摘要: Since development of the first computing system, there has been a continual quest for faster systems. This is result successful accomplishments with given system which lead to desires do even more, thereby requiring better performance. In many applications, performance requires arithmetic. Recent progress in optical processing suggests that digital arithmetic may eliminate today’s bottlenecks. paper provides an introduction concepts (and literature) The primary emphasis on number systems and algorithms addition, subtraction, multiplication, division, since these operations are basis current
