This unit aims to introduce a range of advanced topics in computer architecture, focusing mainly on high performance processors but including recent or hot topics (e.g., low-power design, wide vector units etc.). A student completing the unit should gain an understanding of how most modern processors work. They will also gain an appreciation of how various design decisions can improve quality (according to a metric such as performance, area or power consumption) which extends the output of previous units that focus mainly on functionality. Due to the unit remit, the syllabus is somewhat flexible, and could include:

  • High performance processors: pipelining, hazards, bubbles, branch prediction, delay slots, target buffers, separate instruction units, superscalar, multiple issue, out of order completion, instruction reordering, register renaming, register windows, data parallel execution.
  • Other forms of parallelism: multi-core, multi-threading via SMT and HyperThreading.
  • Application specific processors: graphics processors, neuromorphic processors, stack processors, vector processors, VLIW, DSP, instruction set extensions for multimedia and cryptography.
  • Specific processor designs: x86, Arm, SPARC, MIPS.
  • Selected topics: security, virtualisation, advanced computer arithmetic, bridging the memory gap.

Intended learning outcomes

On successful completion of this unit, students will be able to:

  1. Demonstrate understanding of how modern computer architectures work.
  2. Demonstrate understanding of the issues in high performance processor design.
  3. Appreciate alternative, domain-specific processor design challenges.
  4. Write a simulator, and understood how this differs from almost all other software development tasks.

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures and self-directed exercises.

Assessment Details

50% coursework, 50% summer timed assesment.
