Patent ID: 7931190

Claim:
A circuit comprising: a plurality of selection circuits, each of the plurality of selection circuits having a first input, a second input, a control input, and an output, wherein 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 wherein signals are correlated signals when the value of one of the signals affects or influences the value of the other signals, or all of the signals are affected by or influenced by another common signal; and a population count circuit having a plurality of data inputs respectively coupled to receive the outputs of the plurality of selection circuits, the population count circuit providing a population count for the plurality of data inputs.
