|Teaching period(s)||Semester 1|
|Offered by||Department of Computer Science|
|Available as a free choice unit?||Yes|
This course unit aims to reinforce and extend digital hardware development skills which are introduced in the first year. It employs industry-standard tools and languages which are used worldwide for silicon development. The UK has perhaps the strongest expertise in Europe in these areas and skills are in high demand from employers such as ARM and Imagination Technologies who provide much of the digital design for devices such as smartphones and tablet computers.

The module aims to give a view of the role of a digital hardware designer, taking an idea and implementing it as a silicon chip. A processor is a representative example of logic used in today's chips, also giving further insight into how computers actually work.
Having completed the module you should have developed the confidence to be able to take a concept and realise it in hardware. You should also appreciate the test and verification processes involved so that your chips work efficiently and reliably ... first time, every time!
Explain the operation of sequential systems and design and implement systems consisting of datapath and control elements.
Apply design methodologies to aid in the design of complex digital systems.
Discuss key features of the Verilog language and be able to implement sequential digital systems at the register transfer level (RTL) of the design hierarchy.
Explain the design factors of Instruction Set Architectures and discuss the differences between RISC and CISC CPUs, identifying the key functional components and explaining how they work together to execute instructions.
Explain the stages of processor design starting from the Instruction Set Architecture with respect to implementing designs in Verilog.
Discuss approaches for the testing of complex digital designs and apply these to test digital designs implemented in Verilog.
Identify techniques for improving CPU performance including pipelining, superscalar processing and multicore.
Analyse how design factors such as scaling, monetary cost, performance and power consumption impact VLSI designs.
Describe examples of specialised compute units such as coprocessors, floating-point units and vector extensions and identify their relative advantages and disadvantages.
Compare different processor technologies, such as CPU, GPU and FPGA, with respect to different application domains, and discuss future industry trends beyond traditional CMOS scaling.
Reveal important parts of the CAD tool stack including logic synthesis and test as well as placement and routing algorithms.

Direct feedback comes from laboratory work, both from working with the tools themselves and from the staff. Development results can (and should) be observed throughout using simulation and test. Final results are observable with a hardware realisation.
Less formal feedback is available at all times, especially during lectures and laboratory sessions.
