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.
