摘要

An image processing circuit for processing a set of transform domain coefficients sequentially in order to produce an image includes a first multiplier stage 205 coupled to receive the set of coefficients 200, for sequentially multiplying each one of the set by a weighting factor to produce a set of weighted coefficients. A second multiplier stage 230 is coupled to receive the set of weighted coefficients for sequentially multiplying each one by a number of transform weighting factors to produce a number of transform weighted coefficients for each one of the set. An accumulator array 240 of elements is coupled to the multiplier. A selection arrangement 270 adds each of the transform weighted coefficients to selected elements of the array according to a selection scheme, such that when the processing of the set is completed, the elements of the array define the image 250.
