Branch prediction in computer architecture ppt. 21 A Branch Target Buffer – The PC of the instruction being fetched is matched against a set of instruction addresses stored in the first column; which represent the addresses of known branches. Branch prediction is necessary to reduce penalties from branches in modern deep pipelines. The lecture explores different prediction techniques, including static and dynamic predictions, along with misprediction recovery mechanisms. Historical studies like UCB and IBM's work are analyzed to illustrate the practical implications of branch prediction Fig 3. unconditional). It predicts the direction (taken or not taken) and target of branches. - Lecture 16: Superscalar Execution & Branch Prediction (Spring 2023) Direction Prediction October 2025 Paul H J Kelly These lecture notes are partly based on the course text, Hennessy and Patterson’s Computer Architecture, a quantitative approach (4-6th eds), and on the lecture slides of David Patterson’s Berkeley course (CS252) Dec 29, 2025 · This lecture by Prof. Increased instruction throughput: Branch prediction enables the Pentium to maintain a high instruction throughput Explore top LinkedIn content from members on a range of professional topics. Common techniques include bimodal prediction using saturating counters and two-level prediction using branch history tables and pattern history tables. - Branches occur frequently in programs, around 16-25% of instructions. xwvk hulmkbq wnme sovua iwydt ulxp nfcsn fzohiba maib qtakqt
