Abstract
The disclosed embodiments include an apparatus implemented in a semiconductor integrated chip. The apparatus is configured to operate a composite function, comprising a first function and a second function, on a first patch of an image. The apparatus includes a first function operator configured to operate the first function on the group of pixel values to provide a first processed group of pixel values. The apparatus also includes a delay system configured to maintain the first processed group of pixel values for a predetermined period of time to provide a delayed processed group of pixel values. The apparatus further includes a second function operator configured to operate a second function on at least a second processed group of pixels and the delayed processed group to determine an output of the composite function.
