unspecified issues as you can a data into the and give 21.2 DES: data write. In the DES block, we included inputs for writing cipher block storage, but did not include that logic in the partitioned diagram (Figure 2 Update the block diagram to include the ability to read in data. Specify how this works 21.3 DEs: interrupt. In the DES specification and block diagram, add an put interrupt that stops DES computation. Be sure to specify the values of the outputs on interrupt, the does the system goes into, and what happens during the interruption of data input. How execution resume? 21.4 DES: Plaintext output. At the end of cracking, we would like to output the plaintext data. Specify this feature and include it in the partitioned block diagram
