Abstract :
A block-matching module for motion compensation is presented. It has been designed for portable H.261-compliant videotelephony applications. The module has digital I/O and adopts analog computation techniques to reduce power consumption below the milliwatt range for QCIF images at 15 frames/s. The area occupied by the computational array is 2.5/spl times/2.5 mm/sup 2/ in double metal, single poly 1.5 /spl mu/m CMOS technology.
