Computer Arithmetic (Volumes IIII) collects landmark articles originally published by the IEEE Computer Society Press in 1990. The editor has arranged the articles from fixed point to floating point arithmetic, each explained with a critique to tell the story of the development of modern-day computer design from the founding roots of the design of an arithmetic logic unit (ALU) to its enhancement towards supporting complex computation with the floating point arithmetic. These have made it possible by the advance in Very-large-scale integration (VLSI). Told in the words of the initial developers, this book conveys the excitement of the creators, and the implementations provide insight into the details necessary to realize real chips. The intent of this 3-Volume set is to show progress, evolution, and novelty in the area of computer arithmetic from the design of basic adders, multiplies, divider to floating-point arithmetic. This field has made extraordinary progress since the initial software routines on mainframe computers have evolved into hardware implementations in processors spanning a wide range of performance. Nevertheless, these papers pave the way to the understanding of modern-day processor design where computer arithmetic is supported by floating-point units. As in the original, the book contains many classic papers treating advanced concepts in computer arithmetic, which is suitable as stand-alone textbooks or complementary materials to textbooks on computer arithmetic for graduate students and research professionals interested in the field.
