Abstract—In this paper we address the problem of the archi-tectural exploration from the energy/performance point of view of a VLIW processor for embedded systems. We also consider an architectural modification we introduced in order to extend the reference processor so that it can exploit both

Instruction Level Parallelism (ILP) extraction for multi-cluster VLIW processors is a very hard task. In this paper, we propose a retargetable architecture that can exploit ILP and thread level parallelism jointly, thus allowing an eas-ier parallelism extraction and improving the performance

Abstract — Interleaved multithreading is a technique in which the processor starts executing a different task when the current thread is stalled. However, whereas different forms of hardware multithreading have been extensively evaluated in superscalar processors, an evaluation of multithreading

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable

Massively multiplayer online games (MMOGs) have become increasingly popular in the recent years, particularly in the form of online role-playing games (MMORPGs). These games support up to several ten thousand players interacting in a virtual game world. The current commercially successful games

ii iv vTo my parents vi vii Acknowledgements I would first and foremost extend my whole-hearted gratitude to my advisors, An-drea Arpaci-Dusseau and Remzi Arpaci-Dusseau. Andrea and Remzi are the reason that I had the opportunity for this exceptional Ph.D. journey. To this day, I still re-member the moment when they took me as their student and the joy and hope in my heart. Andrea and Remzi have showed me what systems research is like and how much fun and challenging it can be. Before this journey with them, I had always liked and believed in the beauty of mathematics and theory. My initial interest in systems research happened when I took Remzi’s Advanced Operating Systems
