ABSTRACT:
A scheme is provided for processing previous frame data in a motion compensated digital video system to interpolate pixels used in reconstructing a current video frame. Pixel data from a previous video frame is arranged into sub-blocks containing a plurality N of pixels. The sub-blocks are stored in a memory to enable the retrieval of at least one sub-block per memory access cycle. A plurality M of sub-blocks are retrieved from the memory in response to a displacement vector associated with a portion of a current video frame. M is less than or equal to N and the M sub-blocks are retrieved in no more than M memory access cycles. A subset of pixels is chosen from the selected plurality of sub-blocks for use in interpolating pixels for the current video frame portion. The subset of pixels is processed over no more than N memory access cycles to provide N interpolated pixels for the current video frame portion.
