ABSTRACT:
A system and method of merging and manipulating pixel information for display on a raster scan monitor is disclosed. The invention operates at speeds imperceptible to the viewer by collecting, in each memory access cycle, the data representing multiple pixels and by performing merge and manipulation functions on pixel groups at video rate under control of control data from a state machine. The state machine allows for unique processing decisions to be made for every pixel group displayed on the monitor.
