The conventional architecture of a FlexRay node consists of four major blocks. Three of them are necessary and the fourth can be considered as optional. They are: the ‘host’ microcontroller, the protocol manager, the line driver, and finally, the ‘bus guardian’. It should be noted that, very often, the protocol manager and the host microcontroller form one and the same integrated circuit, and that today there are few solutions which use a bus guardian. The specifications dedicated to the FlexRay protocol describe in great detail the architectures that the interfaces of the host processor and protocol manager must have but also the necessary architecture that a node of the network must have to ensure that the network functions well. There will therefore be, as always, different hardware and pseudo software implementations, such that (i) they conform, (ii) they are interoperable and (iii) the consistency of the network is fully respected. driver circuits; microcontrollers
