$1-$ Consider two microprocessors having $8-$ and $32-$bit$-$wide external data buses, respectively. The two processors are identical otherwise and their bus cycles take just as long.

a$.$ Suppose all instructions and operands are two bytes long. By what factor do the maximum data transfer rates differ?

b$.$ Repeat assuming that half of the operands and instructions are four bytes long.

$2-$ Consider a hypothetical $32-$bit microprocessor having $32-$bit instructions composed of two fields: the first byte contains the opcode and the remainder the immediate operand or an operand address.

a$.$ What is the maximum directly addressable memory capacity $($in bytes$)?$

b$.$ Discuss the impact on the system speed if the microprocessor bus has

$32-$bit local address bus and a $16-$bit local data bus, or

$16-$bit local address bus and a $16-$bit local data bus.

c$.$ How many bits are needed for the program counter and the instruction Register?

$3-$ What is the Size of the register and operands in RV$32$ and RV$64?($SOLVE ALL QUESTIONS ON PAPER WITH STEPS$)$
