This paper designed an embedded sensor data communication system based on FPGA.Using FPGA chip and NiosⅡ processor,the four SSI interface magnetostrictive sensor signals were measured and the communications between PMC bus and FPGA were attained.The hardware of system was composed of magnetostrictive sensor,FPGA core chip,PCI9030,PMC bus,and the software of system which programmed with hard description language was composed of the data receiving,the code transform,the data link,the local interface and the NiosⅡ embedded processor.The scheme made full use of embedding technique,implementing the measurement and the communication of the displacement sensor data with less hardware.The whole debugging of the system was presented.The experimental result indicates that this scheme is efficient,reliable,and can meet the requirements of measurement and communication.
