  • System for improving two-color display operations
    Patent number: 5132670
    Abstract: A system is disclosed which reduces significantly the time for processing multi-bit two-color data for display. The system generates multi-bit two-color data by expanding single-bit monochromatic data, and provides three types of output data: a first expanded multi-bit color data, a second expanded multi-bit color data, and a third unchanged multi-bit data, the unchanged data being combinable with other data for producing data overlays.The system comprises a data expansion circuit for maintaining selected data unchanged and for expanding selected single-bit data to multi-bit two-color data, a memory for storing multi-bit data, and a data compression circuit for compressing selected multi-bit data to single-bit data.
