ABSTRACT:
A method and apparatus for improving bandwidth of sequential access to a display data memory. Display data and tag information related to consecutive data repetitions are stored. No display memory access is needed to output data to the CRT during the time periods when data is being repeated, thus increasing display memory bandwidth. Display data from a location in display memory is stored in a latch, and is output from the latch until the tag information indicates no more data repetitions occur.
