DBPM system performance is determined by the design and implementation of beam position signal processing *** order to develop the system,a beam position signal processing algorithm is implemented on *** hardware is a PMC board ICS-1554A-002(GE Corp.)with FPGA chip *** paper adopts quadrature frequency mixing to down convert high frequency signal to *** from conventional method,the mixing is implemented by CORDIC *** algorithm theory and implementation details are discussed in this *** the board contains no front end gain controller,this paper introduces a published patent-pending technique that has been adopted to realize the function in digital *** whole design is implemented with VHDL language. An on-line evaluation has been carried on SSRF(Shanghai Synchrotron Radiation Facility)storage *** indicate that the system turn-by-turn data can measure the real beam movement accurately,and system resolution is 1.1μm.
