Modernization of the L-1 trigger of the CMD-3 detector

This paper describes the trigger system of the CMD-3 detector at the VEPP-2000 electron-positron collider and presents the results of its modernization. We review the operating principles and architecture of the original system. A key upgrade involved the development of a new Decision Making Block, which implements improved algorithms for selecting events of interest. This modernization enhanced the system's performance while maintaining high event registration efficiency. Tests under real experimental conditions confirmed the stable operation of the upgraded trigger system.
