Introduction

William Armstrong is a notable inventor based in Salt Lake City, UT (US). He has made significant contributions to the field of computer graphics, particularly through his innovative patent. His work has had a lasting impact on how graphics are processed and displayed.

Latest Patents

Armstrong holds a patent for a "Computer graphics parallel system with temporal priority." This invention involves front-end processors in a graphics architecture that execute parallel scan conversion and shading. It processes individually assigned primitive objects to provide update pixels. A crossbar, along with groups of first-in-first-out registers (FIFOs), accommodates data flow to parallel pixel processors with associated memory capabilities, such as frame buffer banks. Visibility and blending operations are performed on predetermined sequences of update pixels to provide frame buffer pixels and ultimately display pixels. The pixel processors identify sequences of pixels in the display in patterns designed to equalize processor loads for pixels located along scan lines of a raster or distributed over an area. Update pixel data is tagged to identify FIFO groups, allowing for individual FIFO selection and output sequence. Temporal priority ensures that primitive data is entered in the frame buffer banks in the same order as generated at the central processor (CPU) level.
