ASSIGNEMENT-2
LAST DATE OF SUBMISSION: 12/09/2012 PLACE: LHC 309
NOTE: WRITE THE ASSIGNEMENT IN THE NIST BOOKLET ONLY
1. What is the operating frequency for 8086 microprocessor?
2. How many address lines dose an 8086 have? How many addresses dose this
number of address lines allow the 8086 to access directly?
3. At any given time, the 8086 work with how many segments in this address space.
How many bytes are contained in each segment?
4. Make a list of the general purpose registers of the 8086 and defined the dedicated
operations assigned to each register?
5. List the segment registers of 8086 and mention what kind of information stored in
these registers.
6. Categorize the flag bits of the 8086 microprocessor and describe its functions.
7. Can the state of the flags be modified through software?
8. What is physical address? What are the two address elements combined to form a
physical address? Give the necessary hardware structure to generate physical
address.
9. If the current values in the stack segment register and stack pointer are C000H
and FF00H, respectively, what is the address of the current top of the stack?
10. What physical address is represented by?
4370H: 562EH
7A32H:0028H
11. What is memory segmentation? What are its advantages?
12. Explain in detail with necessary diagram about the Hardware memory
organization (physical memory organization) of 8086 microprocessor? How many
bus cycles are required to access a word at odd address?
