 These functions are used to access coprocessors connected to the VCI network with a ''vci_mwmr_dma'' controller.

+They make the assumption that there is only one hardware coprocessor per cluster, and a coprocessor can be identified by the cluster coordinates.
 
 The following structure (defined in the stdio.h file) is used to define a specific TO_COPROC / FROM_COPROC channel.
