Time left 0:15:25 (Expected Time = 3 minutes) Which of the following statements is correct regarding recursive procedures? If implemented using iteration, return address must be pushed in the stack O The performance is better if the procedure is implemented using iteration instead of recursion If implemented using recursion, return address does not need to be pushed in the stack The execution time is higher if the procedure is implemented using iteration instead of recursion Which of the following statements is correct regarding code scheduling in the context of the 5-stage pipeline discussed in class? O It is legal for code scheduling to change the final output of the code Code scheduling improves the performance by eliminating some of the load-use data hazards O Code scheduling improves the performance by eliminating the need for forwarding it is guaranteed that every code can be scheduled to achieve better performance Which of the following statements is correct regarding the RISC-V 5-stage pipeline discussed in class? Pipelining improves the latency of Branch, R-Type, and Store instructions compared to Single-Cycle CPU O Pipelining and Single-Cycle CPU always have the same latency for any instruction O Compared to Single-Cycle CPU, Pipelining improves the number of instructions executed per unit of time Pipelining improves the latency of all instructions compared to Single-Cycle CPU
