11. System Design Includes all hardware components in the system, as well as data processors with the CPU, such as, graphics processing unit and direct memory access – System design also includes: 11/4/2014 Computer Architecture 11 MultiprocessingData Paths Memory Controllers Virtualization

12. Instruction Set Architecture (ISA) Instruction Set Architecture is the embedded programming language of the central processing unit ISA defines the CPU’s functions and abilities based on what programming it can perform – These programs can include the word size, processor register types, memory addressing modes, data formats and the instruction set that programmers use 11/4/2014 Computer Architecture 12

13. Microarchitecture AKA computer organization Microarchitecture defines the paths of data, data processing and storage elements, as well as how they should be put into the ISA 11/4/2014 Computer Architecture 13

14. Structure & Organization Structures: – the static arrangements of parts Organization: – the overall interaction of the computer parts and what they control 11/4/2014 Computer Architecture 14

15. Implementation & Performance Implementation: – the overall design of the computers building blocks Performance: – the behavioral study of the system or of some of its components 11/4/2014 Computer Architecture 15

16. Von Neumann Architecture Von Neumann architecture is the most popular type of computer architecture and is still used by most computers today. It started in 1945 by the mathematician Jon Von Neumann, and it describes the design of an electronic computer with its CPU, which includes the arithmetic logic unit, control unit, registers, memory for data and instructions, an input/output interface and external storage functions https://www.csupomona.edu/~hnriley/www/Von N.html https://www.csupomona.edu/~hnriley/www/Von N.html 11/4/2014 Computer Architecture 16

18. IBM’s Completed Projects Deep Blue – IBM's Deep Blue computer beat the human world chess champion in the year 1997. Now the technology is being applied to other areas. Very Long Instruction Word (VLIW) – The IBM VLIW research project resulted in a hardware prototype, three generations of research compilers, and many publications and patents. ASCI White Blue Pacific – IBM's scalable multiprocessor systems offer many areas of fruitful research. IBM Research recently contributed to the Accelerated Strategic Computing Initiative's White and Blue Pacific supercomputers. 11/4/2014 Computer Architecture 18

19. Summary Computer Architecture is a set of rules that discusses a computer system by talking about its parts and their relations. There are three different categories for computer architecture: System design, instruction set architecture (ISA), and Microarchitecture. There are also four main components such as, structure, organization, implementation, and performance. And the most popular type of computer architecture is Von Neumann Architecture which was started in 1945 by the mathematician Jon Von Neumann. Many modern computer companies work on various projects involving computer architecture today. 11/4/2014 Computer Architecture 19
