Abstract
The CMD-3 detector is in operation at the VEPP-2000 \({{e}^{ + }}\) \({{e}^{ - }}\) collider at Budker Institute of Nuclear Physics since 2008. The upgrade of the triggering subsystem is in progress: the new algorithm for the online processing is proposed, and the prototype of the Trigger Decision Board has been developed. The new algorithm enables more accurate measurements of the energy and the cluster coordinates in the calorimeters. The special work station has been constructed to verify Trigger Decision Board performance. Some results and description of the main technical solutions are presented.
