RTOS add-on tackles comms in multiprocessor systems

摘要

Support for distributed and multicore systems can be provided by an optional RTOS component called a link handler. These add-ons offer an elegant general alternative to traditional network communication for asynchronous message passing between applications running on different processors. They do so by using the same asynchronous "direct" message-passing model as that used by an RTOS kernel for intraproces-sor task-to-task communications, extending it into the realm of distributed and multicore, multiprocessor systems to implement peer-to-peer relationships among the system processors.
