Abstract
A technique for processing strong ordered transactions in a direct memory access engine may include retrieving a memory descriptor to perform a strong ordered transaction, and delaying the strong ordered transaction until pending write transactions associated with previous memory descriptors retrieved prior to the memory descriptor are complete. Subsequent transactions associated with memory descriptors following the memory descriptor are allowed to be issued while waiting for the pending write transactions to complete. Upon completion of the pending write transactions, the strong ordered transaction is performed.
