HSP45256 Data Sheet May 1999 File Number 2814.4 Binary Correlator 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. The correlation array consists of eight 32-tap stages. These may be cascaded internally to compare 1, 2, 4 or 8-bit input data with a 1-bit reference. Depending on the number of bits in the input data, the length of the correlation can be up to 256, 128, 64, or 32 taps. The HSP45256 can also be configured as two separate correlators with window sizes from 4 by 32 to 1 by 128 each.
