Article: TERNARY RECURSIVE FAST TRANSFORMS[Show abstract] [Hide abstract]
ABSTRACT: This paper introduces two new classes of recursive fast transforms over GF (3). They are based on recursive equations using Kronecker products that allows to obtain simple corresponding fast transforms and regular butterfly diagrams. The computational costs to calculate both classes of new transforms and the experimental results comparing introduced transforms with ternary Reed–Muller transform are also presented.Journal of Circuits System and Computers 11/2011; 16(02).

Conference Paper: Logic synthesis strategy for FPGAs with embedded memory blocks[Show abstract] [Hide abstract]
ABSTRACT: With the evolution of programmable structures, that become more heterogeneous, the process of mapping a design into these structures becomes more and more complex. Modern FPGA chips are equipped with embedded memory blocks that can be used to increase the implementation quality of the design. The paper presents a logic synthesis method based on balanced decomposition that uses the concept of r-admissibility to efficiently utilize possibilities provided by memory blocks embedded in modern FPGA architectures. Results presented in this paper prove the effectiveness of proposed approach.Mixed Design of Integrated Circuits & Systems, MIXDES '09. MIXDES-16th International Conference, Lodz, Poland; 06/2009
Conference Paper: Logic synthesis method for pattern matching circuits implementation in FPGA with embedded memories[Show abstract] [Hide abstract]
ABSTRACT: This paper presents a new cost-efficient realization scheme of pattern matching circuits in FPGA structures with embedded memory blocks (EMB). The general idea behind the proposed method is to implement combinational circuits using a net of finite state machines (FSM) instead. The application of functional decomposition method reduces the utilization of resources by implementing FSMs using both EMBs and LUT-based programmable logic blocks available in contemporary FPGAs. Experimental results for the proposed method are also shown. A comparison with another dedicated method yields extremely encouraging results: with a comparable number of EMBs, the number of logic cells has been reduced by 95%.12th IEEE Symposium on Design and Diagnostics of Electronic Circuits and Systems, DDECS 2009, Liberec, Czech Republic; 04/2009
Conference Paper: Fixed Polarity Quaternary Transforms Derived from Linearly Independent Transform over GF(2) Structure.[Show abstract] [Hide abstract]
ABSTRACT: A fixed polarity quaternary linearly independent (FPQLI) transform is introduced in this paper where the basic transforms are derived from the recursive structure of some linearly independent transforms over Galois Field (2) (GF(2)). For some polarities the FPQLI transform for n-variable quaternary functions directly corresponds to the binary fixed polarity Reed-Muller (FPRM) transforms for 2n-variable binary functions. In this paper, the fast flow graph and recursive equations for the FPQLI transform are given together with the underlying basis functions. Formulae for converting the FPQLI spectral coefficient vector from one polarity to another are also given and used to generate a recursive algorithm to obtain the optimal FPQLI expansion with reduced computational cost. Experimental results of the FPQLI transform have been obtained for a set of quaternary test files. Comparison of the obtained results with FPRM over GF(4) as well as the existing recursive quaternary linearly independent transforms show the advantage of applying the concept of fixed polarity to the basic transforms for function minimization in terms of smaller number of nonzero spectral coefficients.ISMVL 2009, 39th International Symposium on Multiple-Valued Logic, 21-23 May 2009, Naha, Okinawaw, Japan; 01/2009

ABSTRACT: This paper presents two novel methods for compression of fluorescent dye cell images. The compression methods achieve high compression ratio by pseudo-quantizing the pixel gray levels according to image statistics and extracting and saving the useful regions of the image. The proposed algorithms produce a better compression over the existing lossless image formats in the case of fluorescent dye cell images and this idea of compression can be further extended to other images.

ABSTRACT: New quaternary linearly independent arithmetic (QLIA) transforms are presented in this paper. The new transforms are recursive and they are classified into two classes according to their recursive equations. Fast flow graphs and relations for the transforms are presented. Computational cost for the calculation of the QLIA spectral coefficient vector is also derived. Experimental results in terms of the minimum number of nonzero spectral coefficients based on the QLIA transforms for a set of quaternary test functions are also given and compared with the corresponding numbers for quaternary fixed polarity arithmetic (QFPA) transforms. The comparison shows that for the set of quaternary test functions the average number of minimum number of nonzero spectral coefficients based on the introduced QLIA transforms is 39.28% and 16.29% smaller than that for the polarity zero and optimal polarity QFPA transforms, respectively.
Conference Paper: Ternary polynomial expansions based on generalized fastest linearly independent arithmetic transforms[Show abstract] [Hide abstract]
ABSTRACT: Spectral expansions are alternative representations of logic functions/signals in which the information are redistributed and presented differently in terms of spectral coefficients. The use of spectral representations often allows certain operations or analysis to be performed more efficiently on the data. In this paper, spectral expansions for ternary functions based on new fastest linearly independent arithmetic transforms are presented and discussed. The new transforms are generalizations of some existing ternary transforms through permutation and reordering operations. They have regular structures and can be computed using fast transforms. Formulae for their fast forward and inverse transformations as well as their corresponding fast flow graphs are shown here. Computational costs and some properties of the transforms and their spectra are also given. Finally, experimental results of the transforms are presented which show that the new transforms can represent some functions more compactly than the existing transforms.Mixed Design of Integrated Circuits and Systems, 2008.

