Software development for uTCA-based LLRF control system

Modern experiments in particle physics are based on advanced and sophisticated electronic systems. LLRF control system requires simultaneous data acquisition of multiple ADC channels and real time signal processing between pulses. Due to very high requirements related to reliability, availability, accessibility and efficiency development of software for such systems is very complex process. Additionally, designed applications have to be prepared for continuous changes of functionality because development of entire system is still in progress. The paper presents the architecture of software for LLRF control system developed for the XFEL accelerator, starting from device drivers for uTCA-based hardware components of system available through PCIe bus and finishing on specialized version of DOOCS server.
