COMMAND CONTROLLER, METHOD FOR CONTROLLING COMMAND, AND INTEGRATED CIRCUIT

摘要

A command controller for executing commands to draw images in a plurality of drawing-areas on a screen includes: a first storage storing a first command to draw an image in a first drawing-area having a first drawing-priority, among the drawing-areas; a second storage storing a second command to draw an image in a second drawing-area having a second drawing-priority lower than the first drawing-priority, among the drawing-areas; and a command execution unit executing, every predetermined period, the first command stored in the first storage to draw the image in the first drawing-area. The execution unit determines whether the first command is completely executed within a threshold-time shorter than the predetermined period from starting of the predetermined period. When the first command is determined to be completely executed within the threshold-time, the execution unit executes the second command stored in the second storage to draw the image in the second drawing-area.
