FAMU-FSU College of Engineering Computer Architecture EEL 4713/5764, Spring 2006 Dr. Michael Frank Module #1 - Introductory Lecture Introductory Lecture Overview of Computer Architecture What’s it all about? Course Administrative Matters Overview of Syllabus, Course Objectives Grading Policies & Procedures First Homework out – Due next Wed. (Time Permitting) Begin Chapter 1 Review of Combinational Logic What’s Computer Architecture? Architecture (in general) = Design of a functional structure Computer Architecture (CA) = Design of the logical structure and functional organization of a computer system. Especially its CPU and associated components Computer Architecture does not traditionally include other aspects of computer system design… Enclosures, styling, packaging, applications, power supplies, cooling systems, peripheral devices… But these are all important in designing real-world products! What is a Computer? Not Just This! A computer is (most generally) any information processing system! Today, this almost always means a digital system… Though simple analog “computers” do exist… Medieval astrolabe Also, today we usually mean a general-purpose, universal, or at least programmable computer Although a wide range of non-programmable digital components exist that perform fixed functions These could be considered simple special-purpose computers Types of Computers In this course, a “computer” could be anything from the simplest embedded microprocessor… …to the largest supercomputer! We will discuss architectural techniques for parallel computing if time permits… Intel 4004 (1971) (4-bit, 740 kHz) IBM Blue Gene/L (2005) (65,536 processors, 136 TFlops, 1MW, 300 tons) Levels of Computer Architecture Computer architects may deal with design elements at a variety of different levels… Custom logic circuit & functional-unit designs. CPU datapath pipelines, memory hierarchies. Instruction-Set Architectures (ISAs) Or other programming models. Special compiler & operating system support. Multiprocessing systems, interconnection networks, distributed systems... Levels of Design & Abstractions Useful Real-World Products Hardware description languages Computer Architecture HW/SW interface } Processor example: Intel Itanium 2 (McKinley) 64b Processor • 221 million transistors! (~US adult population) • How are they used? • What will we do as transistor counts grow? Most of chip is used for memories, inst. decoding, dynamic scheduling… • Why is it done this way? • How much more efficient could it be if more of area went to actual processing?
