  • Power efficient H.264 video decoding in embedded multiprocessor

    Creator:
    Kim, Jihong
    Abstract:
    This thesis presents a novel methodology that enables power efficient video decoding in an embedded system based on MPSoC (Multiprocessor System on Chip). This methodology is a physical combination of parallel processing which reduces power consumption of processors by exploiting thread-level parallelism and Dynamic Voltage Frequency Scaling (DVFS) that allows...

  • Analysis and design on low-power multi-Gb/s serial links

    Creator:
    Hu, Kangmin
    Abstract:
    High speed serial links are critical components for addressing the growing demand for I/O bandwidth in next-generation computing applications, such as many-core systems, backplane and optical data communications. Due to continued process scaling and circuit innovations, today's CMOS serial link transceivers can achieve tens of Gb/s per pin. However, most...

  • Simulator for optimizing performance and power of embedded multicore processors

    Creator:
    Goska, Benjamin J.
    Abstract:
    This work presents improvements to a multi-core performance/power simulator. The improvements which include updated power models, voltage scaling aware models, and an application specific benchmark, are done to increase the accuracy of power models under voltage and frequency scaling. Improvements to the simulator enable more accurate design space exploration for...

  • Power efficient analog-to-digital converters using both voltage and time domain information

    Creator:
    Oh, Taehwan
    Abstract:
    As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...

  • Highly digital power efficient techniques for serial links

    Creator:
    Inti, Rajesh
    Abstract:
    Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart from being capable of handling a wide range of data rates, the transceivers should have low power consumption (mW/Gbps) and be fully integrated. This work discusses enabling techniques...

  • Data driven optimization in SAR ADC

    Creator:
    Leung, Jerry
    Abstract:
    Recent publications show that successive approximation register (SAR) analog to digital converters (ADC) are capable of achieving high efficiency over other ADC topologies. Furthermore, techniques have been adopted to process signals with low activity periods, such as biomedical and industrial sensors. Prior work used least- significant bit first quantization (LSBFQ)...

  • Power reduction of MPEG video decoding for mobile multimedia systems

    Creator:
    Lewis, James M.
    Abstract:
    The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the L1 and L2 caches as well as main memory. The heavy load placed...

  • Studying electricity feedback for the home with an emphasis on the user

    Creator:
    Hunter, Josie Elizabeth
    Abstract:
    As non-renewable resources dwindle and costs increase, it becomes ever more important for people to understand and control their electricity usage. Eco-feedback devices are being developed to increase user awareness and reduce consumption. In order for feedback devices to be successfully adopted into the home, however, they must be appealing...

  • TIMR : Time Interleaved Multi Rail

    Creator:
    Ruggeri, Thomas L.
    Abstract:
    This work presents a new energy saving technique for modern digital designs. We propose Time Interleaved Multi-Rail (TIMR) - a method for providing two dynamic supply rails to a circuit. This technique uses the first supply rail to mask the transition delay while changing the voltage of the second rail....

  • A nano-power wake-up circuit for RF energy harvesting wireless sensor networks

    Creator:
    Lindsley, Christopher J.
    Abstract:
    A fully integrated CMOS latched comparator is presented for use as a wake-up circuit that is attached to an RF energy harvester in a battery free wireless sensor network. The system consumes less than 36nA static current at 20°C and dissipates 2pJ of energy per conversion. The comparator comprises of...
