Following the simple observation that the interconnection of a set of quantum optical input-output devices can be specified using structural mode VHSIC hardware description language, we demonstrate a computer-aided schematic capture workflow for modelling and simulating multi-component photonic circuits. We describe an algorithm for parsing circuit descriptions to derive quantum equations of mo...

This paper describes the principles of high level modeling of digital hardware circuits using the Extended Timing Diagrams (ETD) formalism which adds conditions, events, action expressions and particular constraints to traditional timing diagrams. Hierarchy and concurrency are integrated too such that a full top-down design becomes possible, enhancing in the same time the readability. While for...

In this paper we propose a technique for software-implementation of an lifting with the goal of getting a customizable lifting DWT-core which can be used as a module in implementing a bigger system irrespective of ones choice of implementation platform. Here we have written the core processor Microblaze is designed in VHDL (VHSIC hardware description language), implemented using XILINX ISE 8.1 ...

Today, real-time processing has become a stipulation in all practical fields especially in image processing. This paper presents an experimental comparison of implementation of Niblack’s Algorithm, a binarization algorithm for image-processing in Visual C++ using OpenCV library with its implementation on FPGA. It aims at addressing the real-time processing scenario and how to overcome the situa...

In this paper, an efficient design scheme for implementation of the Proportional-IntegralDerivative (PID) controller using Field Programmable Gate Array (FPGA) technology is presented. It is efficient scheme in the sense dynamic power system, effective cost over other digital implementation techniques and etc. The VHDL (VHSIC Hardware Description Language; VHSIC: very-high-speed-integrated circ...

41  Abstract—Digital design is an amazing and very broad field. The applications of digital design are present in our daily life, including computers, calculators, video cameras etc. The VHDL (VHSIC Hardware Description Language) has become an essential tool for designers in the world of digital design. This paper presents implementation of a 32-bit Arithmetic Logic Unit (ALU) using VHDL. Here...

This paper presents a methodology to integrate a fuzzy coprocessor described in VHDL (VHSIC Hardware Description Language) to a soft processor embedded into an FPGA, which increases the throughput of the whole system, since the controller uses parallelism at the circuitry level for high-speed-demanding applications, the rest of the application can be written in C/C++. We used the ARM 32-bit sof...

A novel cryptographic algorithm mainly depends on the cellular automata .In order to get the randomness using cellular automata concept. In this algorithm we have mainly concentrated on cellular automata module we have 8 different rules for different rounds .In previous algorithm the message and key size was 128bit, but in this project to eliminate all the unnecessary logic operations present i...

This paper presents the simulation results of digital modulation schemes BPSK and QPSK. Digital modulation is less complex, more secure and more efficient in long distance transmission. The noise detection and correction in digital is more efficient than analog. So it has more importance in modern communication system. These digital modulation schemes can be realized using FPGA ( Field Programm...

VHSIC Hardware Description Language (VHDL) simulation of trapezoidal filtering algorithm was done. The exponentially decaying sequences were considered as the input to the filter. Such kinds of signals are usually obtained after processing (i.e. in analog domain) and digitizing the nuclear detector signals. The trapezoidal filter acts as a pulse shaping filter in a typical nuclear spectroscopy ...
