2. Design parameterizable filter using High Level Synthesis
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : As the ASIC designs continue to grow in complexity, traditional RTL level of abstraction is becoming a productivity bottleneck. The RTL design process requires extensive time and effort for verification of algorithmic correctness as well as correct timing and interface behavior. READ MORE

3. LPI waveforms for AESA radar
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.

4. Design and implementation of an approximate full adder and its use in FIR filters
University essay from Elektroniksystem; Tekniska högskolanAbstract : Implementation of the polyphase decomposed FIR filter structure involves two steps; the generation of the partial products and the efficient reduction of the generated partial products. The partial products are generated by a constant multiplication of the filter coefficients with the input data and the reduction of the partial products is done by building a pipelined adder tree using FAs and HAs.

5. FPGA Implementation of Flexible Interpolators and Decimators
University essay from Elektroniksystem; Tekniska högskolanAbstract : 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.
