Abstract:
A branch prediction method, capable of predicting a first taken branch instruction within a plurality of fetched instructions, includes: determining whether one of the fetched instructions is the first taken branch instruction to be predicted according to hint instruction(s) or according to latest statistics of whether respective fetched instructions have been taken. The branch prediction method further includes: if one of the fetched instructions is determined to be the first taken branch instruction, performing branch prediction on the first taken branch instruction.
