Abstract
A branch prediction mechanism for predicting the outcome and the branch target address of the next possible branch instruction of a current instruction. Each of the entry of the branch target buffer (“BTB”) of the present invention provides a next possible branch instruction address, and the corresponding branch target address. By checking the TAG portion of each entry of the BTB with the current instruction address, the branch prediction mechanism can predict the next possible branch instruction and the corresponding branch target address.
