  3. 2. Hardware Implementation of a 32-point Radix-2 FFT Architecture

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ying Gao; [2015]
    Nyckelord :Radix- 2 FFT; Hardware Implementation; synthesis; place route; prime time; power consumption; Technology and Engineering;

    Sammanfattning : The Fast Fourier Transform (FFT) algorithm has been widely used in the Digital Signal Processing industry as a rudimentary operation to select the specific frequency components of a signal, which has been involved with other time domain signals. In order to fulfill the requirements of executing precise calculations and less power & area consumption, an algorithm with less number of adders and multipliers is used. LÄS MER

  4. 3. BENCHMARK OF TRIGGERED INSTRUCTION BASED COARSE GRAINED RECONFIGURABLE ARCHITECTURE FOR RADIO BASE STATION

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Yu Yang; [2014]
    Nyckelord :;

    Sammanfattning : Spatially-programmed architectures such as FPGA are among the most prevailing hardware in various application areas. However FPGA suffers from great overheads such as area, latency and power efficiency. Coarse-grained Reconfigurable Architecture (CGRA) is designed in order to compensate these disadvantages of FPGA.

  5. 4. Modeling and algorithm adaptation for a novel parallel DSP processor

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Olof Kraigher; Johan Olsson; [2009]
    Nyckelord :DSP; FFT; Parallell; Simulator; P3RMA; SIMD;

    Sammanfattning : The P3RMA (Programmable, Parallel, and Predictable Random Memory Access) processor, currently being developed at Linköping University Sweden, is an attempt to solve the problems of parallel computing by utilizing a parallel memory subsystem and splitting the complexity of address computations with the complexity of data computations. It is targeted at embedded low power low cost computing for mobile phones, handsets and basestations among many others. LÄS MER
