Question: How many times will a CPU have to reference memory in order to fetch and execute a two-word indirect addressing mode instruction (a) if the instruction is an ADD instruction requiring one operand from the memory location referenced by the indirect addressing-mode and the other operand from a CPU register, returning the result of the ADD back to the memory location (i.e. a "read-modify-write" type instruction)?
Q: How many times will the CPU have to reference memory in order to fetch and execute a two-word indirect addressing mode instruction (b) if the instruction is a JMP instruction?
Find the how many times the CPU will have to reference memory and execute a two-word indirect addressing mode.
