Preface
Practising digital signal processing and digital system design for many years, and introducing and then developing the contents of courses at undergraduate and graduate levels, tempted me to write a book that would cover the entire spectrum of digital design from the signal processing perspective. The objective was to develop the contents such that a student, after taking the course, would be productive in an industrial setting in different roles. He or she could be a good algorithm developer, a digital designer and a verification engineer. An associated website (www.drshoabkhan.com) hosts RTL Verilog code of the examples in the book. Readers can also download PDF files of Microsoft PowerPoint presentations of lectures covering the material in the book. The lab exercises are provided for teachers’ support.
The contents of this book show how to code algorithms in high-level languages in a way that facilitates their subsequent mapping on hardware-specific platforms. The book covers issues in implementing algorithms using fixed-point format. The ultimate conversion of algorithms developed in double-precision floating-point format to fixed-point is a critical design stage in system implementation. The conversion not only requires simple translation but in many cases also requires the designer to explore other structural options for mitigating quantization effects of fixed-point implementation. A number of commercially available system design and simulation tools provide support ...
