  • An ultra low power frequency reference for timekeeping applications

    Creator:
    Oporta, Hector Ivan
    Abstract:
    An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...

  • Design of high-performance pipeline analog-to-digital converters in low-voltage processes

    Creator:
    Myers, Charles Grant
    Abstract:
    Pipeline analog-to-digital converters (ADCs) have long been used in high-speed systems for power-efficient data conversion. Broadband communication and video processing systems are placing high demands on converter accuracy and speed (above 14 bits and in the multiple-MHz range). The increasing converter requirements coupled with lower supply voltages in modern processes...

  • Active matrix electroluminescent device power considerations

    Creator:
    Beck, Douglas
    Abstract:
    An active-matrix electroluminescent (AMEL) design tool has been developed for the simulation of AMEL display devices. The AMEL design tool is a software package that simulates AMEL device operation using a lumped parameter circuit model. The lumped parameter circuit model is developed primarily to address AMEL power dissipation issues. The...

  • A resource-constrained scheduling scheme that considers resources operating at multiple voltages and register assignment

    Creator:
    Lee, Chee
    Abstract:
    Power and timing requirements are becoming more and more stringent as applications move from less mobile devices to more mobile ones. As such, it is important to optimize these applications as much as possible in order to provide the best solution that is low power and low latency. Although there...

  • Optimizing performance/watt of embedded SIMD multiprocessors through a priori application guided power scheduling

    Creator:
    Albright, Ryan K.
    Abstract:
    A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...

  • Low power scheduling schemes that consider latency and resource constraints at multiple voltages

    Creator:
    Huang, Shyh-Sen
    Abstract:
    Power reduction can be achieved at many different levels, such as architecture, algorithm, logic, and transistor levels in circuit design. This thesis focuses on low power scheduling at the algorithm level. We present a latency-constrained scheduling and a latency and resource constrained scheduling, which minimize power consumption for the resources...
