Assignment
Microprocessor and Micro controller
BATCH- EE-456, EE-789
SUBMISSION DATE - 21 Feb 2019
1. Design a microprocessor 8086 system having two 4K X 8 EPROM and four 8K X 8 RAM. Avoid any foldback addresses.
2. What do you mean by segment over ride prefix? Write the instruction format for
MOV DS: 2345 [BP], DX.
3. Differentiate memory mapped I/O and I/O mapped I/O?
4. What are the Logical and Physical addresses? How the physical addresses are generated ?
5. Interface Stepper Motor to 8086 using 8255 and write Assembly Language Program
to rotate Stepper Motor in Clockwise direction and in full stepping. Assume that
8255 is interfaced with 8086 in memory mapped IO.
6. What do you understand by assembler directives in 8086?
7. Write an ALP to produce a delay of 1 second. Consider the 8085 clocked at 5 Mhz.
8. Explain the following instructions (8086):-
(a) SCASB (b) LEA (c) AAA (d) CBW (e) TEST (f) STOS
