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. What is the maximum memory address space that the processor can access directly if it is connected to a “16-bit memory”? What is the maximum memory address space that the processor can access directly if it connected to an “8-bit memory”? What architectural features will allow this microprocessor to access a separate I/O spece?
