  • The IA-32 Processor Architecture
    The IA-32 processor architecture Nicholas FitzRoy-Dale Document Revision: 1 Date: 2006/05/30 22:31:24 [email protected] http://www.cse.unsw.edu.au/∼disy/ Operating Systems and Distributed Systems Group School of Computer Science and Engineering The University of New South Wales UNSW Sydney 2052, Australia 1 Introduction This report discusses the most common instruction set architecture for desktop microprocessors: IA- 32. From a programmer’s perspective, IA-32 has not changed changed significantly since its introduc- tion with the Intel 80386 processor in 1985. IA-32 implementations, however, have undergone dra- matic changes in order to stay competitive with more modern architectures, particularly in the area of instruction-level parallelism. This report discusses the history of IA-32, and then the architectural features of recent IA-32 im- plementations, with particular regard to caching, multiprocessing, and instruction-level parallelism. An archtectural description is not particularly useful in isolation. Therefore, to provide context, each as- pect is compared with analogous features of other architectures, with particular attention paid to the RISC-style ARM processor and the VLIW-inspired Itanium. 2 A brief history of IA-32 IA-32 first appeared with the 80386 processor, but the architecture was by no means completely new. IA-32’s 8-bit predecessor first appeared in the Datapoint 2200 programmable terminal, released in 1971. Under contract to produce a single-chip version of the terminal’s multiple-chip TTL design, Intel’s im- plementation, the 8008, was not included in the terminal. Intel released the chip in 1972.

  • Proceedings of the 1974 Clinic on Library Applications of Data
    DAVID P. WAITE President, Information Dynamics Corporation Reading, Massachusetts The Minicomputer: Its Role in a Nationwide Bibliographic and Information Network In January 1974, Information Dynamics Corporation introduced to the library community a nationwide on-line bibliographic and information net- work called BIBNET. Installations have begun and operations are expected to go into full swing in the summer of 1974. Hardware and software systems being installed at user locations, as well as data entry points, employ mini- computers (see figure 1). This paper will describe the several applications of minicomputers in this large-scale computing network. When BIBNET was first conceived, the decision was made to use minicomputers in order to meet the multipurpose design objectives of a far-reaching nationwide library and information support service. The ultimate objective was not simply the development of a new on-line cataloging system, but the design of a complete service system that would be able to meet successfully future developments in the library community. The network is being established to provide libraries with on-line access to the national data base of machine-readable cataloging records, to provide access to information service modules and for data processing where machine-readable records are available to carry out a number of technical processing operations that in the past have been performed by manual means. Before describing the several system design requirements, it is important to review the basic supporting role and service objectives of the overall bibliographic and information network program. 136 NATIONWIDE BIBLIOGRAPHIC NETWORK 137 This diagram depicts the capabilities of each BIBNET user's terminal regardless of location on North American continent.

MCM was among the first companies to fully recognize and act upon microprocessor technology’s immense potential for developing a new generation of cost-effective computing systems.

  • Oral History Panel on the Development and Promotion of the Intel 8008 Microprocessor
    Oral History Panel on the Development and Promotion of the Intel 8008 Microprocessor Participants: Federico Faggin Hal Feeney Ed Gelbach Ted Hoff Stan Mazor Hank Smith Moderated by: Dave House Recorded: September 21, 2006 Mountain View, California CHM Reference number: X3706.2007 © 2006 Computer History Museum Oral History Panel on Intel 8008 Microprocessor Dave House: Stan, tell us how the 8008 began. Stan Mazor: Well, in today’s personal computers, we have RAM and we have flat panel displays, but in the middle of the ‘60s, we had core memories on our minicomputers and we typically used either a teletype or a CRT terminal (cathode ray tube). We also nicknamed these “glass teletypes” because they played the role of the teletype, but they were much faster. The key ingredient to the CRT terminal in those days was the shift register; there was no RAM memory in those days. Shift register were being provided by General Microelectronics, (GME), General Instrument and some other companies. When Intel got started in 1969 in the memory business, we were designing RAM components-- and we really had no customers for them. So one of the things that we did was---to do a custom order for Datapoint (formerly Computer Terminals Corporation) who was one of the makers of a cathode ray terminal, and we made for them a 512-bit re-circulating shift register. So this gave us a ready customer and it was a type of memory product which was in use at that time. Well, Datapoint, having been in the display [terminal] business, had an idea of going into the business terminal [computer] business; in addition and they had a clever idea, which was to use the shift registers that they were already using inside the display terminal as the main memory of their computer.

  • The CPU and Memory
    The defining component of any computer sys- tem is the central processing unit, or CPU. The design and architecture of the CPU deter- mine what instructions are available for pro- gramming it, how fast it will be able to run, and how data are organized and addressed. The CPU receives data and instructions from memory, performs arithmetic or logical opera- tions on the data, and returns the data to memory. The CPU can perform billions of such operations every second. Even though each op- eration is relatively simple, the CPU can per- form complex actions very quickly by Figure 3-1 combining those relatively simple operations. John von Neumann Los Alamos The first commercially available CPU, that of National Laboratory the UNIVAC I computer delivered to the Census Bureau in 1951,was about 14 feet long, about eight feet wide, and over eight feet tall. By 1970, the progress of Moore’s Law reduced the CPUs of some computers to a single circuit board. In 1971, Intel introduced the first CPU on a chip, intended for use in electronic calculators and incorporating about 2,250 transistors. Modern CPU chips have tens of billions of transistors. In the late 20th century, chips with multiple pro- cessing units were introduced. When a chip has more than one processing unit, the processing units are called cores. Also in the late 20th century, supporting circuitry like memory and bus control- lers began to be added to CPU chips. These evolved to become systems on a chip (SOCs). Today, CPU chips with external supporting circuitry are used where performance is the major factor, such as in servers and workstation com- puters.
