If the lk bit is 1 , the branch instruction moves the program counter to the address in lr 如果lk为1 ,转移指令就会将程序计数器移为lr中的地址。
Certain branch instructions can automatically load the lr to the instruction following the branch 某些转移指令可以自动加载lr到转移之后的指令。
Block whereas the ordinary branch instructions can only be used in such a block to transfer control within it 块,而一般分支指令只能在此类块中使用以在其内部转移控制。
Branch instructions using the contents of the link register or count register to specify the branch target address 使用链接寄存器或计数寄存器来指定转移目标地址的转移指令。
The ability to save the address of the next sequential instruction is provided on all branch instructions , including the branch to link register instruction 所有的转移指令都具备保存后继顺序指令地址的能力,包括到链接寄存器的转移。
In response to receiving a search address , multiple sets in the tag ram are simultaneously searched for a branch instruction that is predicted to be taken 根据所接收到的搜寻位址,在标签记忆体中会同时搜寻多个集合内分友指令是否会发生。
One supports branch instructions . the other does n ' t . and they both lack features common to general purpose microprocessors such as logic instructions and indirect memory access Gcx支持两类后端,一类不支持转移指令,另一类支持转移指令,但两者都缺乏一般微处理所具有的例如逻辑指令、存储器间接访问等特性。
The compiler passes profiling requests as a few bits of information in branch instructions to the hardware , and the processor executes profiling operations asynchronously in available free slots or on dedicated hardware 人们越来越把兴趣放到了运行时用实际输入数据进行文件配置和优化上。这样,这个程序就可以在运行时进行再优化,以适应“阶段”的改变。
To enable the selective access to the btb , the pht pattern history table in the proposed branch predictor is accessed one cycle earlier than the traditional pht if the program is executed sequentially without branch instructions 如果程序是在无分枝指令情况下顺序执行,为了使能对btb有选择性的访问,本文提出的分枝预测器中的pht要比传统的pht提早一个周期访问。
