Peculiar Peripherals, Inc. Builds a combinational encryption device constructed of nine modules as follows:

The device takes an integer value X and computes an encrypted version C(X). In the diagram above each combinational component is marked with its propagation delay in microseconds; contamination delays are zero for each component.

a. What is the latency and throughput of the combinational encryption?

b. Redraw the diagram marking the locations for ideal (zero-delay) registers that will pipeline the device for maximal throughput. Ensure a register at the output

and use the minimum number of registers necessary.

c. Give the latency and throughput of your pipelined version. Again assume ideal registers .
