This paper describes the hardware design and implementation of the JAWS (Just Another Watermarking System) embedder and detector for watermarking of realtime uncompressed digital video. Our design employs a floating point datapath, maximizing dynamic range of the FFT, frame filtering, and correlation operations. The design, implemented in a 1.8V, 0.18 /spl mu/m CMOS process with a core area of 3.53 mm/sup 2/, is capable of watermarking video streams at a peak rate of over 3 Mpixels/s.
