To enable students to command the essential principles of digital logic systems as used for control, communications and information processing.

To enable the student to design such systems.

To study the operation and performance of computer arithmetic circuits, synchronous and asynchronous sequential logic circuits.

Outline Of Syllabus

Logic Design and VHDL

Review of techniques for logic design, from discrete logic gates to ASICs; The VHDL language as a tool for digital design; FPGA and PLA architectures.

Arithmetic Circuits

Combinational logic circuits for the parallel adder; carry propagation; carry look-ahead; subtraction; logic functions; the ALU; multiplication and shifting; serial multipliers: parallel and carry save methods.

Sequential Logic Synchronous systems

Finite state machines; state assignment; synthesis of synchronous FSMs; implementation methods; memory and combinational logic; examples of implementation of controllers and algorithms.

Asynchronous systems

Fundamental mode; implementation of a primitive flow table; races; metastability and synchronisation failure.

Assessment Rationale And Relationship

The examination provides opportunity for the student to demonstrate their understanding of the course material. The problem solving aspects of the assessment enable students to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to novel situations. The in-course assessments (problem solving exercises) provide the opportunity for students to demonstrate their abilities under open book conditions.
