The fundamental operation of cross-correlating signals is viable in a number of signal processing applications. In typical pattern-matching applications, cross-correlation is desirable. In this paper we present a power efficient implementation of a time-domain cross-correlator suitable for integration in CMOS. Bitstream coding of both data and template simplify multiplication operations. Measured...
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...
