Reduction in the number of LUT elements for control units with code sharing

Alexander Barkalov, Larysa Titarenko, Jacek Bieganowski (2010)

International Journal of Applied Mathematics and Computer Science

Similarity:

Two methods are proposed targeted at reduction in the number of look-up table elements in logic circuits of compositional microprogram control units (CMCUs) with code sharing. The methods assume the application of field-programmable gate arrays for the implementation of the combinational part of the CMCU, whereas embedded-memory blocks are used for implementation of its control memory. Both methods are based on the existence of classes of pseudoequivalent operational linear chains in...

Reduction in the number of PAL macrocells in the circuit of a Moore FSM

Alexander Barkalov, Larysa Titarenko, Sławomir Chmielewski (2007)

International Journal of Applied Mathematics and Computer Science

Similarity:

Optimization methods of logic circuits for Moore finite-state machines are proposed. These methods are based on the existence of pseudoequivalent states of a Moore finite-state machine, a wide fan-in of PAL macrocells and free resources of embedded memory blocks. The methods are oriented to hypothetical VLSI microcircuits based on the CPLD technology and containing PAL macrocells and embedded memory blocks. The conditions of effective application of each proposed method are shown. An...

Creation of unequal error protection codes for two groups of symbols

Eugeniusz Kuriata (2008)

International Journal of Applied Mathematics and Computer Science

Similarity:

This article presents problems of unequal information importance. The paper discusses constructive methods of code generation, and a constructive method of generating asymptotic UEP codes is built. An analog model of Hamming's upper bound and Hilbert's lower bound for asymptotic UEP codes is determined.

Application of triple correlation and bispectrum for interference immunity improvement in telecommunications systems

Pavel Molchanov, Alexandr Totsky (2008)

International Journal of Applied Mathematics and Computer Science

Similarity:

This paper presents a new noise immunity encoding/decoding technique by using the features of triple correlation and bispectrum widely employed in digital signal processing systems operating in noise environments. The triple correlationand bispectrum-based encoding/decoding algorithm is tested for a digital radio telecommunications binary frequency shift keying system. The errorless decoding probability was analyzed by means of computer simulation for the transmission and reception of...

On some Optimal (n,t,1,2) and (n,t,1,3) Super Imposed Codes

Manev, Mladen (2009)

Serdica Journal of Computing

Similarity:

Partially supported by the Technical University of Gabrovo under Grant C-801/2008 One of the main problems in the theory of superimposed codes is to find the minimum length N for which an (N, T,w, r) superimposed code exists for given values of T , w and r. Let N(T,w, r) be the minimum length N for which an (N, T,w, r) superimposed code exists. The (N, T,w, r) superimposed code is called optimal when N = N(T,w, r). The values of N(T, 1, 2) are known for T ≤ 12 and the values...
