2.Consider a hypothetical microprocessor generating a 16-bit address (for example assume that the program counter and the address registers are 16-bits wide) and having a 16-bit data bus.

a) What is the maximum memory address space that the processor can access directly if it is connected to a "16-bit memory"?

b) What is the maximum memory address space that the process can access directly if it is connected to an "8-bit memory"?

c) What architectural feature will allow this microprocessor to access a separate "I/O space"?

d) If any input and an output instruction can specify an 8-bit I/O port number, how many 8-bit I/O ports can the microprocessor support? How many 16-bit I/O ports? Explain.
