Distributed Control Computer Backbone Communication Channel of Electric Locomotive with effective DMA support

Popis výsledku v původním jazyce

The architecture of the backbone communication channel of the electric locomotive distributed control computer is presented. Without need to connect third party devices into the vehicle internal local kernel of distributed control computer simple but reliable and high speed communication NBP protocol can be efficiently used. Communication services are embedded into the real time operating system. The operating system is highly scalable so that communication services can be used outside the RTOS. Minimized but user friendly API's are designed. Internally up/down dual communication cycle is used. It is based on DMA transfer from/to user communication message queues with two levels of transfer priorities. No communication processor is used. All network activities are processed by application (host) processor only. The host processor overhead by network communication is minimized to several percent
