Design of Number Controlled Oscillator in Accelerator Digital Beam Position Monitor

有鉴于高品质NCO是数字BPM系统重要设计内容之一,利用CORDIC完成了NCO的设计与实现,内容包括NCO参数的设计,系统框架设计、控制流程设计、结果检验和资源占用情况分析等。结果检验是在XC5VSX95T硬件平台上利用Chip Scope工具来完成的。结果表明,该方法能够有效设计出满足数字BPM系统需求的NCO,并在束流位置测量系统建设中发挥积极作用。

Considering the fact that the high quality number controlled oscillator is one of important part in digital Beam Position Monitor, the design and implementation of NCO is completed by the CORDIC algorithm in this thesis, including the design of parameters, the design of system framework, the design of controlling, the test of results and the analysis of resource consumption. The results are verified by the tool of ChipScope on the hardware platform of XC5VSX95T. The results show that this method can effectively design the NCO which can meet the requirements in digital Beam Position Monitor, and play an important role in the construction of the Beam Position Monitor.
