Abstract: Large ICF experiments require their physical diagnosis systems to be equipped with a sophisticated central control system, which makes sure the whole experiment would be safe and efficient. An integrated central control system framework for physical diagnosis system serving for domestic ICF large laser device, which is being built, is brought forward. Two subsystems in the central control system are designed with field programmable gate array(FPGA) technology, implementing a high performance embedded system on chip(SoC) platform for instruction synchronous system in FPGA and integrating the synchronous trigger system into a PXI system for central control by FPGA.
