When we design an ISA, we may have some tradeoffs which you should identify in the following.

a$)(5$ points$)$ Having large number of registers available would reduce the number of spilling to

memory. What would be the downside of having large number of registers?

b$)(5$ points$)$ Complex Instruction Set Computer $($CISC$)$ ISAs often have very specialized

instructions that can perform multiple operations within a single instruction, which may reduce the

number of instructions needed for a program. What would be the downside of having such

specialized CISC$-$like instructions?
