MULTIPLEKSER BERBASIS PROGRAMMABLE LOGIC DEVICE (PLD)

Programmable real-time FIR-filter logic device

This paper resumes the development of an integrate tool for designing high-speed, real-time, FIR-filter circuits. The system is composed of programmable IC and an associate software for filter response analysis, synthesis of coefficients, and circuit programming. The architecture is highly regular, easily expandable and its control is distributed. The chip can be programmed by a PC or by using ...

Quaternary Arithmetic Logic Unit on a Programmable Logic Device

Common binary arithmetic operations such as addition/subtraction and multiplication suffer from O(n) carry propagation delay where n is the number of digits. Carry lookahead helps to improve the propagation delay to O(log n), but is bounded to a small number of digits due to the complexity of the circuit. A carry-free arithmetic operation can be achieved using a higher radix number system such ...

Logical Function Decomposition Method for Synthesis of Digital Logical System Implemented with Programmable Logic Devices (PLD)

The paper consists in the use of some logical functions decomposition algorithms with application in the implementation of classical circuits like SSI, MSI and PLD. The decomposition methods use the Boolean matrix calculation. It is calculated the implementation costs emphasizing the most economical solutions. One important aspect of serial decomposition is the task of selecting “best candidate...

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers

This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
