Question

Multiplication of two 8 bit numbers in 8085 by rotation method

Answer 1

Multiply 110 =A by 101=B.  

In B, lowest number is 1.  

Move A to register.  

Shift register body left once.  

Second digit of B is zero.  

Not necessary to add A now so Shift left.

Test LSB of B which is 1.

Add A to register contents.  

Register now holds answer 1110 verify it in binary mode.  

Clear register.  

Answer 2
