Abstract
A processing unit of a packet processing node initiates a transaction with an accelerator engine to trigger the accelerator engine for performing a processing operation with respect to a packet, and triggers the accelerator engine to perform the processing operation. The processing unit attempts to retrieve a result of the first processing operation from a memory location to which a result is to be written. It is determined whether the result has been written to the memory location, and when it is determined that the result has not yet been written to the memory location, the processing unit is locked until at least a portion of the result is written to the memory location.
