Abstract:
1. A method for providing a memory bandwidth efficient (cross) correlation acceleration, said method comprising: generating a plurality of shifted versions with respect to an input signal data sequence for each column of a sliding window associated with a correlator in order to reduce an input bandwidth requirement; multiplying concurrently said input signal data sequence and said plurality of shifted versions with a reference signal data sequence and summing a multiplication result with respect to each column of said sliding window in order to generate an output signal data profile; and storing said output signal data profile into an accumulator register of an array of accumulators that acts as adders for summing an output data signal profile of said each column in said sliding window of said correlator in order to reduce an output bandwidth requirement and thereby provide a memory bandwidth efficient correlation acceleration across a wide range of wireless communication systems.
