Dynamic per-branch history length adjustment to improve branch prediction accuracy
Branch misprediction limits processor performance signiWcantly, as the pipeline deepens and the instruction issued per cycle increases. Since the introduction of the two-level adaptive branch predictor, branch history has been a major input vector in branch prediction, together with the address of a branch instruction. Until now, the length of branch history has been statically Wxed for all bra...
متن کاملThe Cascaded Predictor: Economic and Adaptive Branch Target Prediction
Two-level predictors improve branch prediction accuracy by allowing predictor tables to hold multiple predictions per branch. Unfortunately, the accuracy of such predictors is impaired by two detrimental effects. Capacity misses increase since each branch may occupies entries proportional to the number of different path histories leading up to the branch. The working set of a given program ther...
متن کاملApplying Caching to Two-Level Adaptive Branch Prediction
During the 1990s Two-level Adaptive Branch Predictors were developed to meet the requirement for accurate branch prediction in high-performance superscalar processors. However, while two-level adaptive predictors achieve very high prediction rates, they tend to be very costly. In particular, the size of the second level Pattern History Table (PHT) increases exponentially as a function of histor...
متن کاملA FFT-Based Adaptive Branch Prediction Scheme
We propose a scheme based on the concept of Fourier analysis to dynamically adjust the length of the global Branch History Register (BHR) used in several popular branch prediction schemes such as gshare [5] and BiMode [12]. The scheme allows us to identify the most dominating branch history patterns in a time period, and use them to determine the appropriate branch history length (BHL) for the ...
متن کاملExploring Dynamic Branch Prediction Methods
How to resolve the control flow breaking caused by the branch instructions is a major issue in modern deep pipeline processor design. Our project is based on the paper of J. Stark et. al. [1], a variable length path branch predictor. It uses the branch path information for prediction, and change the length of the path dynamically based on the profiling of the application. It shows that a “cleve...
