Description
An upgrade of the Shanghai Free Electron Laser (SXFEL) BPM signal processor is under preparation to implement the high-speed intelligent commissioning and bunch-by-bunch feedback control of the SXFEL beam. The function of synchronizing the acquisition of all BPM data from the SXFEL will be implemented. A new digital carrier board has been developed, using a Zynq UltraScale+ MPSoC FPGA as the core, an FMC slot for White Rabbit timing module to accept bunch ID and trigger, and 10Gb SFP ports for high-speed data transmission between the processors. The design of the hardware, firmware and software of the upgraded BPM signal processor will be introduced in this paper.
