The Intersil HSP45256 is a high-speed, 256 tap binary correlator. It can be configured to perform one-dimensional or two-dimensional correlations of selectable data precision and length. Multiple HSP45256’s can be cascaded for increased correlation length. Unused taps can be masked out for reduced correlation length.
