CRT control apparatus for use in high-resolution graphic display equipment of the type including a graphics processor (20) and a frame buffer (24) having storage banks (A, B, C, D) for storing digital signals representing the color intensities of red, green and blue colors of pixels to be presented on the CRT screen. The apparatus includes an MOS integrated-circuit (IC) chip (50) which serves as the master timing control for the entire CRT sub-system, including timing of the read-out of pixel signal from the frame buffer (24), loading of the pixel signals into latches (42) on the MOS chip (50), and multi-plexing of the signals stored in the latches (42). Digital signals representing the color intensities are directed to corresponding DACs (80, 82, 84) which generates the analog intensity color signals for the electron guns of the CRT. |
