Definition of "branch instruction" |
A branch is an instruction in a computer program that may, when executed by a computer, cause the computer to begin execution of a different instruction sequence. Branch (or branching, branched) may also refer to the act of beginning execution of a different instruction sequence due to executing a branch instruction. A branch instruction can be either an unconditional branch, which always results in branching, or a conditional branch, which may or may not cause branching depending on some condition. / an instruction is used to modify the instruction execution sequence of the CPU. The transfer of control to another sequence of instructions may be unconditional or conditional based on the result of a previous instruction. In the latter case, if the condition is not satisfied, the transfer of control will be to the next instruction in sequence. It is equivalent to a jump instruction, although the range of the transfer may be limited in a branch instruction compared to the jump. |
