Abstract

A cascaded device for graphic processor, which is used for cascading one primary graphic processor and at least one secondary graphic processor, includes: 1. one timing generator used for generating the control timing and synchronous signal needed for each graphic processing, and being able to generate or receive one pixel sync. signal and one field sync. signal to make the scanning timing synchronous with every graphic processor; 2. one pixel sync. device used for making the color code and level code of every graphic processor synchronous with the pixel sync. signal of main graphic processor; 3. one level comparator used for comparing the level code of one graphic processor output from the pixel sync. device with the level output from the one-stage lower graphic processor, and transmitting the higher level code resulting from the comparison to the former graphic processor; 4. one cascade control device used for receiving the level codes output from the level comparator and from the pixel sync. device and based on it to control the color code output; 5. one color code output device used for receiving the color code from the pixel sync. device and under the control of control signal from the cascade control unit to decide if the color code is output.
