Reference no: EM13339930

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 ?o16-bit memory???
b. What is the maximum memory address space that the processor can access directly if it is connected to an ?o8-bit memory???
c. What architectural features will allow this microprocessor to access a separate ?oI/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.
