Title: The Innovations of John Anthony Metcalfe

Introduction

John Anthony Metcalfe is a notable inventor based in Dunstable, GB. He has made significant contributions to the field of technology, particularly in the area of rendering systems. With a total of four patents to his name, Metcalfe's work has had a considerable impact on how graphical data is processed and displayed.

Latest Patents

One of Metcalfe's latest patents is focused on systems and methods of partial frame buffer updating. This innovation includes a pixel source that produces data for a rendered surface divided into regions. A mapping identifies memory segments that store pixel data for each region of the surface. The mapping can also identify memory segments that store pixel data from a prior rendered surface for regions that remained unchanged during rendering. The changed or unchanged status is tracked on a region-by-region basis. Additionally, a counter can be maintained for each memory segment to track how many surfaces utilize the pixel data stored therein. A pool of free memory segments can also be maintained. Reading a surface, such as for display by a display controller, involves identifying and reading the mapping to locate each memory segment storing pixel data for the regions of the surface, reading such data, and updating the counters for the memory segments that were read.
