)Suppose the hypothetical processor of Figure 1.3 (the hypothetical machine discussed in class) also has two I/O instructions: 1001 = Load AC from 10 010 Store AC to I/O In these cases, the 12-bit address identifies a particular external device. Show the program execution (using format of Figure 1.4) for the following program: a) Load AC from I/O device 5 b) Add contents of memory location 940 c) Store AC to I/O device 6 Assume that the next value retrieved from device 5 is 20 and the memory location 940 contains a value of 18
