Název v původním jazyce

Efficient DMA Based Local Computer Network Communication Services for Traction Vehikle

Popis výsledku v původním jazyce

The architecture of local computer network of traction vehicle (electric locomotive) is considered in this paper. With no need to connect third party devices into internal local kernel of distributed control computer of the vehicle, simplified but reliable and high speed communication protocol with NBP address/data bit feature can be efficiently used. Communication services are embedded into RT operation system. Minimized but user friendly API's are designed. Internally up/down dual communication cycleis used 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 processor only, its overhead by communication is minimized to several percent.
