  • Power Modeling of Embedded Memories
    Carl von Ossietzky Universit¨atOldenburg Fachbereich Informatik Dissertation Power Modeling of Embedded Memories Eike Schmidt March 25, 2003 zur Erlangung des Grades eines Doktors der Ingenieurswissenschaften Gutachter/Supervisor: Professor Dr. Wolfgang Nebel Zweitgutachter/Reviewer: Professor Dr. Norbert Wehn Tag der Disputation: 10. Februar 2003 Synopsys and the Synopsys product names described herein are trademarks of Synospys, Inc. c 2002,2003 by Eike Schmidt To my family Abstract After Moore’s Law the number of transistors on an integrated circuit doubles every 18 months. New circuits are furthermore clocked with increasing frequencies. This development not only leads to an increase of the available functionality, but also to a rise of the electrical power consumption of these systems. The power consumption of integrated circuits is problematic in two respects: on one hand the power must be fed into the system, on the other hand the heat produced on the chip must be dissipated. An increased power consumption consequently leads to reduced battery lifetimes and increased energy costs. Today already 80% of the office related power consumption in the USA stems from computers. The heat development of integrated circuits reduces their reliability and lifetime. The required cooling measures (ceramic packages, heat fins, fans, etc.) furthermore increase the system cost. For the development of low power systems it is necessary to estimate and consider the power consumption already in the early stages of design. For such estimates models of the system blocks are required. This thesis describes a methodology for the generation of models of the power consumption of embedded memories. Memories have a special importance among the system blocks as it is forecast that more than 90% of the area of newly developed systems will be occupied by memory within ten years.

ANÁLISE DOS EFEITOS DE ESCALAMENTO DE TENSÃO NO PROJETO DE CIRCUITOS RESILIENTES RESUMO Embora o avanço da tecnologia de semicondutores permita a fabricação de dis- positivos com atrasos de propagação reduzidos, potencialmente habilitando o aumento da frequência de operação, as variações em processos de fabricação modernos crescem de forma muito agressiva. Para lidar com este problema, significativas margens de atraso de- vem ser adicionadas ao período de sinais de relógio, limitando os ganhos em desempenho e a eficiência energética do circuito. Entre as diversas técnicas exploradas nas últimas dé- cadas para amenizar esta dificuldade, três se destacam como relevantes e promissoras, isoladas ou combinadas: a redução da tensão de alimentação, o uso de projeto assíncrono e arquiteturas resilientes.
