IP Data Sheet
Introduction
The function of this core is to correlate an incoming data
stream to a stored binary pattern called a code
sequence or coef?cient 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 con?gured to perform either a
real correlation with a single data input stream and a
single coef?cient sequence, or a complex correlation
with two input data streams representing the real and
imaginary input terms, and two coef?cient sequences
representing the real and imaginary coef?cients.
The core provides multiple channel capability and can
support up to 256 channels. Correlations for each chan-
nel operate independently from each other. Also, up to
256 different coef?cient sequences may be stored in the
core, and each channel can select which coef?cient
sequence is correlated to that channel, so one coef?-
cient sequence could be used for all 256 channels if
desired.
