  • Operating RISC: UNIX Standards in the 1990S
    Operating RISC: UNIX Standards in the 1990s This case was written by Will Mitchell and Paul Kritikos at the University of Michigan. The case is based on public sources. Some figures are based on case-writers' estimates. We appreciate comments from David Girouard, Robert E. Thomas and Michael Wolff. The note "Product Standards and Competitive Advantage" (Mitchell 1992) supplements this case. The latest International Computerquest Corporation analysis of the market for UNIX- based computers landed on three desks on the same morning. Noel Sharp, founder, chief executive officer, chief engineer and chief bottle washer for the Superbly Quick Architecture Workstation Company (SQAWC) in Mountain View, California hoped to see strong growth predicted for the market for systems designed to help architects improve their designs. In New York, Bo Thomas, senior strategist for the UNIX systems division of A Big Computer Company (ABCC), hoped that general commercial markets for UNIX-based computer systems would show strong growth, but feared that the company's traditional mainframe and mini-computer sales would suffer as a result. Airborne in the middle of the Atlantic, Jean-Helmut Morini-Stokes, senior engineer for the UNIX division of European Electronic National Industry (EENI), immediately looked to see if European companies would finally have an impact on the American market for UNIX-based systems. After looking for analysis concerning their own companies, all three managers checked the outlook for the alliances competing to establish a UNIX operating system standard. Although their companies were alike only in being fictional, the three managers faced the same product standards issues. How could they hasten the adoption of a UNIX standard? The market simply would not grow until computer buyers and application software developers could count on operating system stability.

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.

    INFORMATION TO USERS The most advanced technology has been used to photo­ graph and reproduce this manuscript from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are re­ produced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. These are also available as one exposure on a standard 35mm slide or as a 17" x 23" black and white photographic print for an additional charge. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

  • Regional Networks and Industrial Adaptation in Silicon Valley and Route 128
    Regional Networks and Industrial Adaptation Inside-Out: Regional Networks and Industrial Adaptation in Silicon Valley and Route 128 AnnaLee Saxenian University of California, Berkeley Abstract The competitive advantages of regional clusters are the focus of much scholarly and policy attention. The literature relies heavily on the concept of external economies to explain the advantages derived from the spatial clustering of economic activity. This article compares two of America’s leading technology regions—California’s Silicon Valley and Massachusetts’ Route 128, to suggest the limits of the notion of external economies and to propose an alternative network approach to analyzing regional economies. By rejecting the sharp distinction between what occurs inside and outside the firm, the network approach illuminates the complex and historically evolved relations between firms and the social structures and institutions of a par- ticular locality. Through a set of comparisons of companies in Silicon Valley and Route 128, the article explains the divergent performance of these two apparently comparable regional clusters, and in so doing provides insights into the local sources of competitive advantage. The competitive advantages of regional clusters have become a focal point of scholarly and policy attention. The work of Paul Krugman (1991) and Michael Porter (1990) has spurred widespread interest in regions and regional development, once the sole province of economic geographers and regional scientists. These newcomers have ignored an al- ready extensive and sophisticated literature on the dynamics of industrial localization (see, for example, Storper, 1989; Scott, 1988a, 1988b; Vernon, 1960). Yet, like their predecessors, they share a reliance on external economies to explain the advantages of clustering of economic activity.

Kailey Graphics Editor POSIX U.S. DEPARTMENT OF COMMERCE Computer Security Technology Administration National Institute of Standards and Technology Computer Systems Laboratory Software Standards Validation Group Gaithersburg, MD 20899 April 1995 (Supersedes January 1995 issue) U.S. DEPARTMENT OF COMMERCE Ronald H. Brown, Secretary TECHNOLOGY ADMINISTRATION Mary L. Good, Under Secretary for Technology NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY Arab Prabhakar, Director FOREWORD The Validated Products List (VPL) identifies information technology products that have been tested for conformance to Federal Information Processing Standards (FIPS) in accordance with Computer Systems Laboratory (CSL) conformance testing procedures, and have a current validation certificate or registered test report. The VPL also contains information about the organizations, test methods and procedures that support the validation programs for the FIPS identified in this document. The VPL includes computer language processors for programming languages COBOL, Fortran, Ada, Pascal, C, M[UMPS], and database language SQL; computer graphic implementations for GKS, CGM, PHIGS, and Raster Graphics; operating system implementations for POSIX; open systems interconnect implementations for GOSIP; and computer security implementations for DES, MAC and Key Management.
