Consider a hypothetical $32-$bit microprocessor having $32-$bit instructions composed of two fields. The first byte contains the opcode and the remainder an 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$1.)$ a $32-$bit local address bus and a $16-$bit local data bus, or$2.)$ a $16-$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?
