Gallium arsenide based floating point adder/subtractor

Floating point calculations are critical to modern computer systems. Applications ranging from graphic intensive games to neural network systems rely heavily on the floating point unit, or FPU. Gallium Arsenide (GaAs) is a semiconductor that may one day rival rite stronghold that silicon has on the manufacture of components such as FPU's. Indeed, GaAs technologies are potentially superior to silicon due to their high speed and relatively low power consumption. In this paper, the design of a 32-bit GaAs floating point adder/subtractor is discussed. The basics of floating point representation and the process of addition and subtraction are covered. The design Of an adder/subtractor circuit is layed out. Simulation of completed components provide performance estimates for the entire circuit.
