What is an OCP transfer?
There are in OCP 1.0 two types of transfers, a posted write transfer and a read transfer. When an OCP initiator issues a write request to an OCP target, it also specifies an address where the slave should store the data associated with the request. When the slave receives the request, address and data, a posted write transfer has occurred. Likewise, when a master issues a read request to an OCP target, it also specifies an address from which to fetch the data associated with the request. When the master receives the data, a read transfer has occurred. Finally, OCP defines a broadcast transfer which is similar to a write transfer but is intended to be relayed to multiple entities that connect to the receiving slave interface.
