The FELIN arithmetic coprocessor chip
No full textISBN: 0818607742International audienceA description is given of a general VLSI architecture for the computation of arithmetic expressions including floating-point transcendental functions. This architecture is divided in three parts: a communication machine, the control part of a computation machine, and the operative part of this computation machine. In order to compute the most usual transcendental functions, the authors introduce some general algorithms including, as a particular case, the CORDIC scheme. The major architecture goals were regularity, parameterization, and automatic design. The final chip is designed in a two-ALU CMOS technology, and its name is FELIN (fonctions elementaires integrees)
Control part design : application to FELIN arithmetic coprocesso
No full textCe travail présente la conception de la partie contrôle du coprocesseur arithmétique Felin ( fonctions élémentaires intégrées). La démarche suivie repose sur des techniques garantissant les performances du circuit et menant à une génération automatique du dessin des masques. Une description structurée des algorithmes de Felin a permis de maitriser leur complexité. Cette structuration se traduit par une décomposition de la partie contrôlé en trois niveaux d'interprétation. Les trois niveaux sont réalisés à partir d'architectures microprogrammées (Rom et Pla). Selon les contraintes specifiques a chaque niveau, des optimisations fonctionnelles et topologiques ont été introduites, contribuant à l'amélioration des performances du circuit. La modélisation des solutions architecturales retenues, a mené au développement d'un "compilateur à la demande". Il est constitue d'outils générant algorithmiquement le dessin des masques des différents blocs et routages de la partie contrôl

Poverty of stimulus and absence of cause: some questions for Felin and Foss
No full textAbstract:We examine an aspect of the argument of Teppo Felin and Nicolai Foss (‘The Endogenous Origins of Experience, Routines, and Organizational Capabilities: The Poverty of Stimulus’; 2011) where they reject the claim of Geoffrey Hodgson and Thorbjørn Knudsen (‘Darwinism, Causality and the Social Sciences’; 2004) that habits depend crucially on stimuli from the social environment. We argue that while rightly stressing human agency they also create a false dichotomy between agential and environmental factors in the explanation. Felin and Foss create further confusion by hinting – without adequate clarification – at an untenable notion of human agency as an uncaused cause. We raise several questions of clarification for these authors.</jats:p
Organizational routines and cognition: an introduction to empirical an analytical contributions
No full textThis article introduces this special issue on routines. It offers some suggestions as to why the concept of routines is considered central in methodological considerations of capabilities and organizational evolution. The contributors to this special issue propose various analytical tools, and provide some missing pieces from the puzzle related to the prominent role of routines. Issues discussed in the papers include methodological individualism. Routines lie between the individual and the firm levels of analysis because they are enacted by individuals in a social context. It is also suggested that a multilevel research agenda provides a finer grained analysis because organizational routines are not isolated units but are entangled among the various organizational layers.Orgaizational Routines

A scientific method for start-ups: comparing lean and the theory-based view
No full textRecent scholarship has sought to develop a “scientific method” for startups. In this paper we contrast two approaches: lean startup and the theory-based view of startups. The lean startup movement has served an important function in calling for a normative and scientific approach to startups and venture creation. The theory-based view shares this agenda. But there are differences in the underlying theoretical mechanisms and practical prescriptions suggested by each approach. We highlight these differences and their implications for both research and practice. For example, we contrast lean startup’s emphasis on bounded rationality and entrepreneur-customer information asymmetry with the theory-based view’s emphasis on generative rationality and belief asymmetry. The theory-based view focuses on contrarian beliefs, associated problem formulation, and the development of a startup-specific causal logic for experimentation, resource acquisition, and problem solving. The right mix of entrepreneurial actions is contingent and startup-specific—guided by a startup’s unique theory. After pointing out differences between the lean and theory-based view of startups, we discuss opportunities for partial reconciliation, as well as opportunities for empirically comparing perspectives. Overall, we emphasize that a scientific method for startups needs to recognize the importance of contingent, discriminating alignment between entrepreneurial theories and the actions they prescribe (including different types of experimentation and validation, search, and forms of organization)
