本报告概述了VME PMC载板（VPC）的设计概念和应用，VME 64x板是在PSI开发的，作为PSI电子和质子加速器束流仪表的通用数字后端。VPC的两个Xilinx Virtex2Pro FPGA允许在单芯片（“SOC”）上实现束流仪表系统的完整数字部分，包括探测器前端接口、滤波器、互锁、反馈链路、FFT等高级数据分析以及通用控制系统接口。除了FPGA的两个片上PowerPC处理器外，VPC还提供DSP、RAM和多千兆光纤链路，用于分布式反馈和同步。VPC的首次应用包括PSI质子加速器的数字质子束位置监测器（DBPM）和束轮廓监测器，μ子衰变实验的几千个探测器通道波形的读出，以及将光子BPM集成到SLS快速轨道反馈（FOFB）中。除了这些应用程序的状态报告和初步结果外，还将对VPC未来可能的应用程序进行展望。
This report gives an overview of the design concept and applications of the VME PMC Carrier board (VPC), a VME64x board that was developed at PSI as a common digital back-end for beam instrumentation at the PSI electron and proton accelerators. The two Xilinx Virtex2Pro FPGAs of the VPC allow the implementation of the complete digital section of a beam instrumentation system on a single chip ("SOC"), including detector frontend interface, filters, interlocks, feedback links, high-level data analysis like FFTs, and a generic control system interface. In addition to the two on-chip PowerPC processors of the FPGAs, the VPC provides a DSP, RAM, and multi-gigabit fibre optic links for distributed feedbacks and synchronisation. First applications of the VPC include digital proton beam position monitors (DBPMs) and beam profile monitors for the PSI proton accelerators, the readout of several thousand detector channel waveforms for a muon decay experiment, and the integration of photon BPMs into the SLS fast orbit feedback (FOFB). In addition to a status report and first results for these applications, an outlook on possible future applications of the VPC will be given.
