A data processing systemis provided with branch prediction circuitryfor performing branch prediction operations. Next branch table circuitrystores data identifying from a given branch instruction what will be the address of the next branch instruction to be encountered within the program flow. This next branch instruction address is supplied to the branch prediction circuitrywhich uses it to form its prediction prior to that next branch instruction being identified as such by the instruction decoder. This permits branch prediction to commence earlier in the branch prediction circuitrythan would otherwise be the case.
