Gaming machine

Abstract

A single processor implements both the performance control means and the image control means, providing functionality equivalent to or better than that of a configuration with multiple processors. [Solution] The sub-control board of the pachinko machine has two frame buffers that store display data for one frame, which can be used as a drawing frame buffer and a display frame buffer, and includes control means for controlling the execution of the performance, drawing means for drawing display data for displaying the performance, and display means for displaying the display data on a display device. The drawing means repeatedly executes drawing control processing and drawing execution processing in parallel on a frame-by-frame basis, and after the step of switching the drawing frame buffer and the display frame buffer is executed in the drawing control processing for each frame, the control means sets interrupt prohibition, clears the watchdog timer, and releases interrupt prohibition before the drawing control processing for the next frame starts.

Claims

[Claim 1] The system includes two frame buffers, one for storing display data for one frame, which can be used as a drawing frame buffer and a display frame buffer, and comprises control means for controlling the execution of effects, drawing means for drawing display data for displaying effects, and display means for displaying the display data on a display device, wherein the drawing means repeatedly executes drawing control processing and drawing execution processing in parallel on a frame-by-frame basis, the drawing control processing includes the steps of: commanding drawing execution based on a display list created in the previous frame, acquiring and analyzing one or more commands stored in a command buffer, creating a display list using the drawing commands acquired from the command buffer, waiting for the completion of the commanded drawing execution and then executing a vertical synchronization interrupt, and switching between the drawing frame buffer and the display frame buffer, and the drawing execution processing includes the step of drawing display data to the drawing frame buffer by executing drawing commands based on the display list created in the previous frame in response to the drawing execution command in the drawing control processing. The display means displays the display data of the display frame buffer on a display device when the drawing frame buffer is switched to the display frame buffer, and the control means sets interrupts to disable, clears the watchdog timer, and releases interrupts to disable, after the step of switching between the drawing frame buffer and the display frame buffer in the drawing control process is performed in each frame, and before the drawing control process in the next frame begins.
