Abstract
A video motion compensation apparatus comprising an X-read address generation circuit for generating X-read address components in response to a macro block address and an X-motion vector component, a Y-read address generation circuit for generating a Y-read address component in response to a macro slice address and a Y-motion vector component, a write address generation circuit for generating X and Y-write address components in response to the macro slice address and the macro block address, a multiplexing circuit for multiplexing the Y-read address component, the X-read address components and the X and Y-write address components to generate read and write addresses of first and second frame memories, and a data processing circuit for reading video data from a location of one of the first and second frame memories corresponding to the read address from the multiplexing circuit, adding the read video data to inverse discrete cosine transform video data and writing the resultant video data into a location of the other of the first and second frame memories corresponding to the write address from the multiplexing circuit.
