Abstract

To be able to accurately draw display data for a performance image while suppressing delay.SOLUTION: In a Pachinko machine 1000, drawing means (drawing circuit 1253) repeatedly executes drawing control processing and drawing execution processing in parallel on a frame-by-frame basis. The drawing control processing instructs drawing execution based on a display list (DL) created in the previous frame, acquires and analyzes commands from a command buffer, creates a DL by the acquired drawing commands, executes a vertical synchronization interrupt after the end of the drawing execution, and switches between a drawing frame buffer and a display frame buffer. In the drawing execution processing, display data is drawn in the drawing frame buffer by executing a drawing command on the basis of the DL created in the previous frame, in response to the instruction of the drawing execution. Display means (display circuit 1257) displays the display data in the display frame buffer on a display device, when the frame buffer is switched.SELECTED DRAWING: Figure 66

Claims

【Claim 1】 Two frame buffers for storing display data for one frame can be used as a drawing frame buffer and a display frame buffer, drawing means for drawing display data for effect display, display means for displaying the display data on a display device, comprising: the drawing means repeatedly executes in frame units in parallel with a drawing control process and a drawing execution process, the drawing control process includes: a step of instructing drawing execution based on a display list created in the previous frame, a step of obtaining and analyzing one or more commands stored in a command buffer, a step of creating a display list based on a drawing command obtained from the command buffer, a step of executing a vertical synchronization interrupt after waiting for the end of the instructed drawing execution, a step of switching between the drawing frame buffer and the display frame buffer, and the drawing execution process includes: a step of executing drawing of display data in the drawing frame buffer by executing a drawing command based on a display list created in the previous frame in response to an instruction for drawing execution in the drawing control process, the display means displays the display data of the display frame buffer on the display device when the drawing frame buffer is switched to the display frame buffer, A gaming machine characterized by the above.
