What can loop unrolling techniques help reduce? a) Code size b) Execution time c) Compilation errors d) Cache misses
Understand the Problem
The question is asking about the benefits of loop unrolling techniques in programming. Specifically, it wants to know which of the given options (a, b, c, or d) loop unrolling can help reduce. Loop unrolling is commonly used to improve performance by decreasing the number of iterations and overhead in loop control, which can lead to reduced execution time and potentially improve cache performance.
Answer
b) Execution time
The final answer is b) Execution time
Answer for screen readers
The final answer is b) Execution time
More Information
Loop unrolling is a technique used to increase a program's execution efficiency by reducing loop-related overhead, such as the number of iterations and branches, which often leads to optimized execution speed.
Tips
A common mistake is assuming loop unrolling reduces code size; it actually increases it. The goal is to reduce execution time, not size.
