Title: SYSTEM AND METHOD FOR A FLOATING-POINT FORMAT FOR DIGITAL SIGNAL PROCESSORS
Abstract:
An embodiment of a system and method for performing a numerical operation on input data in a hybrid floating-point format includes representing input data as a sign bit, exponent bits, and mantissa bits. The exponent bits are represented as an unsigned integer including an exponent bias, and a signed numerical value of zero is represented as a first reserved combination of the mantissa bits and the exponent bits. Each of all other combinations of the mantissa bits and the exponent bits represents a real finite non-zero number. The mantissa bits are operated on with a "one" bit before a radix point for the all other combinations of the mantissa bits and the exponent bits.
