I created a class definition of the hybrid predictor in the config-mixins.scala file and create a class instance in the BOOMConfigs.scala file. When I try doing that, the results I get are the same as if I run the benchmark programs (multiplication.riscv, qsort.riscv,...
Branch Predictor is a C# program that runs a gshare branch prediction simulation, according to a specified number of Global Buffer Table (GBT) and Global History Record (GHR) bits. 2019. branch-predictionbranch-predictorgbtghrglobal-branch-predictorglobal-buffer-tableglobar-history-recordgsharegshare-...
分支预测器(英语:Branch predictor)是一种数字电路,在分支指令执行结束之前猜测哪一路分支将会被执行,以提高处理器的指令流水线的性能。 条件分支指令通常具有两路后续执行分支。即不采取(not taken)跳转,顺序执行后面紧挨JMP的指令;以及采取(taken)跳转到另一块程序内存去执行那里的指令。 是否条件跳转,只有在该分支...
