A computer-implemented thread is provided for communicating with other threads in a set-top box environment. The thread includes a stack, a thread control block, and a queue object. The thread's stack provides data storage for the thread, and the thread control block is utilized for storing context information related to the thread. The queue object is utilized for providing communications between the thread and another thread. A swap type detector can be provided for detecting a predetermined swap type for when the thread is swapped from the CPU. A register recorder partially stores the CPU state of the thread based upon the detected swap type of the thread. The register recorder also can perform a partial storage of the CPU state of the thread based upon a received interrupt service request.
