Abstract

The floating point number data processing means is for use in microprocessor systems and finds application in AC motor drive technology.The format used includes a sign bit, a seven bit signed exponent and an eight bit mantissa.The mathematical functions are performed in a gate array using registers which are mapped into a memory of the microprocessor system, the particular mathematical function being dependent upon a particular choice of registers. An unsigned integer comparison of floating point numbers is used to give a correct result.
