“…The communications interfaces implemented for or with FPGAs have developed at the same rate that these interfaces have grown for other technologies, like computer or mobile interfaces. The implementations of these communication interfaces in FPGAs aims to high speed/real-time data capturing systems [565,[1524][1525][1526][1527][1528][1529][1530][1531], security network processors [144,145], image capturing [108,113,[1532][1533][1534] [407,[1574][1575][1576], reconfigurable cryptographic processors [1577][1578][1579] and low power consumption implementations [470,472,1580,1581].…”

Field Programmable Gate Array (FPGA) is a general purpose programmable logic device that can be configured by a customer after manufacturing to perform from a simple logic gate operations to complex systems on chip or even artificial intelligence systems. Scientific publications related to FPGA started in 1992 and, up to now, we found more than 70,000 documents in the two leading scientific databases (Scopus and Clarivative Web of Science). These publications show the vast range of applications based on FPGAs, from the new mechanism that enables the magnetic suspension system for the kilogram redefinition, to the Mars rovers’ navigation systems. This paper reviews the top FPGAs’ applications by a scientometric analysis in ScientoPy, covering publications related to FPGAs from 1992 to 2018. Here we found the top 150 applications that we divided into the following categories: digital control, communication interfaces, networking, computer security, cryptography techniques, machine learning, digital signal processing, image and video processing, big data, computer algorithms and other applications. Also, we present an evolution and trend analysis of the related applications.

“…The ISTTOK data acquisition has been migrated from VME to PCI modules (PCI-TR-256), developed at CFN [8]. The main characteristics of this module are: (i) 8 galvanic isolated channels, with 14-bit ADC @ 2 MHz; (ii) a Texas Instruments Fixed-Point DSP @ 500 MHz (TMS320C6415); (iii) a Xillinx FPGA (Spartan-IIE XC2S400E); and (iv) 512 MB SDRAM memory module.…”

This paper reviews the recent work developed on ISTTOK. A wide variety of diagnostic tools, instrumentation and systems have been developed demonstrating that small tokamaks can play an important role in the fusion community. Furthermore, a physics programme has been carried out with particular emphasis on the control and characterization of the edge fluctuations. Recently, the ISTTOK programme has also dedicated particular attention to the development of plasma facing components being both liquid metal limiters and nanostructured materials.

“…The plasma position controller system is implemented in the digital processing module and it determines the necessary response from the actuators. The data acquisition and processing board used for this module is the transient recorder PCI-TR-512 [3] intelligent card based on PCI (Peripheral Component Interconnect) technology with 8 galvanically isolated analog channels, a DSP (Digital Signal Processor) for data processing and feedback control on the plasma R and Z directions, an FPGA (Field Programmable Gate Array) to control data acquisition and a multichannel buffered serial port for communication with both power supplies.…”

Active control of plasma position on the ISTTOK tokamak is of extreme importance due to the inherent instability caused by an unfavourable curvature of the external equilibrium magnetic field. The consequences of this instability can be suppressed by applying a dynamic equilibrium field. A digital real-time plasma position control system for ISTTOK has been developed to perform this task. This system uses magnetic measurements to determine the plasma position and feeds the control signal to power supplies that generate the equilibrium fields. After commissioning, the results obtained have shown some discrepancies between the magnetic plasma position reconstruction and several other diagnostics, such as tomography. This discrepancy at some extent is due to the effect of the external magnetic fields on the poloidal magnetic measurements. This work presents a study that addresses this issue. In a future work it will lead to the development of a corrected plasma position algorithm, aiming at obtaining improved performance of plasma discharges and controlled plasma column displacements.
