Correlator IP Core

The function of this core is to correlate an incoming data stream to a stored binary pattern called a code sequence or coefficient sequence. The data stream may be binary or multi-valued, either signed or unsigned, and is provided to the core one sample at a time. The core can be configured to perform either a real correlation with a single data input stream and a single coefficient sequence, or a complex correlation with two input data streams representing the real and imaginary input terms, and two coefficient sequences representing the real and imaginary coefficients. The core provides multiple channel capability and can support up to 256 channels. Correlations for each channel operate independently from each other. Also, up to 256 different coefficient sequences may be stored in the core, and each channel can select which coefficient sequence is correlated to that channel, so one coefficient sequence could be used for all 256 channels if desired.
