Digital Signal Processing: World Class Designs

Chapter 7. DSP Hardware Options

One of the most confusing aspects of DSP is the fact that the acronym has two meanings: It is used as shorthand for both digital signal processing and digital signal processor. This sometimes leads to the false impression that all signal processing takes places on digital signal processors. In fact, DSP engineers have many other hardware options, and choosing the right hardware platform is an important part of the DSP development process.In this chapter Dake Liu lays out the key DSP hardware options: general-purpose processors (GPPs), DSPs, ASIC, FPGA, and application-specific instruction-set processors (ASIPs). He also explains the implementation issues associated with each option. Liu gives an overview of a ...
