  • Energy-Efficient VLSI Architectures for Next
    UNIVERSITY OF CALIFORNIA Los Angeles Energy-Efficient VLSI Architectures for Next- Generation Software-Defined and Cognitive Radios A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Electrical Engineering by Fang-Li Yuan 2014 c Copyright by Fang-Li Yuan 2014 ABSTRACT OF THE DISSERTATION Energy-Efficient VLSI Architectures for Next- Generation Software-Defined and Cognitive Radios by Fang-Li Yuan Doctor of Philosophy in Electrical Engineering University of California, Los Angeles, 2014 Professor Dejan Markovic,´ Chair Dedicated radio hardware is no longer promising as it was in the past. Today, the support of diverse standards dictates more flexible solutions. Software-defined radio (SDR) provides the flexibility by replacing dedicated blocks (i.e. ASICs) with more general processors to adapt to various functions, standards and even allow mutable de- sign changes. However, such replacement generally incurs significant efficiency loss in circuits, hindering its feasibility for energy-constrained devices. The capability of dy- namic and blind spectrum analysis, as featured in the cognitive radio (CR) technology, makes chip implementation even more challenging. This work discusses several design techniques to achieve near-ASIC energy effi- ciency while providing the flexibility required by software-defined and cognitive radios. The algorithm-architecture co-design is used to determine domain-specific dataflow ii structures to achieve the right balance between energy efficiency and flexibility. The flexible instruction-set-architecture (ISA), the multi-scale interconnects, and the multi- core dynamic scheduling are also proposed to reduce the energy overhead. We demon- strate these concepts on two real-time blind classification chips for CR spectrum anal- ysis, as well as a 16-core processor for baseband SDR signal processing.

    Tegra PerfHUD ES 1.1 Quickstart Guide Version 1.1 - 1 - November 2010 Contents INTRODUCTION 3 REQUIREMENTS 4 PERFHUD ES HOST INSTALLATION 5 PERFHUD ES TARGET DEVICE SUPPORT SETUP 6 CONNECTING TO THE TARGET DEVICE 9 COMMON PROBLEMS 11 KNOWN ISSUES 12 November 2010 - 2 - Introduction This quick start guide is designed to assist a new user in setting up and starting PerfHUD ES profiling of applications on a Tegra device. PerfHUD ES enables experimentation and in-depth analysis of OpenGL ES applications. Through data provided by the OpenGL ES driver and the Tegra SoC, developers are provided live system status, including GPU performance and bottleneck information, in order to help target optimizations where they are most needed. The debugging capabilities of PerfHUD ES give full access to the state of the OpenGL ES pipeline, related textures and shaders, and all rendering states to help find the causes for improper setup, rendering anomalies, and performance issues. For the rest of the document, note that all downloads are available on the Tegra Devsite: http://tegradeveloper.nvidia.com/tegra/downloads November 2010 - 3 - Requirements Host PC Ideally, a minimum 2GHz CPU with 2GB RAM or more An OpenGL 1.5 or better GPU (if you have an NVIDIA GeForce 6 series GPU or higher, that should suffice). The ‚PerfHUD ES User Guide‛ installed during this setup process covers specific GPU feature requirements in depth, as certain OpenGL extensions are necessary for the host PC to visualize the graphics rendered on the Tegra device. An available USB port, for flashing your Tegra device, or for Android ADB connection.
