Abstract

This paper describes a course on Digital Signal Processing microcontrollers, DSP microprocessors, DSP specific Field Programmable Gate Arrays, software development tools in embedded system design. This paper also describes a few embedded system applications where DSP plays a significant role.

Introduction

Digital Signal Processing theory, algorithm and applications have experienced a enormous growth in the last three decades. DSP microprocessors are used in many embedded systems from kitchen appliances to aircrafts. This paper describes a course on DSP in Embedded system design. This course emphasizes design of embedded systems using Digital Signal Processing microprocessors, and special DSP FPGA chips. Topics covered include, DSP microprocessor architecture, advanced instructions, addressing modes, interrupt, system design considerations, interfacing serial and parallel I/O, memory structure, arithmetic manipulations, software development tools, multiple DSP processor system design, and embedded system applications. Applications include automotive, multimedia, and wireless communications. Performance measurement, benchmarking and DSP system simulation, testing and debugging. Design of DSP embedded system using Synopsys COSSAP tools. The students will do a set of lab projects and a large embedded system design project.

A list of books and web references used in this course are given in the reference. The course topics are listed below and the time spent on these topics.

1. Introduction to Embedded System hardware, software and selection consideration (2 hr) 2. Quick review of DSP theory: Sampling, aliasing, quantization, fixed point / floating point arithmetics, Convolution, FIR/IIR Filters, DFT, FFT, Z Transform (2hrs)
