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
