Outline

The M65727 is a highly efficient motion estimation LSI used to estimate motion vectors for real-time encoding of dynamic images. M65727 can be used together with the frame memory, the M65721 (Controller LSI) and the M65722 (Pixel Processor LSI). It operates under the control of the M65721. M65727 accepts the template macro block (MB) data inputs from the M65721 and accepts the search window image data from the frame memory. It estimate the motion vectors by searching the minimum value of the mean absolute error between template block data and search window image data. It outputs the result to the M65721. The M65721 and the M65722 are able to generate prediction image using the above mentioned motion vector. The M65727 is designed so that it is applicable to MPEG2, the international video compression standard.
