数字BPM信号处理器的研制进展

Progress of Digital BPM Signal Processor

介绍了上海光源束测组自行研制的基于FPGA和ARM的一体化数字BPM信号处理器的进展,包括系统结构、关键技术创新、性能评估和下一步研究计划。该处理器是国内首台研制成功的BPM信号处理器,在研制过程中取得多项关键技术的突破,逐圈位置分辨率达到亚微米,与国际同类产品处于相同水平。目前,该处理器已完成第2版样机的研制,正进行进一步系统优化。

A digital BPM signal processor prototype has been developed in Shanghai Synchrotron Radiation Facility （SSRF）, which is based on FPGA and ARM. In this paper, the processor progress was introduced, including the processor structure, key innovation, performance evaluation and future plan. It is the first BPM signal processor developed in China. Some essential technical breakthroughs were made during the devel- opment, and it can reach sub-micrometer position resolution, which is the same level of international product. The second version processor prototype was developed, and further system optimization is in progress.
