Research Proposal:

1. Research Proposal: A Teaching Laboratory for Real-Time Digital Signal Processing, based on the Freescale MSC711xEVM Principal Investigator: Patrick Gaydecki Co-Applicant: Bosco Fernandes School of Electrical and Electronic Engineering University of Manchester PO Box 88 Manchester M60 1QD United Kingdom Tel: [UK-44] (0) 161 306 4906 patrick.gaydecki@manchester.ac.uk bosco.t.fernandes@manchester.ac.uk www.sisp.manchester.ac.uk/dsp.shtml

2. History of the University The combined university can trace its origins back to 1824 when the Manchester Mechanics' Institute (which later became UMIST) was founded, with Victoria University being founded as Owens College in 1851. The new university has the largest number of full time students of any university in the UK (35,546), unless the University of London is counted as a single university. It also teaches more academic subjects than any other British University. The combined university counts over 20 Nobel Prize winners amongst its former staff and students. It has traditionally been particularly strong in the sciences, with the nuclear nature of the atom being discovered at Manchester, and the world's first programmable electronic computer coming into being here. Famous scientists associated with the university include Niels Bohr, Ernest Rutherford and Alan Turing. However, the university has also contributed in many other fields, and the mathematician Paul Erdős, the author Anthony Burgess and the philosopher Ludwig Wittgenstein all attended Manchester.

3. University Resources • Manchester has the largest income of all UK universities, standing at £514 million as of 2004. In addition, the University has embarked on the largest programme of capital investment ever seen in British higher education with a £350 million plan to deliver eight new buildings and 15 major refurbishment projects by 2010. • Top Ten UK Universities by Research Income (2003/04): • The University of Cambridge £254.2m • The University of Oxford £248.7m • Imperial College £241.6m • University College London £239.2m • The University of Manchester £173.7m • The University of Edinburgh £142.2m • King's College London £140m • The University of Southampton £111.3m • The University of Leeds £107.7m • The University of Sheffield £105m

4. The School of Electrical and Electronic Engineering We are one of the largest schools of this discipline in the UK, and home to a full range of activities within the spectrum of electrical and electronic engineering. In November 2001, the School received full accreditation for its undergraduate programmes (with the maximum score in all of the assessment categories) from the (then) Institution of Electrical Engineers (IEE). Only a matter of months later, it received a Grade 5 in the Research Assessment Exercise. These two external appraisals confirm us as one of the UK's leading Schools of Electrical and Electronic Engineering for both teaching and research. The great breadth and depth of the research interests of our academic staff ensures a very high standard of lecture courses and provides excellent opportunities for challenging and stimulating projects. Our graduates are highly sought after by employers. Independent surveys on employability consistently show our graduates to be the first choice of employers.

5. The School of Electrical and Electronic Engineering: Profile • 58 Academic staff • 67 Contract research staff • 50 Support staff • 428 Undergraduate students • 202 Postgraduate and research students

6. The School of Electrical and Electronic Engineering: Undergraduate Programmes • The undergraduate degree programmes offered by the School provide a comprehensive foundation in the core topics of Electrical and Electronic Engineering coupled with an area of specialism relevant to emerging engineering challenges. • We offer the following programme titles: • Computing and Communication Systems Engineering • Electronic Systems Engineering • Electrical and Electronic Engineering • Mechatronic Engineering • Computer Systems Engineering • Each of these can be studied at BEng or MEng Honours levels. All our degree programmes can be combined with an accredited year-long industrial placement for the award of a With Industrial Experience degree. • DSP is taught in the 3rd and 4th years to most programmes and typically attracts 70 students.

7. The School of Electrical and Electronic Engineering: Postgraduate Programmes The School offers a wide range of postgraduate study opportunities, both full- and part-time, which lead to the degrees of MSc, MPhil, PhD and EngD, or to a Diploma. The MSc requires satisfactory completion of examined lecture courses and dissertation on a short project. The MPhil, PhD and EngD are research degrees although some lecture course material may be included in the programme. Diploma courses are taught courses, and are usually a subset of an MSc programme. DSP is taught as an option module on the Communications Engineering MSc and the Electronic Instrumentation Systems MSc, typically attracting 65 students.

8. The School of Electrical and Electronic Engineering: Research Groups • The University of Manchester is a specialist research-led university linking fundamental research with developments in industry and commerce. The School of Electrical and Electronic Engineering is fully committed to this principle. Our research groups are as follows: • Microwave and Communication Systems • Control Systems • Sensing, Imaging and Signal Processing • Electrical Energy and Power Systems • Power Conversion • Microelectronics and Nanostructures

9. The School of Electrical and Electronic Engineering: Digital Signal Processing Sub-Group • Present Activities include: • Design of real-time audio-bandwidth DSP systems (Signal Wizard) • Real-time magnetic imaging systems • Inductive scan imaging systems • Autonomous ultrasonic sensors for flood detection in oil-rig cross beams • Electromyography for muscular fatigue monitoring • DSP design for the Square Kilometre Array (SKA) radio telescope

10. Introduction: The Proposal This proposal concerns the development of a comprehensive teaching laboratory package for real-time digital signal processing (DSP), targeted towards both undergraduate and postgraduate students. The emphasis will be placed on the real-time nature of DSP, and to facilitate this, a suitable Freescale Evaluation Module (EVM), the MSC711xEVM, will be employed. The laboratory package will represent a complete and thorough introduction to the science of real-time DSP; other than the systems supplied in the package, no other hardware or DSP software will be required. The rationale will be to educate the user by minimizing the time required to install, configure and experiment with the equipment. The host laboratory need only supply, for each workstation area, a computer, function generator, oscilloscope and audio source/output facilities.

