Programmable image transform processor for digital image processing

摘要

A programmable image transform processor has a programmable addressing and arithmetic blocks. In the programmable addressing block, an input address generator has an input addressing microsequencer and an input addressing memory that stores an input addressing procedure. The microsequencer executes the input addressing procedure to generate addresses from which to request image data. In the programmable arithmetic block, an arithmetic block memory stores an image processing procedure and a microsequencer executes the image processing procedure using the image data to generate transformed image data.
