Question 3: (20 marks) Suppose we have the following code: Add 400 Load 300 Knowing that AC=400 before executing the two instructions, and the memory and register R1 containing the values below, determine the actual value that will be found in the accumulator AC after executing each instruction in each mode, and fill in the table below: Note that for each addressing mode the value of AC is initially 400, and the value of the next instruction in each mode might depend on the previous instruction result. 100 200 Mode Value in AC after Add 400 Value in AC after Load 300 200 400 R1 200 300 600 400 300 Immediate Direct Indirect Indexed 500 100 600 400 700 300 1000 300
