ABSTRACT:
An interface circuit performs a last step of an arithmetic operation and a round operation in parallel. The interface circuit includes a first adder circuit that receives as an input a true result of an arithmetic operation in an intermediate format. The first adder circuit outputs both the true result in a final format and a first representable number approximating the true result. A second adder circuit is connected in parallel to the first adder circuit. The second adder circuit receives the true result in the intermediate format and a 1 as inputs. The second adder circuit outputs a second representable number approximating the true result. The interface circuit also includes a selection circuit connected to the outputs of the first and second adder circuits. The selection circuit outputs either the first or second representable numbers as a rounded result of the arithmetic operation.
