Device Size Desired Base Address
ROM (27C64)8 KB $0000
RAM (6116)2 KB $4000
Input (74LS244)1 Byte $6000
Output (74LS374)1 Byte $7000
Which one of the following does NOT reflect the characteristics of the mapping possessed by the microprocessor system above?
I. With the mapping, not all instructions which reference to memory can be used
for I/O devices
II. The mapping has specific/dedicated instructions to communicate with I/O
devices
III. The mapping takes space (for I/O devices) from the main memory, reducing the
available memory
IV. With the mapping, any I/O devices are treated as memory locations on the map
V. With the mapping, any I/O devices use separate memory space
Question 25 Answer
a.
I, II, and V only
b.
I and II only
c.
