In one embodiment, in order to identify a Boolean function as either a threshold function or a non-threshold function, a determination is first made as to whether the Boolean function satisfies one or more predefined conditions for being a threshold function, where the one or more predefined conditions include a condition that both a positive cofactor and a negative cofactor of the Boolean function are threshold functions. If the one or more predefined conditions are satisfied, a determination is made as to whether weights for the positive and negative cofactors are equal. If the weights for the cofactors are equal, then the Boolean function is determined to be a threshold function. Further, in one embodiment, this threshold function identification process is utilized in a threshold circuit synthesis process. | 09-01-2011 |
