Program to Shift Right 8-bit By 1-bit

by

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

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