Hash Engine Real Time Verification
The Hash engine contains two hash cores to implement real time verification of the data.
For single File hash and Slice hash operations, both Hash cores calculate the hash/MAC
simultaneously and the two results are compared. If an error is detected it will be reported
to the host. For “File hash + Slice hash” operations, one core calculates the “File hash” and
the other core calculates the “Slice Hash”. Figure 2-5 shows the real time verification for
File hash and Slice hash operations.
