Abstract
A frame buffer memory controller allows rapid image updating while maintaining screen refresh data flow rate. One frame buffer memory controller controls one or more pixel depth columns comprising one or more frame buffer memory chips per pixel. Each frame buffer memory controller listens on a display processor bus for read, write or read-modify-write commands addressed to a pixel, or memory chip, under its control. Such commands, along with the associated addresses and data, are stored in a first-in, first-out (FIFO) buffer for execution during the first free memory cycle.
