Abstract: The embedded data acquisition system for the Experimental Advanced Superconducting Tokamak (EAST) was designed. This system is based on the FPGA and ARM technology, integrates signal conditioning, data acquisition and processing into the single board, and provides a high integration and portability level architecture. At the same time, the “time sliced” technology is introduced into the software system for providing a continuous acquisition and quasi real-time data transferring capability.
