Digital Signal Processing Case Study Taghizadehgh

Real-Time Digital Signal Processing

These resources introduce real-time digital signal processing (DSP) applications, algorithms and hardware. They aim to bridge the mathematics introduced in an undergraduate DSP course with practical implementation issues. The interaction between hardware and software are studied in the context of the TMS320DM6437 (DaVinci Video Processor) using MATLAB/Simulink. Case studies involving real-time filter design and the implementation of common real-time audio, image and video processing algorithms are explored.


 

Learning Outcomes and Objectives

The notes, assignments and labs/demos on this page are developed, in part, for a course with the following learning outcomes and objectives.

It is the intent that students will:

  1. Be able to identify the basic architectural elements of DSP hardware;
  2. Understand common real-time DSP algorithms for filtering and multimedia processing applications;
  3. Be able to program DSP hardware to perform signal, image and video processing tasks using MATLAB/Simulink;
  4. Gain an appreciation for the trade-offs necessary in algorithm design for real-time DSP implementation;
  5. Be able to overcome technical obstacles through ingenuity and resourcefulness; and
  6. Acquire an appreciation of the importance of real-time DSP for a broad class of engineering applications.

Digital Signal Processing: A Review Journal is one of the oldest and most established journals in the field of signal processing yet it aims to be the most innovative. The Journal invites top quality research articles at the frontiers of research in all aspects of signal processing. Our objective is to provide a platform for the publication of ground-breaking research in signal processing with both academic and industrial appeal.

The journal has a special emphasis on statistical signal processing methodology such as Bayesian signal processing, and encourages articles on emerging applications of signal processing such as:

• big data• machine learning• internet of things• information security• systems biology and computational biology,• financial time series analysis,• autonomous vehicles,• quantum computing,• neuromorphic engineering,• human-computer interaction and intelligent user interfaces,• environmental signal processing,• geophysical signal processing including seismic signal processing,• chemioinformatics and bioinformatics,• audio, visual and performance arts,• disaster management and prevention,• renewable energy,

We welcome also submissions in the fundamental areas such as information theory and on mathematical topics with potential applications in signal processing such as functional analysis, stochastic calculus, game theory and group theory. Papers in the classical application areas of signal processing such as telecommunications, speech, image and video processing are welcome only if they contain novel research into methodology.. Purely application oriented articles in these areas should be submitted to the relevant dedicated journals

Digital Signal Processing: A Review Journal also aims to publish quality review articles in addition to occasional focus issues with special emphasis on emerging topics. Discussion articles in which several leading researchers discuss the future of a specific research area are also welcome.
