Several techniques are available for implementing DC-DC converters using digital controllers Among these FPGA (Field Programmable Gate Array) based implementation provides various advantages in terms of speed, flexibility, low power usage, reduced equipment sizing and massive parallelism. The traditional methods allow fault diagnosis only after the final implementation which leads to extra cost...

Placement process is one of the vital stages in physical design. In this stage, modules and elements of circuit are placed in distinct locations according to optimization basis. So that, each placement process tries to influence on one or more optimization factor. In the other hand, it can be told unequivocally that FPGA is one of the most important and applicable devices in our electronic worl...

Aiming at providing a better user experience, we propose a gestural remote control able to operate infrared-enabled devices with simple hand movements. In the proposed system, the user’s hands are identified by red and green gloves. The X and Y coordinates of each hand’s center of mass are calculated and input into a gesture recognition finite state machine (FSM). This FSM classifies the hand m...

In this paper, the design and implementation of a real-time traffic light control system based on Fieldprogrammable Gate Array (FPGA) technology is reported. The traffic light control system is designed with VHDL language. Its function was verified with simulation. After that, the VHDL design was downloaded to FPGA board hardware to verify its function in experiment. The designed traffic light ...

Although a Programmable Logic Controller (PLC) has been widely adopted for the sequence control of industrial machinery, its performance does not always satisfy the recent requirements in large and highly responsive systems. With the state-of-the-art FPGA technology, it is possible to implement a control program with hard-wired logic for higher response and reduced implementation cost/space. Th...

This paper presents a novel eld-programmable gate array logic block architecture which incorporates support for digit-serial DSP architectures on a digit wide basis, without diminishing the support for random and control logic applications. To eeciently realize a digit-serial DSP design on FPGAs, one must create an FPGA architecture optimized for those types of systems. Key to the suitability o...

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...

Recent trends in Radio Telescopes deploy BLDC motors for their 2-axis rotation. BLDC motors implement electronic commutation by avoiding carbon brushes and mechanical commutation. Resolvers mounted on rotor shaft of BLDC motors form good sensor feedback and work in-conjunction with RDC and FPGA interface to implement speed and position control. Brushes in DC torque form an important source of a...

The ITER Interlock Control System (ICS) requires the application of IEC 61508 standard for all mission-critical (known as investment protection) control functions. Such functions must detect events integrated physical processes and distribute them to actuators with hard real-time constraints on order milliseconds or even microseconds. Systems able achieve these timing requirements are often bes...
