  • 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...

  • Single-level dynamic register caching architecture for high-performance superscalar processors

    Creator:
    Liebert, John A.
    Abstract:
    The amount of instruction level parallelism (ILP) that can be exploited depends greatly on the size of the instruction window and the number of in-flight instructions the processor can support. However, this requires a register file with a large set of physical registers for renaming and multiple ports to provide...

  • Target-based coverage extension of 802.11 MANETs via constrained UAV mobility

    Creator:
    Johnson, Taylor N.
    Abstract:
    MANETs are known to be useful in situations where mobile nodes need to communicate and coordinate in dynamic environments with no access to fixed network infrastructure. However, connectivity problems can occur when sub-groups within a MANET move out of communication range from one another. The increasingly prolific use of UAVs...

  • Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

    Creator:
    Gatimu, Kevin
    Abstract:
    The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

  • Spatial motion vector recovery in wireless high definition video transmission using H.264 over WLANs

    Creator:
    Gatimu, Kevin
    Abstract:
    Mobile devices are becoming more prevalent and complex. As a result, the wireless communication aspect of these devices is becoming increasingly significant. At the same time, video demands in terms of availability and quality are also on the uprise. High definition (HD) video is the standard of choice for meeting...

  • The dynamic speculation and performance prediction of parallel loops

    Creator:
    Zier, David A.
    Abstract:
    General purpose computer systems have seen increased performance potential through the parallel processing capabilities of multicore processors. Yet this potential performance can only be attained through parallel applications, thus forcing software developers to rethink how everyday applications are designed. The most readily form of Thread Level Parallelism (TLP) within any...

  • Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

    Creator:
    Johnson, Taylor N.
    Abstract:
    Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

  • Asymmetric clustering using a register cache

    Creator:
    Morrison, Roger Allen
    Abstract:
    Conventional register files spread porting resources uniformly across all registers. This paper proposes a method called Asymmetric Clustering using a Register Cache (ACRC). ACRC utilizes a fast register cache that concentrates valuable register file ports to the most active registers thereby reducing the total register file area and power consumption....

  • Instruction fetching, scheduling, and forwarding in a dynamic multithreaded processor

    Creator:
    Browning, Adam W.
    Abstract:
    Dynamic multithreaded processors attempt to increase the performance of a single sequential program by dynamically extracting threads from sources such as loop iterations. The scheduling of instructions in such a processor plays a vital role in the amount of thread level parallelism that can be extracted and thus the overall...

    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...
