High level design of adaptive distributed controller for partial dynamic reconfiguration in FPGA

Abstract

Controlling dynamic and partial reconfigurations becomes one of the most important key issues in modern embedded systems design. In fact, in such systems, the reconfiguration controller can significantly affect the system performances. Indeed, the controller has to handle efficiently three major tasks during runtime: observation (monitoring), taking reconfiguration decisions and notify decisions to the rest of the system in order to realize it. We present in this paper a novel high level approach permitting to model, using MARTE UML profile, modular and flexible distributed controllers for dynamic reconfiguration management. This approach permits components/ models reuse and allows systematic code generation. It consequently makes reconfigurable systems design less tedious and reduces time to market.

Field Programmable Gate Array Applications—A Scientometric Review

“…In this review we divided these applications into eleven categories and in each category we presented the applications with most documents related to them, totaling 150 applications described in this review. For digital control we found that the most important control techniques are implemented in FPGAs, like fuzzy control [1499][1500][1501][1502], PID [69,1503,1504], model predictive control [73,76,1505], adaptive control [80,81,1506], sensorless control [1507][1508][1509] and distributed control [96,99,101]. These digital control techniques were implemented in FPGAs due the high speed response that a hardware digital control FPGA-based implementation can achieve and its reconfiguration capability, allowing control application to high speed system such as induction motors [1507,[1510][1511][1512], torque control [75,1513,1514], Brushless DC (Direct Current) motors [1515][1516][1517], current control [1518,1519], among others [65,[1520][1521][1522][1523].…”

“…Each cell has autonomy in local optimization and also all integrate a large complex system [95]. FPGA-based distributed control techniques have been used for applications like micro-electromechanical systems arrays for air-flow planar micro-manipulation [96], music playing robots [97][98][99], telescopes control [100] and for reconfigurable FPGA-based systems [101][102][103].…”

High Level Design of Adaptive Real-time Embedded Systems - A Survey

“…They have also defined other extensions to support some Xilinx specific concepts such as bus macro, which permits routing between static and reconfigurable regions, the Internal Reconfiguration Access Port (ICAP), which assures the configuration memory read/write at run-time and the Reconfigurable Hardware Accelerator (RHA). Some control mechanisms have been added in (Cherif et al, 2011). A distributed modular reconfiguration controller has been presented.…”
