Institutional Work as Logics Shift: The case of Intel's Transformation to Platform Leader

In this article, we explore some of the forms of institutional work that organizations perform as they participate externally in the processes that drive change in the institutional logic that characterizes their field, and as they respond internally to the shift as it occurs. More specifically, we present the results of an in-depth case study of Intel Corporation, a firm that was implicated in a fundamental shift in the institutional logic of its field in the late 1980s and 1990s as the field moved from a traditional supply chain logic dominated by computer assemblers to a new platform logic following very different organizing principles. Through the qualitative analysis of 72 interviews with Intel employees, complemented by extensive archival data from 1980 to 2000, we identify two forms of institutional work that Intel performed externally – external practice work and legitimacy work – and two forms of work that they carried out internally – internal practice work and identity work – as the organization worked to simultaneously influence the shift in logic that was occurring and to deal with the ramifications of the shift

Is Innovation King at the Antitrust Agencies? The Intellectual Property Guidelines Five Years Later

The Microsoft antitrust case focused public attention on the role of antitrust enforcement in preserving the forces of innovation in high-technology markets. Traditionally, regulators focused on whether companies artificially hiked prices or reduced output. Now, they're increasingly likely to look first at whether corporate behavior aids or impedes innovation. In this paper, we examine whether innovation has displaced short-term price effects as the focus of antitrust enforcement by the Department of Justice and the Federal Trade Commission and, to the extent that it has, whether enforcement actions are any different as a result. We also ask whether enforcement actions in the area of intellectual property and innovation have been consistent with the 1995 DOJ/FTC Antitrust Guidelines for the Licensing of Intellectual Property [IP Guidelines]. Finally, we consider whether recent enforcement actions identify key areas in which additional guidance from the Agencies would be desirable. We address these questions first in merger cases and then in non-merger cases.

Three-dimensional memory vectorization for high bandwidth media memory systems

Vector processors have good performance, cost and adaptability when targeting multimedia applications. However, for a significant number of media programs, conventional memory configurations fail to deliver enough memory references per cycle to feed the SIMD functional units. This paper addresses the problem of the memory bandwidth. We propose a novel mechanism suitable for 2-dimensional vector architectures and targeted at providing high effective bandwidth for SIMD memory instructions. The basis of this mechanism is the extension of the scope of vectorization at the memory level, so that 3-dimensional memory patterns can be fetched into a second-level register file. By fetching long blocks of data and by reusing 2-dimensional memory streams at this second-level register file, we obtain a significant increase in the effective memory bandwidth. As side benefits, the new 3-dimensional load instructions provide a high robustness to memory latency and a significant reduction of the cache activity, thus reducing power and energy requirements. At the investment of a 50% more area than a regular SIMD register file, we have measured and average speed-up of 13% and the potential for power savings in the L2 cache of a 30%.Peer ReviewedPostprint (published version

Competing through business models

In this article a business model is defined as the firm choices on policies, assets and governance structure of those policies and assets, together with their consequences, be them flexible or rigid. We also provide a way to represent such business models to highlight the dynamic loops and to facilitate understanding interaction with other business models. Furthermore, we develop some tests to evaluate the goodness of a business model both in isolation as well as in interaction with other business models of different organizations, be those competitors, complements, suppliers, partners, etc.Business model; Interaction; Competitive Strategy; Competitive Dynamics;

Using simulations and artificial life algorithms to grow elements of construction

'In nature, shape is cheaper than material', that is a common truth for most of the plants and other living organisms, even though they may not recognize that. In all living forms, shape is more or less directly linked to the influence of force, that was acting upon the organism during its growth. Trees and bones concentrate their material where thy need strength and stiffness, locating the tissue in desired places through the process of self-organization. We can study nature to find solutions to design problems. That’s where inspiration comes from, so we pick a solution already spotted somewhere in the organic world, that closely resembles our design problem, and use it in constructive way. First, examining it, disassembling, sorting out conclusions and ideas discovered, then performing an act of 'reverse engineering' and putting it all together again, in a way that suits our design needs. Very simple ideas copied from nature, produce complexity and exhibit self-organization capabilities, when applied in bigger scale and number. Computer algorithms of simulated artificial life help us to capture them, understand well and use where needed. This investigation is going to follow the question : How can we use methods seen in nature to simulate growth of construction elements? Different ways of extracting ideas from world of biology will be presented, then several techniques of simulated emergence will be demonstrated. Specific focus will be put on topics of computational modelling of natural phenomena, and differences in developmental and non-developmental techniques. Resulting 3D models will be shown and explained

Hardware-Software Co-Design for Fingerprint Biometric Identification

This paper describes the design of a specific architecture for fingerprint identification based on a hardware-software co-design. This work summarizes the main stages involved in a classical fingerprint feature extraction algorithm. The paper proposes a hardware-software partitioning based on a profiler deduced from the execution of the whole algorithm running in a Pentium 1.7 GHz

Enhancing an Embedded Processor Core with a Cryptographic Unit for Performance and Security

We present a set of low-cost architectural enhancements to accelerate the execution of certain arithmetic operations common in cryptographic applications on an extensible embedded processor core. The proposed enhancements are generic in the sense that they can be beneficially applied in almost any RISC processor. We implemented the enhancements in form of a cryptographic unit (CU) that offers the programmer an extended instruction set. The CU features a 128-bit wide register file and datapath, which enables it to process 128-bit words and perform 128-bit loads/stores. We analyze the speed-up factors for some arithmetic operations and public-key cryptographic algorithms obtained through these enhancements. In addition, we evaluate the hardware overhead (i.e. silicon area) of integrating the CU into an embedded RISC processor. Our experimental results show that the proposed architectural enhancements allow for a significant performance gain for both RSA and ECC at the expense of an acceptable increase in silicon area. We also demonstrate that the proposed enhancements facilitate the protection of cryptographic algorithms against certain types of side-channel attacks and present an AES implementation hardened against cache-based attacks as a case study

Data Acquisition Systems for Monitoring and Control of Photovoltaic Generators

none5This paper aims to describe two intelligent systems, microprocessor based, capable of monitoring, both locally o remotely, more photovoltaic strings. In particular, the electronic board called CS097 helps to detect environmental parameters such as temperature and solar radiation and to calculate average power and energy produced by the solar system, in order to monitor the efficiency and electricity production of the photovoltaic field. It can control up to four photovoltaic strings, acquiring voltage and current values for each string. Transducers, installed on the same board, detect currents lower than 20 amps and voltages lower than 1000 V. The acquired data have a maximum error of 1% compared to true current and voltage values generated by the strings. It’s also provided a galvanic isolation between the measuring circuits and the acquisition ones. The CS083 and CS088 electrical boards, instead, work as an alarm system which indicates a critical condition in case of an electrical continuity loss or a not-justified rapid variation of the voltage read on each string.Proceeding of Fourh International Conference on Sensing Technology ICST 2010, Univ.

A System Architecture Approach to Global Product Development

Recent advances in engineering collaboration tools and internet technology have enabled the distribution of product development tasks to offshore sites and global outsourcing partners while still maintaining a tightly connected process. Most firms in complex engineering industries are indeed experimenting with various ways to structure their product development processes on a global basis. In this research, we have explored global product development structures from the perspectives of process flow and system architecture. We employ the design structure matrix method to display and explain these structures and our observations thereof. Through five case studies spanning electronics, equipment, and aerospace industries, we consider the interaction complexity inherent in various global work distribution strategies. We conclude the paper with a summary and directions for future research work
