b) Find the sum of (-38) and (-68) in 8-bits binary representation using C1 representation. c) What can you say about the result? Discuss. 2. Suppose we have the following code: [10 marks] Add 400 Store 200 Knowing that AC=600 before executing the two instruction, 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 600 T103-TM103 / Final 3 of 4 Spring 2018-19 100 200 200 400 R1 200 300 600 400 300 Value in AC after Add 400 Value in AC after Store 200 500 100 Mode Immediate Direct Indirect Indexed 600 400 700 300 1000 300