ABSTRACT: This paper presents the discussion on efficiency of different implementation methodologies of DSP algorithms targeted for modern FPGA architectures. Modern programmable structures are equipped with specialized DSP embedded blocks that allow implementing digital signal processing algorithms with use of the methodology known from digital signal processors. On the first place, however, programmable ar-chitectures give the designer the possibility to increase efficiency of designed system by exploitation of parallelism of implemented algorithms. Moreover, it is possible to apply special techniques, such as distributed arithmetic (DA) that will boost the per-formance of designed processing systems. Additionally, application of the functional decomposition based methods, known to be best suited for FPGA structures, allows utilizing possibilities of programmable technology in very high degree. The paper presents results of comparison of different design approaches in this area.07/2008; 20:437-459. DOI:10.2298/FUEE0703437R

Conference Paper: Properties and Computational Algorithm for Fastest Quaternary Linearly Independent Transforms[Show abstract] [Hide abstract]
ABSTRACT: Sixteen fastest quaternary linearly independent (FQLI) transforms are discussed in this paper. All the presented transforms can be derived using recursive equations and their inverse recursive definitions share common structure. In this paper, the fast flow graph equations and properties for the FQLI transforms are given. Based on the relationships between the spectra of the transforms, a recursive algorithm for the computation of their spectral coefficients is also proposed which reduces the total computational cost of generating their complete spectra. Experimental results for all the FQLI transforms as well as fixed polarity Reed-Muller transform over GF(4) are also given and compared in terms of the number of nonzero spectral coefficients. The comparison shows that for some quaternary functions the new FQLI transforms can give more compact representations.Multiple Valued Logic, 2008. ISMVL 2008. 38th International Symposium on; 06/2008

ABSTRACT: High dynamic range (HDR) images require a higher number of bits per color channel than traditional images. This brings about problems to storage and transmission, especially in distributed wireless sensor networks in which transmission capability and energy consumption are critical issues. The paper proposes a structure of compressing multiple dynamic range images, which is called multiple dynamic range (MDR) coding. MDR imaging system is attractive due to the capability of reconstructing lower dynamic range images from partial bitstream. MDR coding shows its advantages in terms of energy efficiency in distributed wireless sensor networks. The efficacy of MDR coding is also illustrated by presenting the results of encoding a series of synthetic and natural MDR images.01/2008; DOI:10.1109/ICSMC.2008.4811745

ABSTRACT: Reliability analysis of a system conducted in the Probabilistic (Arithmetic) domain is lengthy and errorprone. An alternative method is to consider the system reliability components to be Boolean variables rather than Probabilistic variables and to treat the whole problem as if it were Boolean. This method allows the use of powerful Boolean reduction theorems to contain the size of the problem. The Boolean expression should be fully disjoint so that the conversion back to the Probabilistic domain would be on a one-to-one basis. Besides presenting basic properties and definitions of Probabilistic and Boolean domains, evaluation of reliability of a system directly from Arithmetic expansion is also discussed. Since the reliability expression may be directly obtained from disjoint cube representation, two methods are shown.
Article: Ternary Walsh Transform and Its Operations for Completely and Incompletely Specified Boolean Functions[Show abstract] [Hide abstract]
ABSTRACT: The new ternary Walsh transform is considered in this paper. Such a ternary Walsh transform can be used in a similar manner as the standard Walsh transform for binary logic functions as shown here. It is based on the Kronecker product as well as the Galois field and new ternary operations. The same hardware implementation can be used for both forward and inverse ternary Walsh transforms based on its fast algorithms and properties. The ternary Walsh transform is suitable for processing both completely and incompletely specified Boolean functions. Its properties for the decomposition and symmetry detections of the Boolean functions are shown.Circuits and Systems I: Regular Papers, IEEE Transactions on 09/2007; 54(8-54):1750 - 1764.

Conference Paper: Logic Synthesis Importance in FPGA-Based Designing of Image and Signal Processing Systems[Show abstract] [Hide abstract]
ABSTRACT: General functional decomposition has been gaining more and more importance in recent years. Though it is mainly perceived as a method of logic synthesis for implementation of Boolean functions into FPGA-based architectures, it has found application in many other fields of modern engineering and science. In this paper, application of logic decomposition to efficient implementation of image and signal processing system in modern FPGA architectures is described. We have adapted an algorithm called Demain that can be used as a preprocessing tool in the FPGA synthesis flow. Wavelet filters are used to test Demain with Altera's Stratix device family and the experimental results are compared with those by Altera's Quartus tool. When Demain is used as a premapping processing, it shows 50% improvement in terms of the covered area by embedded memory blocks.Mixed Design of Integrated Circuits and Systems, 2007.
