Design of control devices for distributed power management ; Conception de dispositifs de contrôle asynchrones et distribués pour la gestion de l'énergie

Today integrated systems are increasingly faced with the constraints of low consumption or energy efficiency. These issues need to be integrated as far upstream as possible in the design flow to reduce design time and avoid much iteration in the flow. In this context, the collaborative project HiCool, between LIRMM and TIMA laboratories, Defacto, Docea and ST Microelectronics companies, has set up a strategy and design flow to design integrated low power systems while facilitating the reuse of existing hardware blocks (IPs). The approach proposed in this thesis fits into this strategy by bringing a small dose of asynchrony in completely synchronous systems. Indeed, the reduction in consumption is based on the observation that permanent activation of the entire circuit is unnecessary in many cases. However, controlling the activity with techniques of clock gating" or "power gating" usually need to perform a re-design of the system and to add a control device for controlling activation of areas effecting treatment. The work presented in this manuscript provides a strategy based clock controllers and power domain, asynchronous, distributed and easily insertable into a circuit with a low cost design..
