problem 1: Design an Input-Output port decoder which generates the following low-bank Input-Output strobes:
00FEH, 00C8H, 00DEH, 00EEH
problem 2: Describe the given data transfer schemes:
a) Programmed I/O.
b) Interrupted I/O.
problem 3: Why do we prefer interrupt driven data transfer than programmed Input-Output transfer?
Also show the complete hardware design to resolve the multiple interrupts based on priority?
