This lecture introduces reconfigurable computing and the field-programmable gate array (FPGA) by discussing the density advantage of configurable computing and some of the trade offs involved in designing and FPGA. Some important conclusions were that wiring and routing area dominate total area, three and four input lookup tables are ideal for area efficiency, five and six input lookup tables a...

New testing methods are required as the complexity of Field Programmable Gate Array (FPGA) designs grow rapidly and time-to-market demands shorten. In this paper we propose a new, physical fault injection method for the test of a system’s self-stabilizing property, that is its intrinsic ability to recover from transient faults. Therefore we inject transient faults in Look-Up Table (LUT)-based F...

A field programmable gate array (FPGA) -based implementation of a physical random number generator (PRNG) is presented. The PRNG uses an alternating step generator construction to decorrelate an oscillator-phase-noise-based physical random source. The resulting design can be implemented completely in digital technology, requires no external components, is very small in area, achieves very high ...

This paper presents the use of field-programmable gate array (FPGA) in a miniature Ion Mobility Spectrometer (IMS) sensor system. This IMS sensor is for detection of subsurface gaseous volatile organic compounds (VOCs). This paper describes how an FPGA is used to process the data collected from the sensor and control its overall operation. A Xilinx Microblaze soft-core processor is used to ease...

Current digital, directly mapped implementations of spiking neural networks use serial processing and parallel arithmetic. On a standard CPU, this might be the good choice, but when using a Field Programmable Gate Array (FPGA), other implementation architectures are possible. This work present a hardware implementation of a broad class of integrate and fire spiking neurons with synapse models u...

An implementation of a reconfigurable FPGA (Field-Programmable Gate Array) is proposed for digital control and acquisition tasks associated with a water quality sensor calibration system. The system permits the water quality (WQ) sensor auto-calibration based on FPGA control of different actuators (pumps and electrovalves) and of WQ data sensor acquisition, real time WQ data processing based on...

A power efficient Fast Fourier Transform (FFT) processor for use in the Direction of Arrival (DOA) estimation of a wideband waveform is presented. The target device for implementation is a Xilinx Spartan-3 Xc3s200 Field Programmable Gate Array (FPGA). The FFT processor was developed using the Xilinx ISE in Verilog code. Although the parallel and pipelined architecture uses a large portion of th...

In this report we describe an adaptation of the Hough transform for the tracking of particles in the CBM STS detector, together with a possible implementation of the algorithm in hardware using FPGA (field programmable gate array) as a level-1 trigger. A first FPGA based R&D hardware prototype that can be used also for a variety of other application (e.g. Data Combiner and Active Buffer) is als...

A portable laser photoacoustic sensor for methane (CH₄) detection based on a field-programmable gate array (FPGA) is reported. A tunable distributed feedback (DFB) diode laser in the 1654 nm wavelength range is used as an excitation source. The photoacoustic signal processing was implemented by a FPGA device. A small resonant photoacoustic cell is designed. The minimum detection limit (1σ) of 1...

We developed a highly integrated, Field Programmable Gate Array (FPGA)-based digital multi-frequency eddy current platform which is capable of detecting surface breaking and subsurface cracks in non-magnetic plates. Excitation signal generation, receiving signal demodulation, and USB communication were all implemented inside a Xilinx FPGA (Spartan III). Multi-frequency test results provide rich...
