Branch Handling

Branch handling is an effective technique used in computing to optimize performance by dividing complex tasks into smaller, manageable sections. It involves splitting a single thread of execution into multiple branches, each responsible for a specific subtask. This approach improves efficiency by allowing processors to work on multiple tasks simultaneously.

Why Learn Branch Handling?

Learning branch handling offers several benefits, including:
