Abstract
A frame buffer construction and data storage technique for computer graphics display systems are presented employing a plurality of on-chip color registers. The plurality of on-chip color registers facilitate block writing and flash writing of multiple color information into the main frame buffer video memory. Addressing of the plurality of color registers is achieved at a column address strobe (CAS) cycle page mode rate for both the loading of the registers and the block or flash writing of the contents of the registers into the main memory array.
