Suppose that a particular banking system supports encrypted transactions, and that decrypting

each transaction consists of three sub$-$tasks A$,$ B$,$ and C$.$ The execution times of each task on a

microprocessor versus a custom digital circuit are $50$ ms versus $1$ ms for A$,20$ ms versus $2$ ms for

B$,$ and $20$ ms versus $1$ ms for C$.$

Recommend a solution for the transaction that partitions $($divides$)$ the tasks among the

microprocessor and custom digital circuitry, such that you minimize the amount of custom digital

circuitry, while still meeting the constraint of decrypting at least $40$ transactions per second.

Justify your answer with calculations. Show calculations to find the optimum solution
