This book presents recent advances in DSP to simplify, or increase the computational speed of, common signal processing operations. The topics describe clever DSP tricks of the trade not covered in conventional DSP textbooks. This material is practical, real-world, DSP tips and tricks as opposed to the traditional highly-specialized, math-intensive, research subjects directed at industry researchers and university professors. This book goes well beyond the standard DSP fundamentals textbook and presents new, but tried-and-true, clever implementations of digital filter design, spectrum analysis, signal generation, high-speed function approximation, and various other DSP functions.In their NRI square root implementation, three iterations of (25a2) yields results accurate to 32 bits (32-bit mantissa). Texas Instrumentsa#39; document, aTMS320C4x General-Purpose Applications, Usera#39;s Manual, a describes their table lookup NRI square root method where the initial p(0) value is accurate to 8 bits. So they achieve 32 bits of accuracy after only two iterations of (25a2). Chapter 26 Function Approximation Using Polynomials Jyri YlApstalo Nokia Siemens. EDITOR COMMENTS.
