为了消除解释的高性能代价，JIT编译器选择将频繁执行的代码直接转换为CPU的本地指令。
To eliminate interpretation's high performance cost, a JIT compiler selects frequently executed code to be translated directly to the CPU's native instructions.
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.
TS(跟踪选择，Trace Selection)，每当样式表伪指令执行select操作以从源文档检索数据时就生成一条消息。
TS (Trace Selections) produces a message each time a stylesheet directive performs a select operation to retrieve data from the source document.
无论是采用哪种方式的编码或语言方法用来选择操作计算机，它都是基于一组由中央处理单元(CPU)执行的指令。
Whichever method of encoding or language is chosen to operate the computer, it's based on a set of instructions that are executed by the central processing unit (CPU).
它按主存储器里固定的步骤选择和检索指令，以便在适当的时刻激活系统的其它功能组件来执行相应的操作。
It selects instructions from the main memory in proper sequence and sends them to the instruction-decoding unit, which interprets them so as to activate functions of the system at appropriate moments.
当微处理器对该指令译码时，它确定处理的是哪一条指令以便选择正确的操作序列去执行。
When the microprocessor decodes the instruction, it determines which instruction it is in order to select the correct sequence of operations to perform.
正确的选择，取决于应用程序是否具有可以在作业完成时执行的指令。
The correct choice depends on whether the application has instructions that can execute while the operation completes.
有人曾经指出，这两个区域的相互作用可以通过正确选择和执行指令来完成。但目前科学家尚不清楚的是：这种相互作用是如何发生的。
Interaction between these regions has been proposed to underpin the correct selection and execution of motor commands, but it is not clear how such interactions occur.
为了简化他们选择在PC暴露当前指令的地址取指令，而不是当前正在执行的指令的设计。
To simplify the design they chose to have the PC expose the address of the current instruction fetch, rather than the currently executing instruction.
为了简化他们选择在PC暴露当前指令的地址取指令，而不是当前正在执行的指令的设计。
To simplify the design they chose to have the PC expose the address of the current instruction fetch, rather than the currently executing instruction.
