Abstract: A diagnostic tool for a portable thread environment is disclosed. In one embodiment, a system comprises a first portable thread environment (PTE), comprising a diagnostic tool; a second PTE configured to receive and send threads; a third PTE configured to receive and send the threads; and a PTE router configured to receive the threads and route said threads, wherein the router copies the threads and routes the copies to the diagnostic tool.

Abstract: A portable thread environment comprising: an application programming interface configured to support multiple application program tasks, wherein each task is either a preemptive task comprised of preemptive threads or a cooperative task comprised of cooperative threads; host adaptation logic for communicatively interfacing said cooperative tasks, preemptive tasks, cooperative threads and preemptive threads with a host processing environment; a scheduler configured to determine an execution order of cooperative threads and preemptive threads based on each cooperative thread's and preemptive thread's priority levels.

Abstract: A finite state machine in a portable thread environment is disclosed. In one embodiment, a system comprises a finite state machine operating within a portable thread environment; and one or more PTE message generators configured to pass state information contained in PTE messages to the finite state machine, wherein the finite state machine changes states according to the state information.
