Abstract :
In this paper we present a novel cross-correlator chip suitable for ¿smart¿ ECG electrodes. Sophisticated QRS-detection is feasible exploring multi-component based cross-correlation and by exploiting the simplicity offered by bitstream processing. The chip is evaluated using real ECG signals as an example application. Power-efficient running cross-correlation is obtained with novel asynchronous circuit solutions consuming only approx. 5 mW. The implemented generic cross-correlator may be explored for other pattern-matching applications in wireless sensor networks or other low-power applications.
