PSI is using the Xilinx/AMD Zynq UltraScale⁺ (ZynqU⁺) MultiProcessing System-on-Chip (MPSoC) on different hardware platforms, ranging from VME and CompactPCI-Serial (CPCI-S) cards to customized platforms for high-volume applications like beam position monitors (BPMs) and magnet power supplies (PS).
The first ZynqU⁺ application at PSI was "DBPM3", a generic hardware platform for BPMs presently used for
cavity BPMs in SwissFEL as well as button and stripline BPMs for the SLS 2.0 project. The DBPM3 platform has a digital backend with a ZynqU⁺, combined with an application-specific analog RF Front-End (RFFE) with integrated fast JESD204B ADCs.
This paper describes our experience with the application of ZynqU⁺ for EPICS IOCs of different applications at
PSI, with focus on our first BPM applications. However, many of the topics and solutions discussed are also relevant and applicable for other applications.
