MICROPROCESSORS AND INTERFACING LAB

I. Microprocessor 8086 :

 

1. Introduction to MASM/TASM.

2. Arithmetic operation – Multi byte Addition and Subtraction, Multiplication and Division – Signed and

unsigned Arithmetic operation, ASCII – arithmetic operation.

3. Logic operations – Shift and rotate – Converting packed BCD to unpacked BCD, BCD to ASCII

conversion.

4. By using string operation and Instruction prefix: Move Block, Reverse string, Sorting, Inserting,

Deleting, Length of the string, String comparison.

5. DOS/BIOS programming: Reading keyboard (Buffered with and without echo) – Display characters,

Strings.

 

II. Interfacing :

1. 8259 – Interrupt Controller : Generate an interrupt using 8259 timer.

2. 8279 – Keyboard Display : Write a small program to display a string of characters.

3. 8255 – PPI : Write ALP to generate sinusoidal wave using PPI.

4. 8251 – USART : Write a program in ALP to establish Communication between two processors.
