Abstract
A drawing control method, a drawing control apparatus, and a drawing control system for embedded system are provided. The present invention adopts an independent drawing control apparatus to control a drawing unit to draw a frame, and move the drawn frame to an external frame buffer in advance, and therefore the number of lines that can be drawn is not restricted by the capacity of the memory of the drawing unit. Further, the present invention employs a counter to accumulate a counting number upon each time completion of drawing frame or moving frame. Whenever the counting number is accumulated, the drawing unit is controlled to perform a next stage of frame drawing or frame moving. In this concern, the present invention eliminates the time for external accessing, and thus achieving parallel processing, and instant displaying.
