Description
Summary:This paper presents an enhanced template matching algorithm and its chip implementation. The proposed algorithm called the enhanced moment preserving pattern matching (EMPPM) improves the noise margin by 22% compared with the previously proposed algorithm called the moment preserving pattern matching (MPPM) algorithm. In addition, the proposed architecture can reduce the gate count by more than 28% compared with the MPPM architecture. We have implemented behavior and structure models using VHDL and performed logic synthesis using the Synopsys/sup TM/ CAD tool. The actual chip has been implemented using the Samsung/sup TM/ 0.6 /spl mu/m SOG (sea-of-gate) cell library. The implemented chip consists of 35,827 gates, operates at 100 MHz and performs 16/spl times/16 template matching with a speed of 200 Mpixels/s.
