A 40-Mpixel/s bit block transfer graphics processor

A man-machine-interface-oriented graphics processor featuring data transfer speed of over 40 picture/s and character-front bit-mapped speed of over 15000 characters/s in a 1024*768-pixel-resolution color-CRT (cathode-ray-tube) system is discussed. The high-speed operation was attained by a memory interleaving scheme. The detailed timing for the high-speed scheme and its compactness are shown, using an actually fabricated application board. The chip layout was accomplished with a standard-cell-based approach with 1.0- mu m CMOS process.<
