3.3. 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.
