Computer Architecture and Design
ECE 462 -- Computer Architecture and Design (3 units)
Description: Intended to provide students with an in-depth study of computer architecture and design. Provides a basic knowledge and ability required for understanding and designing standard and novel computer architectures. Topics include; design methodologies at various levels, instruction set design, ALU design, memory organization and design, cache design, virtual memories, interleaved memories, associative memories, control organization and design, hardwired control, micro-programmed control, pipelining, superscalar and super-pipelining, RISC design, vector processing and others.
Grading: Regular grades are awarded for this course: A B C D E.
Usually offered: Fall.
ECE 175, ECE 274, ECE372 or consent of instructor
Computer Architecture: A Quantitative Approach, J. L. Hennessy and D. A. Patterson, Fifth Edition, Morgan Kaufmann Publishers, 2011, and other reading material will be either presented in the class or available as online papers.
Course Learning Outcomes:
By the end of this course, the student will be able to:
- Understand the techniques of quantitative analysis and evaluation of modern computing systems
- Articulate the cost-performance-energy trade-offs and good engineering design
- Design and implement major component subsystems of high performance computers: pipelining, instruction level parallelism, memory hierarchies, input/output, and network-oriented interconnections.
- Undertake a major computing system analysis and design
- Identify the types of parallelism (data, instruction, thread, request – levels) that could be extracted from a given application
- Identify the hardware architecture type (that matches with the program architecture for a given application
- Evaluate the close relation between the instruction set architecture design, datapath design, and algorithm design
- 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
- Quantify and the discuss the design trade-offs involved in warehouse scale computers in terms of cost, energy-efficiency, reliability, and network structure
- Identify the relationship between the programming models, workloads and architectures for warehouse-scale computers (cloud computing)
