All jump and branch instructions occur with a delay of one instruction: that is, the instruction immediately following the jump or branch (this is known as the instruction in the delay slot) always executes while the target instruction is being fetched from storage. Branch-likely instructions are used for static branch prediction. The instruction in the delay slot is executed only when the branch is taken; the instruction in the delay slot is nullified if the branch is not taken.
