A low-power geometric mapping co-processor for high-speed graphics application

In this article we present a design of a low-power geometric mapping co-processor that can be used for high-performance graphics system. The processor can carry out any single or a combination of transformations belonging to affine transformation family ranging from 1D to 3D. It allows interactive operations which can be defined either by a user (allowing it to be a stand-alone geometric transformation processor) or by a host processor (allowing it to be a co-processor to accelerate certain graphics operations). It occupies a silicon area of 6 mm² and consumes 40 mW power when synthesized with 0.25mum technology
