18th International Symposium on VLSI Design and Test, 2014
In this paper, a constant coefficient finite impulse response (FIR) filter design has been proposed for hearing aid application. The major change in the proposed architecture is the use of 4:2 compressors instead of using adders. The 17 order filter for hearing aid has been realized at gate level using Verilog HDL. The architectures have been implemented in UMC 90nm ...
Proceedings DCC'99 Data Compression Conference (Cat. No. PR00096), 1999
Summary form only given. We study the cascading of LZ variants to Huffman coding for multilingual documents. Two models are proposed: the static model and the adaptive (dynamic) model. The static model makes use of the dictionary generated by the LZW algorithm in Chinese dictionary-based Huffman compression to achieve better performance. The dynamic model is an extension of the static ...

In this paper, a constant coefficient finite impulse response (FIR) filter design has been proposed for hearing aid application. The major change in the proposed architecture is the use of 4:2 compressors instead of using adders. The 17 order filter for hearing aid has been realized at gate level using Verilog HDL. The architectures have been implemented in UMC 90nm technology by the use of Cadence RTL compiler. Synthesis results of the proposed architecture show an improvement of 39.4% and 11.34% in speed and area respectively as compared to the recently published architecture. The proposed architecture provides significant gain of 46.3% in area-delay product (ADP) and 23.7% in power-delay product (PDP). Finally, the functionality of the architecture has been verified by Altera DSP Builder tool.
Summary form only given. We study the cascading of LZ variants to Huffman coding for multilingual documents. Two models are proposed: the static model and the adaptive (dynamic) model. The static model makes use of the dictionary generated by the LZW algorithm in Chinese dictionary-based Huffman compression to achieve better performance. The dynamic model is an extension of the static cascading model. During the insertion of phrases into the dictionary the frequency count of the phrases is updated so that a dynamic Huffman tree with variable length output tokens is obtained. We propose a new method to capture the "LZW dictionary" "by picking up the dictionary entries during decompression. The general idea is the adding of delimiters during the decompression process so that the decompressed files are segmented into phrases that reflect how the LZW compressor makes use of its dictionary phrases to encode the source. The idea of the adaptive cascading model can be thought as an extension of the Chinese LZW compression. Since the size of the header is one important performance bottleneck in the static cascading model we propose the adaptive cascading model to address this issue. The LZW compressor is now outputting not a fixed length token, but a variable length Huffman code from the Huffman tree. It is expected that such a compressor can achieve very good compression performance. In our adaptive cascading model we choose LZW instead of LZSS because the LZW algorithm preserves more information than the LZSS algorithm does. This characteristic is found to be very useful in helping Chinese compressors to attain better performance.
In this paper, an efficient algorithm for concurrent computation of two real multiplications and/or two real additions usually required for high-throughput image and video coding applications is described. The proposed algorithm is mapped onto a novel concurrent dual multiplier-dual adder cell based on carry- save 4:2 compressors. A detailed performance analysis of the the proposed cell shows reductions ranging from 15% to 60% in the computation time and area when compared with the conventional processing elements making it highly attractive for VLSI implementation.
This paper presents an algorithm-level interpretation of fast adder structures in binary/multiple-valued logic. The key idea is to employ a unified representation of addition algorithms called Counter Tree Diagrams (CTDs). The use of CTDs makes it possible to represent various addition algorithms for any positional number system. In this paper, we introduce an extension of CTDs for representing possible fast addition algorithms with redundant number systems. Using the extended version of CTDs, we can classify the conventional fast adder structures including those using emerging multiple-valued logic devices into three types in a systematic way.
A high efficiency, high power magnicon to operate at 34.272 GHz has been designed and built as a microwave source to develop RF technology for a future multi-TeV electron-positron linear collider. To develop this technology, it is necessary to test accelerating structures, RF pulse compressors, RF components, and to determine limits from breakdown and metal fatigue. The tube is designed to provide a peak output power of /spl sim/45 MW in a 1 microsecond pulse, with a gain of 55 dB, using a 500 kV, 220 A, 1 mm-diameter electron beam. The status of the tube itself as well as the near-term experimental program is presented.
A statistical approach to improve the performance of air conditioning system with taking into account the current changeable climatic conditions has been proposed. According to this methodological approach the optimum designed heat load, matching current changeable climatic conditions and providing efficient performance of air conditioning system with maximum annual refrigeration effect, has been defined as a result of statistical treatment of data sets of hourly refrigeration outputs year round. According to this approach a value of optimum designed total heat load on the air conditioning system and corresponding refrigeration capacity of refrigeration machine providing the maximum annual refrigeration capacity output and a value of stable heat load (corresponding refrigeration capacity) as designed basic heat load covered with high efficiency performance of refrigeration machine in nominal mode are calculated. The values of unstable heat loads as boost loads for ambient air precooling covered with low efficiency performance of refrigeration machine in partial modes that cause energetic losses are calculated by remainder principle - as difference between optimum designed total refrigeration capacity, providing the maximum annual refrigeration output, and a value of stable heat load as designed basic heat load. The operation of refrigeration machine in partial modes needs application of energy conserving methods of air conditioning as an example with accumulation of excessive refrigeration capacity at decreased current heat loads and its using at increased current heat loads or application of expensive inventor compressors to control motor speed matching current changeable heat loads.
The authors consider the aliasing probability in multiple-input data compressors used in self-testing networks. It is shown that a far more general class of linear machines, linear-feedback shift registers can be used for data-compression purposes. The steady-state value of the aliasing probability is independent of the correlation of the data streams at the inputs of the data compressor. The function of these machines is modeled by a Markov process. The aliasing probability is the same as for the well-understood signature analysis registers with a single input. An easy-to-check criterion is given to decide whether a given linear machine falls into this class of multiple-input data compressors. Two special kinds of circuits are analyzed in more detail with respect to their aliasing properties: linear-feedback shift registers with multiple inputs and linear cellular automata. Simulation results show the effect of the next state function on the steady-state value of the aliasing probability and the effect of correlation on the transient.<<ETX>>
