指示事件完成之前已执行的分支指令的个数。
Indicates the number of branch instructions executed until the event is completed.
分支提示至少是分支指令之前的4个指令取出组，否则就没有效果。
At minimum, the branch hint must be four instruction fetch groups before the branch instruction, or it will have no effect.
分支预测算法的研究包括分支历史信息的处理，分支指令地址的映射，状态转换等。
The research on branch prediction includes the use of history information, branch instruction address mapping and state transition.
通过分支指令访问条件结构的False部分，这不是最优的方式，但是访问它的可能性不大。
The False portion of the conditional would then be available through the branch instruction, which is less optimal but also less likely.
传统的软件容错技术频繁使用和比较分支指令检测错误，带来了巨大的性能和功耗的开销。
Traditional software fault tolerance USES a great deal of branch instructions to detect errors, thus brings great overhead in both performance and power dissipation.
要想让分支提示变得非常有效(这样分支就根本不会暂停了)，就必须设置至少4个指令取出组和分支指令之前的11个周期。
For a branch hint to be most effective (so that the branch does not stall at all), it must be set at least four instruction fetch-groups plus 11 cycles before the branch instruction.
例如，如果一个条件标上了“likely”，那么编译器可以把代码的True部分直接放在分支指令后面(这样就不需要执行分支指令)。
For example, if the conditional is marked "likely" then the compiler can place the True portion of the code immediately following the branch (which will not be taken).
另外，如果希望使用某条特定指令而不希望编译器来选择指令，那么可以使用specific intrinsic来执行几乎所有的非分支指令。
In addition, if you want a specific instruction rather than having the compiler choose one, you can perform almost any non-branching instruction with the specific intrinsics.
hbr hint_trigger, $register ——告诉处理器相对地址 hint_trigger 处的分支指令可能会跳转到寄存器 $register 所指定的地址。
hbr hint_trigger, $register -- This tells the processor that the branch instruction at the relative address hint_trigger is likely to branch to the address specified in register $register.
这让处理器可以提前准备分支操作（例如预取指令）。
This allows the processor to prepare for the branch ahead of time (prefetching the instructions, for instance).
如您所见，这段代码更加简单——分支更少，指令也更少。
As you can see, the code is much simpler — it has fewer branches and fewer instructions.
brsl代表“branch relative and setlink”，用来分支到函数的入口点并将链接寄存器(LR)设置为返回地址的下一个指令。
BRSL stands for "branch relative and set link." This branches to the function entry point and sets the link register (LR) to the next instruction for the return address.
下面是3条分支提示指令。
分支预测错误(处理器猜错了分支，所以它不得不更新流水线并从正确的分支装载指令)。
Branch mis-prediction (Processor guesses the wrong branch, so it has to flush the pipeline and load instruction from proper branch again), or.
问题的关键是SPU有几个条件指令，例如selb、shufb和位操作，它们可以不用分支就能实现条件操作。
The key is that the SPU has several conditional instructions, such as selb, shufb, and the bit operations, which allow conditional operations to occur without branching.
这是一种用于示出核因其正在指令流错的误分支上工作而没有做出许多“有用”工作的良好指示器。
This is a good indicator to show that the core is not doing lots of "useful" work since it is working on the wrong branch of instruction stream.
分支转移指令的典型示例有call、return和jump。
Typical examples of branch instructions are call, return, and jump.
如果下列指令的目标是一个分支，这个目标的计划可能会崩溃。
If the following instruction is the target of a branch, the target program may crash.
