“…The device presented in this paper is based on the latest technology of reconfigurable software systems and has as its main function the metering of electricity and as an auxiliary function the analysis of the quality of electricity at the point of interface between the electricity supplier and the electricity consumer. The device is based on an embedded system built around the MicroBlaze microprocessor configurable by software provided by Xilinx for the latest generation programmable logic arrays (FPGAs) [2][3][4].…”

Many areas of activity face the problem of electricity quality. At the same time, diagnosing the quality of the energy provided makes it possible to identify and remedy problems that have arisen in the system. Advanced signal processing techniques and the use of advanced systems allow for a complex analysis of the phenomenon. The paper presents an electricity meter equipped with an electricity quality analysis system. It was developed based on the Xilinx Artix-7 programmable logic matrix. A Digilent Arty A7 development board was used due to its design and experimentation facilities. The developed system determines the power consumed and the main elements that define the quality of electricity: harmonics and other deviations from the frequency of nominal power supply, flicker, voltage gaps, voltage variations, transient surge, temporary surge, etc. The possibility of using an embedded system equipped with the Microblaze soft microprocessor, the existence of a 12-bit analog-digital converter and the maximum sampling frequency of 1 MSPS and the possibility of assisted design allows to obtain a measurement system with superior characteristics. The results obtained and the experiments carried out confirm the expected performance for the electricity meter.

“…This fact is due to the high volume of data and the amount of operations intrinsic to this kind of applications, such as real-time image processing, financial, or bioinformatics solutions. In front of the general purpose processors (GPPs), the industry has moved toward developing systems relying on high performance computing platforms [3] [4] as an alternative. Multiprocessor systems and hardware accelerators are clear examples of this fact.…”

A hierarchical scheduling and management solution for dynamic reconfiguration in FPGA-based embedded systems

One of the limiting factors that have prevented a widely dissemination of the reconfigurable technology is the absence of an appropriate model for certain target applications capable of offering a reliable control. Moreover, the lack of flexible and easy-to-use scheduling and management systems are also relevant drawbacks to be considered. Under static scenarios, it is relatively easy to schedule and manage the reconfiguration process since all the variations corresponding to predetermined and well-known tasks. However, the difficulty increases when the adaptation needs of the overall system change semi-randomly according to the environmental fluctuations. In this context, this work proposes a change in the paradigm of dynamically reconfigurable systems, by attending to the dynamically reconfigurable control problematic as a whole, in which the scheduling and the placement issues are packed together as a hierarchical management structure, interacting together as one entity from the system point of view, but performing their tasks with certain degree of independence each other. In this sense, the top hierarchical level corresponds with a dynamic scheduler in charge of planning and adjusting all the reconfigurable modules according to the variations of the external stimulus. The lower level interacts with the physical layer of the device by means of instantiating, relocating, removing a reconfigurable module following the scheduler's instructions.In regards to how fast is the proposed solution, the total partial reconfiguration time achieved with this proposal has been measured and compared with other two approaches: 1) using traditional Xilinx's tools; 2) using an optimized version of the Xilinx's drivers. The collected numbers demonstrate that our solution reaches a gain up to 10 times faster than the other approaches.

“…On the other hand, hardware implementation is suitable for fast responding systems because, they can do massive calculations in very short time. In this context, reconfigurable computers offer a compromise between the performance advantages of fixed-functionality hardware and the flexibility of programmable substrates (Azarian and Ahmadi, 2009;Kuon et al, 2008;Singh et al, 2001). Presently, field programmable gate arrays (FPGA) is the core processing element of most reconfigurable computers.…”

For many years digital controllers have been implemented using microprocessors, microcontrollers, digital signal processors etc. Recently, field programmable gate arrays (FPGA) is found to be an alternative because of its high processing speed. In this context, this paper presents the implementation of state space controller (SSC) on FPGA. SSC contains an observer to estimate the system unknown states variables. Matrix multiplications involved in this estimation take most of the computation time of the controller. In order to make SSC much more competent for controlling fast dynamic systems, a new FPGA based parallel architecture is proposed. The reduction in computation time with optimal hardware resources is achieved by developing an efficient multistage matrix multiplication algorithm (MMM). The performance of FPGA-based SSC is validated by implementing it in an inverted pendulum control system. The design is mapped on xilinx virtex-5 FPGA device with a maximum frequency of 449.438MHz.
