Abstract
A video decoder system having a scalable IDCT system. Included is a system for determining a complexity level based on a complexity budget inputted from a local resource controller; and an IDCT system that selects a scaling algorithm from a plurality of scaling algorithms, wherein the selected scaling algorithm corresponds to the determined complexity level. Each of the plurality of scaling algorithms provides a unique data-pruning pattern for processing DCT data.
