Question

5. 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 processor can access directly if it
is connected to an “8-bit memory”?
c. What architectural features will allow this microprocessor to access a separate “I/O
space”?
d. If an 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
