指令

A new very long instruction word machine model was described and analyzed. In order to exploit the parallelism in this model, a software bypass method based on static single assignment and an integrated operation-based instruction scheduling and register allocation algorithm were presented.

描述并分析了一种新型的VLIW机器模型，为充分利用该模型的并行特性，提出了基于静态单一赋值表示的软件旁路方法，以及集成的基于操作的指令调度与寄存器分配算法。

Commentary: ICWS'86 clearly states the use of an instruction register, but the other operand address and value registers are only implied.

注释： ICWS'86清楚说明指令寄存器的使用，但其他操作数地址和数值寄存器都只是隐含的。

Previous work on register pressure sensitive instruction scheduling generally scheduled instructions conservatively when there were too many live variables in the scheduling region.

前人的寄存器压力敏感的指令调度的方法，往往当调度区域内活跃变量个数超过阈值时一味保守地调度。

LSPn. This control block receives input from the STA111 instruction register, mode registers, and the TAP controller.

。这个控制块接收来自STA111指令寄存器的输入，模式寄存器和TAP控制器。

In IEEE Std 1149.1, the boundary-scan description language depicts the length and structure of the boundary-scan register, the instruction binary codes and the device-identification code etc.

在IEEE 1149.1标准中，边缘扫描描述语言描述了边缘扫描寄存器的长度和结构、指令的二进制代码及器件标志代码等。

Instructions can be prefixed with the name of one of the predicate registers, and the CPU will only execute the instruction if the register equals True.

即只有相应的断言寄存器中值为"真"时CPU才会执行指令，不然CPU就执行一条

There are several types of registers ,Including an instruction register , which holds the instruction being executed ,an address register, which holds the addresses of data to be processed ;a program register , which holds status information ; and an accumulator , which holds the results of the ALU's

寄存器有几种类型，包括指令寄存器，它含有将要被执行的指示，地址寄存器，它包含被处理的数据地址；程序寄存器，它包含程序的状态信息；还有累加器，它包含算术\逻辑运算单元的操作结果。

The execution environment described here includes memory, general purpose data registers, segment registers, the flag register, and the instruction pointer register.

此处描述的执行环境包括内存、通用目的数据寄存器、段寄存器、标志寄存器和指令指针寄存器。

Assumingthat your mi_switch hook is going to be installed on a wide range ofsystems, you can use the fact that mi_switch always accesses /*1*/ the%fs segment register as yourplaceholder instruction.

假设你的mi_switch 挂勾计划可以安装在大范围的系统，你可以利用一个事实，mi_switch 总是访问%fs段寄存器(当然，它是curthread)，做为你的指令占位符。

You can also use the name of a segment register as an instruction prefix: coding es mov ,ax is equivalent to coding mov ,ax.

你也可以用段寄存器名作为指令前缀：代码 es mov ，ax等价于mov ，ax。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
