This thesis first looks at the implementation of three primitive operations useful when manipulating images - Mirror, Rotate and Translate (BitBit). When implemented on conventional bitmap systems these fundamental operations require extensive memory and processor activity. Alternative architectures for bitmap graphic systems are explored. Two new architectural elements that significantly improve system performance are defined. The first, a RasterOp unit, combines four bitmap images under arbitrary merging operations at video data rates. The second element, called an Image Prism, generates orthogonal image transformations on bitmap images without requiring processor interaction. As a result, these fundamental operations can be performed several hundred times faster than before. VLSI implementations of each are described and their performance is reviewed. The second thrust of this research focuses on the design and development of a research display device. Three major architectural components of traditional CRT-based bitmap display system - frame buffer, display controller and display device - are integrated into a single, exceptionally thin, flat display device of which several working prototypes have been built. The entire display device is constructed using conventional microelectronic IC fabrication processing technology.
