In base index addressing mode how many number of cycles for operand fetch is to be required?

is it 8 ?

Assume

4cycles =consumed for memory reference

2 cycle = consumed for arithmetic operations

1cycle =consumed when operand present in register

0 cycle = consumed when operand present in instruction itself

 

Indexed

Add R3, (R1 + R2)

R3 <- R3 + M[R1+R2]

Useful in array addressing:
R1 - base of array
R2 - index amount
