SECURE AND EFFICIENT APPLICATION DATA PROCESSING

A system architecture is provided and includes first and second processing units respectively communicative with an on-chip coherency unit and an accelerator communicative with the on-chip coherency unit. The accelerator is configured to execute an operation responsive to a call issued by one of the first and second processing units. The first processing unit is configured to set an asynchronous operation flag (AOF) to indicate that the second processing unit is to conduct an operation for the first processing unit. The second processing unit is configured to respond to the AOF by building scatter gather lists and subsequently issuing the call and feeding the scatter gather lists to the accelerator to facilitate execution of the operation by the accelerator.
