This paper describes the design of a Digital Signal Processing (DSP) system and a set of laboratory experiments to understand and /or teach real time system applications. Digital Signal processors have high performance and in chip integration and are highly suitable for real time control applications. TMS 320C5X is an advanced fixed point DSP processor and is widely used for communication, multimedia and control applications. This paper describes a top down approach for the selection of DSP processor, the hardware board design using TMS320C5X processor, software development using the custom board which can be interfaced with the personal computer (PC). A typical course on this topic starts with an introduction to the DSP chip and then provides a step by step instruction with hands on training using several lab experiments.
Some of the laboratory experiments described here are: FIR filter and IIR filter implementation, word recognition, touch-tone phone dialer and Fuzzy logic based engine control Application of DSP in Automotive control and use of application development tools such as Matlab, Filter design software design packages are also described.
DSP processors are reduced instruction processors optimized for the fastest possible execution of addition, subtraction, multiplication and shifting instructions. DSPs have on- chip multipliers, compute a pipelined running sum of products and perform data scaling, memory shifts and pointer incrementing in parallel with the other operations. Advanced control algorithms requiring very short time loop can be easily implemented using DSPs.
Rapid advances in digital signal microprocessors (DSP) and application specific DSPs are causing enormous impact in the design of real time embedded control systems. Advances in circuit technology, architecture and algorithms, increased speed, availability of fixed point and floating point processors with on-chip DMA ( direct memory access), timer, interconnect ports, pipelined and parallel arithmetic capabilities are contributing to novel applications for DSP chips.
