The Dual-Ported Memory Manager provides a mechanism for converting addresses between internal and external representations for multiple dual-ported memory areas (DPMA). The directives provided by the Dual-Ported Memory Manager are:
rtems_port_create() - Creates a port.
rtems_port_ident() - Identifies a port by the object name.
rtems_port_delete() - Deletes the port.
rtems_port_external_to_internal() - Converts the external address to the internal address.
rtems_port_internal_to_external() - Converts the internal address to the external address.
