1. Suppose the hypothetical processor of Figure 1.3 also has two I/O instructions: 0011=LoadAC from I/O 0111 = 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: 1. Load AC from device 5. 2. Add contents of memory location 940. 3. Store AC to device 6 . Assume that the next value retrieved from device 5 is 3 and that location 940 contains a value of 2
