEM TO BE SOLVED: To provide a game machine capable of realizing a clear image performance of high picture quality.SOLUTION: An image control unit comprises: a CPU circuit 51 for controlling an image performance centrally and generally; a CGROM 55 for storing compression data to become components of a still picture or a moving image constituting an image performance; and a VDP circuit 52 for realizing an image performance by outputting image data created from the compression data based on an instruction of the image performance CPU 51, to display devices DS1 and DS2. Data transmission/reception operations of the VDP circuit 52 and the CGROM 55 are realized by using a first differential signal line Tx for transmitting serial data in a first direction and a second differential signal line Rx for transmitting serial data in a second direction.SELECTED DRAWING: Figure 6 |
