ECE 462 -- Computer Architecture and Design (3 units)

Description: This course aims to provide a strong foundation for students to understand modern computer system architecture and to apply these insights and principles to future computer designs. It provides basic knowledge, fundamental concepts, design techniques and trade-offs, machine structures, technology factors, software implications, and evaluation methods and tools required for understanding and designing modern computer architectures including multicores, embedded systems, and parallel systems. The course is structured around the three primary building blocks of general-purpose computing systems: processors, memories, and networks.

Grading: Regular grades are awarded for this course: A B C D E

Other reading material will be presented in the class or available as online papers.

Course Learning Outcomes: 

By the end of this course, the student will be able to:

  1. Understand the techniques of quantitative analysis and evaluation of modern computing systems.
  2. Articulate the cost-performance-energy trade-offs and good engineering design.
  3. Design and implement major component subsystems of high performance computers: pipelining, instruction level parallelism, memory hierarchies, input/output, and network-oriented interconnections.
  4. Undertake a major computing system analysis and design.
  5. Identify the types of parallelism (data, instruction, thread, request-levels) that could be extracted from a given application.
  6. Identify the hardware architecture type that matches with the program architecture for a given application.
  7. Evaluate the close relation between the instruction set architecture design, datapath design, and algorithm design.
  8. Evaluate and analyze the state of the art multicore architectures including the datapath and memory subcomponents along with the hardware and software structures enabling cache coherence, dynamic scheduling and out-of-order execution.
  9. Quantify and the discuss the design trade-offs involved in warehouse scale computers in terms of cost, energy-efficiency, reliability, and network structure.
  10. Identify the relationship between the programming models, workloads and architectures for warehouse-scale computers (cloud computing).
