Maintaining and improvement of central rotated rock-seizing machine in well construction;

Meanwhile,in order to improve the slow speed in dynamic configuration for the Xilinx Virtex series,the capture and writeback circuits are also included in the proposed circuit,which helps to realize the status saving and resuming of the circuits during dynamic reconfiguration and to accelerate the reconfiguration speed for FPGA.
