ABSTRACT:
A circuit includes a plurality of selection circuits. Each of the plurality of selection circuits has a first input, a second input, a control input, and an output. Each of the first inputs receives one of a plurality of correlated signals. Each of the second inputs receives one of a plurality of uncorrelated signals. Each of the control inputs receives a correlation mode control signal, and each of the outputs provides the one of the plurality of correlated signals or the one of the plurality of uncorrelated signals based on the correlation mode control signal. The circuit further includes a population count circuit having a plurality of data inputs coupled to receive the outputs of the plurality of selection circuits. The population count circuit provides a population count for the plurality of data inputs. The population count may be an approximate count or an accurate count.
