The linear accelerators; like Free-electron LAser in Hamburg (FLASH) or the European X-Ray Free Electron Laser (E-XFEL) take advantage of digital Low Level Radio Frequency (LLRF) system to control the phase and amplitude of electromagnetic field inside superconducting cavities. The real-time control LLRF system; processing data within a few micro seconds; must fulfil the performance requirements and provide monitoring and diagnostics. The AMC-based Controller (DAMC-TCK7) board was developed as a general purpose high-performance low-latency data processing unit designed according to the PICMG MTCA.4 spec. The module provides processing power; data memory; communication links; reference clock; trigger and interlock signals that are required in modern LLRF control systems. The module was originally designed as a Low Level Radio Frequency cavity field stabilizing controller for standing-wave linear accelerators. However; the application of the board is much wider; it is general purpose data processing module suitable for systems requiring low latency and high speed digital signal processing. This paper discusses the requirements for the digital real-time data processing module and presents the laboratory performance evaluation. © 2014 IEEE;