11. The Package The package will comprise five major components: Freescale MSC711xEVM, together with the CodeWarrior Software Suite of example programs, to accompany the tutorial exercises Full documentation for getting started and step-by-step tutorial exercises Windows-based user interface for the design and execution of arbitrary complexity DSP routines Accompanying website, containing both teaching material and control software

12. Freescale MSC711xEVM The MSC711xEVM was selected as the target platform since it is both cost effective and based on the high-performance StarCore Architecture. Since the board is supplied with multiple interfaces including JTAG, parallel support, serial interface, 16-bit dual channel codec and Ethernet port, ample scope is provided for the development and experimentation of DSP algorithms that exploit these systems.

13. Documentation: Introduction • The documentation will include a complete introduction to the system, step-by-step instructions for getting started, and a set of tutorial exercises for program development. The student will be taught how to program in SC140 assembly code, C code and mixed-code formats. • In the first instance, the documentation will take the student through a “Getting Started Phase”: • System requirements • Powering up the system • Connecting peripherals: audio source inputs and outputs, function generator and oscilloscope • Starting up Code warrior and downloading supplied test codes: • Test programs: • Audio In/Out • Lissajou figures • Pulsing

14. Documentation: Exercises The documentation will describe laboratory exercises, organized in four major stages: • Stage 2: Intermediate C-code programs (to be developed by the student): • Gain • Mixing • Pulsing • FIR filtering • IIR filtering • Adaptive Filtering • Stage 1: Simple assembly-code programs (to be developed by the student): • Gain • Mixing • Pulsing • FIR filtering • IIR filtering • Stage 3: Advanced C-code programs (to be developed by the student): • Fourier transform and spectral analysis • Hilbert transform • Quadrature Signal Processing • Envelope detection • Sine wave synthesis • Tone generation • Modulation, encoding and decoding • Vocoders • Stage 4: Communication C-code programs (to be developed by the student): • Stand-alone boot mode • Interfacing through the serial port • Interfacing through the parallel port • JTAG • Ethernet • Codec support

15. Tutorial Programme Suite Answers to the programming exercises will be supplied as fully working programs on an accompanying CD. These programs will be complete, stand-alone and ready to run modules, in both source and object code format. Instructions will be given for their assembly (or compilation), downloading and execution. • Intermediate C-code programs: • Gain • Mixing • Pulsing • FIR filtering • IIR filtering • Adaptive Filtering • Simple assembly-code programs: • Gain • Mixing • Pulsing • FIR filtering • IIR filtering • Advanced C-code programs: • Fourier transform and spectral analysis • Hilbert transform • Quadrature Signal Processing • Envelope detection • Sine wave synthesis • Tone generation • Modulation, encoding and decoding • Vocoders • Communication C-code programs: • Stand-alone boot mode • Interfacing through the serial port • Interfacing through the parallel port • JTAG • Ethernet • Codec support

16. Windows-Based User Interface During the period of the research grant, a sophisticated and flexible user interface will be produced. This will allow the student or user of the EVM to specify a chain of DSP operations by dragging and connecting appropriate icons within a design window. Once the design is complete, the software will generate the associated C code as a text file, which may then be opened within the CodeWarrior environment, compiled and downloaded. In concept, this user interface will not be unlike other such systems, such as Simulink; however, it will be optimised for the MSC711xEVMs and will not require MatLab or any other third party software, other than the CodeWarrior environment. It will provide a very broad range of DSP functions, enabling the operator to quickly evaluate a particular algorithm. As such, it will be attractive not merely as a teaching aid, but to professional DSP system designers.

17. Windows-Based User Interface

18. Website A dedicated website will be created as a specific accompaniment to the real-time teaching laboratory. It will include white papers on DSP theory, algorithms, downloadable working programs and hardware design, the latter focused on the StarCore family of processors. Much of the content, in a different format, has already been produced by the applicant as part of his book “Foundations of Digital Signal Processing: theory, Algorithms and Hardware Design”. In addition to the teaching material, the website will include real-time DSP and control software which will communicate to the EVM via its Ethernet port. In this manner, the student will become familiar with internet-based control and communication systems.

19. Summary The Real Time DSP teaching Laboratory represents a complete, highly integrated approach to practical training in this key discipline. Should the proposal be funded, the University of Manchester now plans to be the first to deploy it within its rapidly expanding undergraduate and postgraduate DSP teaching programme areas. With appropriate marketing, the 5-stage package will be seen as an indispensable aid to the teaching of DSP in many universities and higher educational establishments. In addition, it is anticipated that the Windows-based user interface will be a highly marketable product in its own right, attractive to both the educational and professional development markets.

20. Resources Requested It is anticipated that this research program will require 12 man-months to complete, with 100% effort on the part of the researcher. Resources are therefore requested for the associated salary. In addition, UK universities now apply Full Economic Costs (formerly overheads). With respect to equipment support, resources are requested to purchase the necessary EVM hardware and a PC dedicated to the project. Finally, funding is requested to meet travel and subsistence costs in relation to presentation of results at suitable conferences.
