Abstract
A system (10) is provided for performing binary correlation. The system (10) includes a plurality of reference bit registers (12-18). Each reference bit register (12-18) stores a reference bit of a reference sequence. A plurality of sequentially coupled data bit registers (20-26) can sequentially receive and store each data element of an input data stream. At least one programmable delay unit (28, 30) is coupled between sequential data bit registers (20-26). Each programmable delay unit (28, 30) delays at least one data element of the input data stream between the sequential data bit registers (20-26). A plurality of exclusive OR units (32-38) are each coupled to a corresponding reference bit register (12-18) and a corresponding data bit register (20-26). Each exclusive OR unit (32-38) performs an exclusive OR operation between a reference bit stored in the corresponding reference bit register (12-18) and a data element stored in the corresponding data bit register (20-26) in order to generate a resultant bit. A sum unit (40) is coupled to the exclusive OR units. The sum unit (40) sums the resultant bits generated by the exclusive OR units (32-38).
