Embodiment Construction

[0009] In the following description, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known circuits, structures, and / or techniques have not been shown in detail in order not to obscure an understanding of this description.

[0010] References to “one embodiment”, “an embodiment”, “example embodiment”, “various embodiments”, etc., indicate that the embodiment(s) of the invention so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment” does not necessarily refer to the same embodiment, although it may.

[0011] In the following description and claims, the terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as s...

Abstract

Efficiency of computation of logarithmic and exponential functions may be improved using multiplication by pre-computed coefficients to obtain intermediate products.

Description

BACKGROUND OF THE INVENTION [0001] In addition to their roles in mathematical libraries, logarithmic and exponential functions (or anti-logarithms) of real numbers play important roles in many applications. For example, in wireless communications, such functions may arise in computing received signal strength indicators (RSSIs), log-likelihood ratios in demodulators and decoders, etc. Further contexts in which they also may arise include speech compression and coding, image contrast enhancement, cryptography and reliability analyses, and digital signal processor (DSP) design. However, many past implementations of these functions have lacked desired speed and / or accuracy.BRIEF DESCRIPTION OF THE DRAWINGS [0002] Various embodiments of the invention will now be described in connection with the associated drawings, in which: [0003]FIGS. 1A and 1B depict flowcharts of computational methods for logarithmic functions according to exemplary embodiments of the invention; [0004]FIG. 2 depicts...
