Overview
This course aims to give an understanding of the mechanisms for implementing the programmer's idealised computer. It builds on the introduction to hardware and to simple processors in the Digital Systems course. The Computer Architecture course aims to describe a broad range of architectural designs and to contrast them, highlighting the design decisions they incorporate, and how these design decisions impact program performance.
Practicals
x86/Y86 assembler, pipelined processors, out-of-order execution and program performance, and microcontroller programming
Learning outcomes
By the end of the course, the student should understand the major architectural styles and appreciate the compromises that they encapsulate. They should be able to read outline descriptions of real processors and understand in which way their designs fit into the frameworks described in the course. They should also be able to understand the impact of design choices in programming in the context of a specific architecture.Prerequisites
Students who have not taken Digital Systems will need to do additional background reading on combinational circuts and assembler programming.
