Teaching

Microprocessors for Embedded Computing (BUPT joint programme)

The course examines the structure, applications and programming of microprocessors and their support devices. There will be practical work on using a real hardware processor as part of the module. The course is available only to students on the H6NI BSc (Eng) Internet of Things Engineering programme. The course includes: - Microprocessor / Microcontroller Architecture - Instruction Cycle - Program Development Program Life Cycle - Program Structures - Data Structures - 8051 Microcontroller Overview - Hardware Summary (Memory Map and Register Function) - Instruction Set - Addressing Modes - Assembly Language - Testing and Debugging - Interrupts and Timers - Internal and External Memory: RAM, ROM, EPROM, EEPROM - 8051 ADO Pin Demultiplexing - Von Neumann / Harvard Architecture - Principles of Interfacing - Dedicated I/O Memory Mapped I/O - Address Decoding - Timing Diagrams - Handshaking - Busses - Tri-state logic - Parallel Interfacing - Serial Interfacing - Analogue / Digital Conversion - PWM - Comparators - Polling and Interrupts for Interface Management - 8051 Supporting Hardware - Oscillator and Reset Circuits - Reset Behaviour - LEDs, LCDs, Intelligent Displays - Switches, Keypads / Keyboards - Opto-isolators

Signals and Systems (BUPT joint programme)

This course stresses the appreciation and use of certain transform techniques in the analysis of signals, the related systems and its stability. Emphasis is placed on Fourier methods within the context of continuous time signals and signal processing, Laplace Transform techniques for continuous system stability, and the use of linear difference equations and Z transforms when signals are discrete. The module is taught to students on the H6NI programme of study. The content will allow the student to:Explain fundamental signal analysis concepts. Calculate the parameters of the Fourier series representation of any periodic waveform. Transform time domain signals using the Fourier, Laplace or Z Transforms as appropriate. Calculate the linear difference equation for any linear discrete time system, and explain the difference between FIR and IIR systems. Determine the unit sample response for any linear discrete time system. Determine the transfer function for any linear continuous system and linear discrete time system and discuss stability in this context. Draw the system diagram for certain unit sample responses. Judge the effect of noise on certain signal processing operations.
