Fuzzy Logic Controller (FLC) systems have emerged as one of the most promising areas for Industrial Applications. The highly growth of fuzzy logic applications led to the need of finding efficient way to hardware implementation. Field Programmable Gate Array (FPGA) is the most important tool for hardware implementation due to low consumption of energy, high speed of operation and large capacity...

Modular exponentiation is the cornerstone computation in public key cryptography systems such as RSA cryptosystems .The operation is time consuming for large operands. This paper describes the characteristics of three architectures designed to implement modular exponentiation using the fast binary method: the first field programmable gate array (FPGA) prototype has a sequential architecture, th...

In this work, we demonstrate the use of a Field Programmable Gate Array (FPGA) as a physical platform for realizing chaotic delay differential equations (DDE). Moreover, using our platform, we also experimentally study the synchronization between two time delayed systems. We illustrate two different experimental approaches – one is hardware co-simulation (using a Digilent Atlys with a Xilinx Sp...

In this paper, the Polynomial Matrix Multiplication (PMM) of polynomial vectors and/or polynomial matrices have been introduced. This method provides an improvement of the fast convolution technique to multiple inputs multiple output systems (MIMO). It is devoted to the hardware implementation of PMM. The hardware implementation of this method is achieved via partly systolic, field programmable...

—After the appearance of Field Programmable Gate Array (FPGA), several systems have been built using FPGAs,thus called Reconfigurable System. The essence of Reconfigurable System is dynamically changing the circuit at runtime with the reconfigurable characteristic of Programmable Logic Devices to give the system advantages of both hardware and software. The thesis here starting from the basic t...

This paper presents a Xilinx Field Programmable Gate Array (FPGA) based speed control of AC Servomotor using sinusoidal PWM technique. Xilinx FPGA is a programmable logic device developed by Xilinx which is considered as an efficient hardware for rapid prototyping. It is used to generate 50 Hz sine wave, the triangular wave and the sinusoidal PWM signals. The sinusoidal pulse width controls the...

This paper presents a new design for testing SRAM-based field programmable gate arrays (FPGAs). The original FPGA’s SRAM memory is modified so that the FPGA may have the facility to loop the testing configuration data inside the chip. The full testing of the FPGA is achieved by loading typically only one carefully chosen testing configuration data instead of the whole configurations data. The o...

Following the simple Programmable Logic Device (SPLD) and Field Programmable Gate Array (FPGA) generations a third generation of programmable logic technologies is now reaching the marketplace. These new architectures are driven by the move to system level integration and fast expanding markets such as networking and wireless communications which are not addressed adequately by mainstream FPGA'...
