Abstract
This invention relates generally to hardware for scaling and filtering video data and more specifically to algorithms and techniques for accelerating scaling and filtering operations on digital video data. The hardware is designed so that scaling and filtering operations are combined and performed simultaneously where possible to speed manipulation of the video data. Efficient design of the system allows memory buffers and logic gates to be shared or eliminated to reduce the size, cost and power requirements of the hardware implementation.
