For hashing operations, the DCP module writes the final hash value back to the start of the
payload area for descriptors with the HASH_TERM bit set in the control packet. It is
important that software allocates the required payload space, even though it is not required
to set up the payload for control purposes.
13.2.7 Programming DCP Functions
13.2.7.1 Basic Memory Copy Programming Example
To perform a basic memcopy operation, only a single descriptor is required. The DCP
simply copies data from the source to the destination buffer. This process is illustrated in
the following figure.
