Figure 4-2. Encode Operation: Compression Engine before Hash Engine
4.1.3
Hash Engine after Pad Engine
Figure 4-3 shows the data flow when the Hash engine position is after the Pad engine and
all four engines are enabled. In this configuration, the Hash engine calculates the MAC
value of the compressed and padded data, CMP + Pad. The data flow for the remaining
engines is the same as described in Section 4.1.1, “Hash Engine before Compression
Engine".
