[[PageOutline]]


The [source:soft/giet_vm/giet_drivers/mwr_driver.c mwr_driver.c] and [source:soft/giet_vm/giet_drivers/mwr_driver.h mwr_driver.h] files define the MWR driver.

The vci_mwmr_controller is a multi-channels hardware component that can be used to connect an hardware coprocesseur to one or several MWMR channels (software FIFOs implemented in memory). 
 * On the VCI side, it implements the five steps MWMR communication protocol.
 * On the coprocessor side, it implements as many FIFOs interfaces as the number of MWMR channels.

It is an ''internal'' peripheral, even if it is not replicated in all clusters. 

WARNING : The MWR driver is not available yet.
