Abstract After the successful introduction of the PCI-based RS/6000 workstations (40P/43P), the RISC System/6000 family of products has been expanded to include a new line of workgroup servers based on the PowerPC microprocessor, the Peripheral Component Interconnect (PCI) and the PowerPC Reference Platform Specification (PReP). These servers, which offer large memory and internal disk capacities, PC I/O compatibility and flexible configurations, use “industry standard” components and subsystems. The configuration flexibility and the enhanced Reliability, Availability and Serviceability (RAS) features provided with the PCI-based RS/6000 servers constitute the substantial difference when these servers are compared to the previously announced PCI-based RS/6000 workstations. To support these new systems, new adapters and devices had to be provided, and the AIX Version 4.1 operating system had to be enhanced dramatically. All these enhancements present new environments and new configuration tasks to system engineers, system administrators and customer engineers. This book is intended to describe this new environment and to assist the support personnel in accomplishing these new tasks.

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.

  • Apple Computer's Financial Performance
    Apple Computer’s Financial Performance Abstract Since its formation in 1976 Apple Computer has been a pioneer in the PC market. Despite its brilliance in design, and the quality of the user experience from its computers, Apple was increasingly challenged by the rise of IBM-compatible machines and the Windows operating system. Following profound crisis in the 1990s, the firm had a renaissance under the leadership of its previously exiled founder, Steve Jobs. Eventually, the runaway success of the iPod and iTunes music products restored the firm’s profitability. This case provides a longitudinal review of Apple’s financial performance. By looking at the financial performance of Apple over a long period, the case shows how a firm’s strategy, its business model and its competitive environment drive its financial performance. The case contains a history of Apple from its creation in 1976 and a detailed financial ratio analysis and cash flow analysis from 1984 to 2007. Over most of its life, Apple’s profitability, and in the nineties, its survival, depended on tight balance sheet management. Apple struggled throughout to achieve the revenues needed to leverage its cost base. This breakthrough eluded John Sculley in the early eighties, but is what the music products finally delivered after 2005. This case was prepared by Professor Chris Higson with assistance from Tom Albrighton. This case updates and extends the earlier cases, Apple (2000, 2006). The case study was prepared in 2008 from publicly available information as a basis for class discussion rather than to illustrate either the effective or ineffective handling of an administrative situation.

  • IBM POWER Microprocessors
    IBM POWER microprocessors IBM has a series of high performance microprocessors called POWER followed by a number designating generation, i.e. POWER1, POWER2, POWER3 and so forth up to the latest POWER9. These processors have been used by IBM in their RS/6000, AS/400, pSeries, iSeries, System p, System i and Power Systems line of servers and supercomputers. They have also been used in data storage devices by IBM and by other server manufacturers like Bull and Hitachi. The name "POWER" was originally presented as an acronym for "Performance Optimization With Enhanced RISC". The POWERn family of processors were developed in the late 1980s and are still in active development nearly 30 years later. In the beginning, they utilized the POWER instruction set architecture (ISA), but that evolved into PowerPC in later generations and then to Power Architecture, so modern POWER processors do not use the POWER ISA, they use the Power ISA. History Early developments The 801 research project Main article: IBM 801 In 1974 IBM started a project to build a telephone switching computer with, for the time, immense computational power. Since the application was comparably simple, this machine would need only to perform I/O, branches, add register-register, move data between registers and memory, and would have no need for special instructions to perform heavy arithmetic. This simple design philosophy, whereby each step of a complex operation is specified explicitly by one machine instruction, and all instructions are required to complete in the same constant time, would later come to be known as RISC. When the telephone switch project was cancelled IBM kept the design for the general purpose processor and named it 801 after building #801 at Thomas J.

  • A Framework to Model and Analyze the WHY and the HOW of Coopetition- Final
    A Framework to Model and Analyze the WHY and the HOW of Coopetition: Application to the Coopetition in the PowerPC Case Arash Golnam Ecole Polytechnique Fédérale de Lausanne School of Computer and Communication Sciences (I&C) Station 14, CH-1015 Lausanne, Switzerland Tel: +41 21 693 67 94 Email: [email protected] Ron Sanchez Department of Innovation and Organizational Economics Copenhagen Business School Kilevej 14A - 3rd Floor DK-2000 Frederiksberg, Denmark Email: [email protected] Alain Wegmann Ecole Polytechnique Fédérale de Lausanne School of Computer and Communication Sciences (I&C) Station 14, CH-1015 Lausanne, Switzerland Tel: +41 21 693 43 81 Email: [email protected] 1 Abstract. Coopetition has been defined as an approach to managing that combines competition and cooperation. IT transcends the traditional paradigms of competition and cooperation in an effort to achieve the advantages of both. As an inter-organizational relationship that is of a higher complexity than either simple competition or cooperation, coopetition presents both conceptual and practical challenges for business managers and researchers in the strategy field. In this paper we present a systemic approach to modeling coopetition between firms that provides a methodology for analyzing the strategic incentives for enterprises to engage in coopetition relationships and the organization design required to address the complexities inherent in such multi-faceted relationships. Our approach comprises a modeling technique called Systemic Enterprise Architecture Method (SEAM) that incorporates important conceptualizations adapted from competence- based management (CBM) theory. We illustrate our approach by applying it to the case coopetition between IBM and Apple in the development of PowerPC CPU.

    A Technical History of Apple’s Operating Systems Amit Singh A Supplementary Document for Chapter 1 from the book Mac OS X Internals: A Systems Approach. Copyright © Amit Singh. All Rights Reserved. Portions Copyright © Pearson Education. Document Version 2.0.1 (July 28, 2006) Latest version available at http://osxbook.com/book/bonus/chapter1/ This page intentionally left blank. Dear Reader This is a supplementary document for Chapter 1 from my book Mac OS X In- ternals: A Systems Approach. A subset (about 30%) of this document ap- pears in the book as the first chapter with the title Origins of Mac OS X. This document is titled A Technical History of Apple’s Operating Systems. Whereas the book’s abridged version covers the history of Mac OS X, this document’s coverage is considerably broader. It encompasses not only Mac OS X and its relevant ancestors, but the various operating systems that Apple has dabbled with since the company’s inception, and many other systems that were direct or indirect sources of inspiration. This was the first chapter I wrote for the book. It was particularly difficult to write in terms of the time and other resources required in researching the mate- rial.
