Channel Privacy and Synchronization

Channel Privacy and Synchronization

Algorithms have exclusive ownership of each received logical channel and can operate safely without fear of external components (such as other algorithms or other system code) accessing the channel and issuing transfer requests or changing channel configuration settings. They must, however, follow the ACPY3 API to activate and deactivate each IDMA3 channel during instance activation and deactivation, respectively.

All synchronization calls are issued on a per channel basis, as opposed to a per transfer basis. An algorithm can issue either a blocking wait, or a non-blocking query call to synchronize with a logical channel’s completion status.
