Which of the following best names the concept in which a CPU performance technique that guesses the outcome of a conditional instruction before it is known?
Difficulty: Hard
About this MCQ
This Hard Computer Architecture MCQ checks one syllabus fact.
The question is: “Which of the following best names the concept in which a CPU performance technique that guesses the outcome of a conditional instruction before it is known?”
The accepted answer is B. Branch prediction. Branch prediction is the person body or term that satisfies Which of the following best names the concept in which a CPU performance technique that guesses the outcome of a conditional instruction before it is known option B Option A Von Neumann bottleneck does not match the stem it is a near-miss used to catch incomplete recall of Branch prediction Option C Clock cycle does not match the stem it is a near-miss used to catch incomplete recall of Branch prediction Remaining alternatives Accumulator fall outside the same rule and should be eliminated once Branch prediction is identified Computer Architecture questions of this type reward precise definitions rather than approximate associations Computer Architecture recall of this distinction is a regular.
