Figure 14-1 shows the module architecture, which consists of primary blocks. The DES module includes a register interface and a µDMA and interrupt interface.
Depending of the availability of context and data, the DES engine is automatically triggered to process the data. The DES engine is directly connected to the context and data registers such that it can immediately start processing when all data is available.
Packets (blocks of 64 bits) must be parsed into blocks and sequentially fed into the DES, which can buffer the block currently being processed as well as an additional block that may be queued in advance.
