1. 21. FPGA Implementation of Flexible Interpolators and Decimators

   Master-uppsats, Elektroniksystem; Tekniska högskolan

   Författare :Dabbugottu VenkataVikram; [2013]
   Nyckelord :Interpolation; Decimation; Linear-phase FIR interpolation; VHDL implementation of interpolators and decimators;

   Sammanfattning : The aim of this thesis is to implement flexible interpolators and decimators onField Programmable Gate Array (FPGA). Interpolators and decimators of differentwordlengths (WL) are implemented in VHDL. The Farrow structure is usedfor the realization of the polyphase components of the interpolation/decimationfilters.

3. 22. Design of a Digital Octave Band Filter

   Master-uppsats, Elektroniksystem; Tekniska högskolan

   Författare :Ludvig Lindblom; [2012]
   Nyckelord :Digital filters; multirate filtering; audio processing;

   Sammanfattning : This report describes the design and implementation of a fixed audio equalizer based on a scheme where parts of the signal spectrum are downsampled and treated differently for the purpose of reducing the computational complexity and memory requirements. The primary focus has been on finding a way of taking an equalizer based on a simple minimum-phase FIR filter and transform it to the new type of equalizer. LÄS MER

4. 23. VHDL Implementation of Flexible Frequency-Band Reallocation (FFBR) Network

   Master-uppsats, Institutionen för systemteknik

   Författare :Abrar Hussain Shahid; [2011]
   Nyckelord :20-channel FFBR network; 20-point FFT IFFT; complex multiplier; polyphase components; radix-2; radix-5;

   Sammanfattning : In digital communication systems, satellites give us world wide services. These satellites should effectively use the available bounded frequency spectrum and, therefore, to carry out flexible frequency-band reallocation (FFBR), on-board signal processing implementation on FFBR network is needed.

5. 24. Adaptation of The ePUMA DSP Platform for Coarse Grain Configurability

   Master-uppsats, Datorteknik; Tekniska högskolan

   Författare :Sepehr Pishgah; [2011]
   Nyckelord :Coarse Grain Reconfigurable Hardware; CRA; ePUMA;

   Sammanfattning : Configurable devices have become more and more popularnowadays. This is because they can improve the system performance inmany ways. In this thesis work it is studied how introduction of coarse grain configurability can improve the ePUMA, the low power highspeed DSP platform, in terms ofperformance and power consumption. LÄS MER

7. 25. Understanding Sub-threshold source coupled logic for ultra-low power application

   Master-uppsats, Elektroniksystem

   Författare :Sajib Roy; Md. Murad Kabir Nipun; [2011]
   Nyckelord :STSCL; CMOS-CVL; SCL; PDP; NCL; DFF; FIR; slew rate;

   Sammanfattning : This thesis work primarily focuses on the applicability of sub-threshold source coupled logic (STSCL) for building digital circuits and systems that run at very low voltage and promise to provide desirable performance with excellent energy savings. Sectors like bio-engineering and smart sensors require the energy consumption to be effectively very low for long battery life. LÄS MER
