Number Representation

Conventional and oftentimes exotic methods of number representation can lead to performance gains in terms of simpler and faster circuits. While conventional methods are used extensively, the unconventional ones find application in special purpose digital circuits and systems.

Computer arithmetic deals with the hardware realization of arithmetic functions to support various computer architectures as well as with arithmetic algorithms for firmware or software implementation.

A major thrust of digital computer arithmetic is the design of hardware algorithms and circuits to enhance the speed of numeric operations. Thus computer arithmetic complements the architectural and algorithmic speedup techniques for high-performance computer architecture design and parallel processing.
