Coordination Logic

OpenRG is designed as a single threaded client application. The coordination logic component, Main Task, is the application that evokes life in the functional modules. In essence, it is the system's core. The single-threaded design has numerous benefits, mainly:

• OpenRG can operate on embedded RTOS's.
• OpenRG can be easily ported to other operating systems.
• Inter Process Communication (IPC) is simplified - functional tasks communicate with the Main Task using a simple function call. Conversely, ordinary multi-process design involves information packaging, IPC tunneling and parsing by the receiving side.
• Context switches are minimized.
• Memory footprint is reduced by linking all of the modules together, eliminating code needed for IPC, configuration and synchronization.
• Synchronization issues between processes/threads are avoided. Tasks cannot be interrupted while processing - only when waiting for a callback.
• Debugging is easier - system execution can be traced from the initial Web-based management button click, all the way down to the actual low-level operation.
