Abstract:
A cell for an arithmetic logic unit includes a first input; a second input; a carry-in input; a first control input and a second control input; and a circuit connected to the first input, the second input, the carry-in input, the first control input, and the second control input. The circuit has a first output and a second output, the second output having a first value as a function of the first input and the second input when the first control input and the second control input are supplied values equal to a value at the carry-in input, and having a second value as a function of the first input and second input when the values at the first control input and the second control input are independent of the value at the carry-in input.
