Program to Shift Right 8-bit By 1-bit

Q. Write an 8085 program and draw a flowchart to Shift Right 8-bit By 1-bit.(8085 Microprocessor Program)

Flowchart/Algorithm

Program

Address	Mnemonics	Operand	Opcode	Comments
2000	LDA	3000H	3A	Load H-L pair with data from 3000H.
2001			00
2002			30
2003	RAR		1F	Shift right accumulator
2004	STA	3001H	32	Store the result at memory location 3001H.
2005			01
2006			30
2007 a	HLT		76	Halt

Output

Before Execution:

3000H: 04H

After Execution:

3001H: 02H

Program Explanation

This program performs the right shift operation on an 8-bit number by one bit stored in memory location 3000H.
Let us assume that the operand stored at memory location 3000H is 04H.
The operand is moved to accumulator from memory location 3000H.
Then, shift right operation is done by using RAR instruction.
The result is stored at memory location 3001H.
