ABSTRACT:
A visual display system that provides a high speed method for reading data from a pixel memory, modifying it if desired, and then writing data into the memory. This READ/MODIFY/WRITE is accomplished by providing a RAM look-up table having a number of addressable locations. The output from one addressable location is data representative of the color/intensity of the vector being drawn, the output from other addressable locations is data representative of a desired highlight color/intensity, and the addresses of the table correspond to the data representative of the different colors/intensities. The portion of the pixel memory corresponding to the pixel to be drawn is read to an address to the RAM, and the resulting data output from the RAM is written into the pixel memory register.
