Which one of the following most correctly describes the functionality of the control unit in a CPU? To perform arithmetic operations based on decoded program instructions To store program instructions To perform logic operations based on decoded program instructions To generate control signals based on decoded program instructions When an interrupt occurs, which one of the following takes place? Execution of the current instruction is completed, and the address of the next instruction is saved before the interrupt service program starts Execution of the current instruction is aborted, and its address is saved before the interrupt service program starts Execution of the current instruction is completed, and the interrupt service program starts Execution of the current instruction is aborted, and the interrupt service program starts

2. Which of the following are components of a machine's state (value at the beginning of each instruction cycle determines what happens next)? Mark all that apply. - IR - Memory - PC - Registers - ALU 3. Which of the following instruction sequences result in R[A] having the value FFFF? Mark all that apply. - 7AFF - 7B08 - 5AAB - 6AAB - 7AFF - 7A01 - 2A0A - 7B01 - 2B0A - 7B01 - 2A0B 4. Suppose that the following sequence of instructions is loaded into memory locations 10-16: 10: 7COA 11: 7101 12: 7201 13: 1222 14: 2CC1 15: DC13 16: 0000 and you set the PC to 10 and press RUN. Give the decimal number represented by the contents of R[2] when the machine halts.
