Development of γ dose rate monitor based on FPGA and single-chip microcomputer

A novelγdose rate monitor with multiple channels signal collection in which takes the FPGA as the core process chip and single-chip microcomputer as the data processor had been developed. This paper introduced the communication interface design between FPGA and MCU, and gave the data acquisition module and the function simulation chart designed by FPGA. In addition, the software and hardware design diagrams of MCU had been given in this paper. The maximum digitallization was carried on in the designing process. The experiments showed that the scheme for the system matched to the requests completely. (authors)
