Title: Richard L. Pyra and His Graphics-Processing Patents.

Introduction

Richard L. Pyra is an inventor associated with Houston, Texas, and Compaq Computer Corporation. His patent work includes innovations in video graphics controllers and line-drawing processing. The supplied information lists 5 patents in his portfolio.

Latest Patents

Two of Pyra’s latest patents concern graphics hardware and its ability to calculate and draw lines efficiently.

“Video Graphics Controller with High Speed Line Draw Processor” describes a graphics processor that receives coordinates for the two endpoints of a line. The line-drawing facility detects when the second endpoint value arrives and generates line data in response.

“Video Graphics Controller with Improved Calculation Capabilities” describes a graphics device with memories for storing line endpoints. Its state logic calculates line parameters, including a line error term, which can be stored in an error-term memory. An external source, such as a computer’s CPU, can write to that memory and modify the stored error term.
