Introductory Lecture o Overview of Computer Architecture n o What’s it all about? Course Administrative Matters n Overview of Syllabus, Course Objectives o o o Grading Policies & Procedures First Homework out – Due next Wed. (Time Permitting) Begin Chapter 1 n Review of Combinational Logic

What’s Computer Architecture? o Architecture (in general) = n o Design of a functional structure Computer Architecture (CA) = n Design of the logical structure and functional organization of a computer system. o o Especially its CPU and associated components Computer Architecture does not traditionally include other aspects of computer system design… n Enclosures, styling, packaging, applications, power supplies, cooling systems, peripheral devices… o But these are all important in designing real-world products!

What is a Computer? o Not Just This! A computer is (most generally) any information processing system! n Today, this almost always means a digital system… o n Though simple analog “computers” do exist… Medieval astrolabe Also, today we usually mean a general-purpose, universal, or at least programmable computer o Although a wide range of non-programmable digital components exist that perform fixed functions n These could be considered simple special-purpose computers

Types of Computers o o In this course, a “computer” could be anything from the simplest embedded microprocessor… …to the largest supercomputer! n We will discuss architectural techniques for parallel computing if time permits… Intel 4004 (1971) (4 -bit, 740 k. Hz) IBM Blue Gene/L (2005) (65, 536 processors, 136 TFlops, 1 MW, 300 tons)

Levels of Computer Architecture o Computer architects may deal with design elements at a variety of different levels… n n n Custom logic circuit & functional-unit designs. CPU datapath pipelines, memory hierarchies. Instruction-Set Architectures (ISAs) o n n Or other programming models. Special compiler & operating system support. Multiprocessing systems, interconnection networks, distributed systems. . .

Processor example: Intel Itanium 2 (Mc. Kinley) 64 b 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?
