Multithreading provides an adequate support for concurrent programming, but requires the software developer to take care of the correct synchronization and exchange of data among threads. In this paper we propose an architecture-driven approach to the thread synchronization management, which is completely transparent to the software developer. This is realized by implementing a suitable Java package -- which adheres to a general synchronization model and is inspired by the main architectural abstractions -- by means of which well-synchronized multithreaded Java programs can be synthesized from their architectural specifications. The approach is illustrated by means of a real-time audio processing system.
