Floating-point arithmetic operation range exception override circuit

Abstract:

In various embodiments, a floating-point arithmetic circuit includes a range exception detection circuit and an output circuit. The range exception detection circuit may generate a selection signal that indicates whether a floating-point arithmetic result generated within the floating-point arithmetic circuit is within a specified range. The output circuit may output the floating-point arithmetic result in response to the selection signal indicating the floating-point arithmetic result is within a specified range. The output circuit may output a corresponding specified value in response to the selection signal indicating the floating-point arithmetic result is not within the specified range. Accordingly, floating-point arithmetic operations may be performed in combination with an operation that limits a range of an output to a specified range.
