2013 (English)In: Handbook of Signal Processing Systems / [ed] Shuvra S. Bhattacharyya, Ed F. Deprettere, Rainer Leupers, Jarmo Takala, Springer-Verlag New York, 2013, 2, 593-637 p.Chapter in book (Refereed)
In this chapter fundamentals of arithmetic operations and number representations used in DSP systems are discussed. Different relevant number systems are outlined with a focus on fixed-point representations. Structures for accelerating the carry-propagation of addition are discussed, as well as multi-operand addition. For multiplication, different schemes for generating and accumulating partial products are presented. In addition to that, optimization for constant coefficient multiplication is discussed. Division and square-rooting are also briefly outlined. Furthermore, floating-point arithmetic and the IEEE 754 floating-point arithmetic standard are presented. Finally, some methods for computing elementary functions, e.g., trigonometric functions, are presented.
