 Each MWMR (Multi-Writer Multi-Reader) channel can be accessed concurently by one or several writer(s) and by one or several reader(s). It is implemented as a software FIFO, protected by a build-in lock.
 
-This software FIFO can be directly accessed by an hardware coprocessor, thanks to the vc_mwmr_controller, but be describe here the the software API that can be used by a software application.

 WARNING (i) The max number of words that can be stored in a MWMR channel is 1018 words (4072 bytes), because  the mwmr_channel_t object has a fixed size (4Kbytes in the present implementation).
