A framework for remote and adaptive partial reconfiguration of SoC based data acquisition systems under Linux

Data acquisition forms the most integral part of industrial systems. Control and monitoring of parameters in hazardous areas have to be performed remotely. In this paper a framework for dynamically reconfiguring data acquisition system has been proposed. The main features of this framework are its ability to be controlled, partially reconfigured and monitored remotely. The proposed framework is capable of detecting the identity of the sensor connected to a partial reconfigurable region. The system uses embedded Linux to implement the configuration, control logic and the device drivers to communicate with the partial reconfigurable region. The proposed framework is tested with an accelerometer ADXL362 as a sensor connected to XC7Z020 SoC from the Xilinx Zynq-7000 family. The system is able to detect the presence and absence of the accelerometer. Partial reconfiguration time of 10 ms and the full reconfiguration time of 310 ms is achieved.
