寄存器

The Instruction Register holds the bit pattern that represents the current instruction; different parts of the bit pattern are used to encode the "operation code" and the address of any data required.

指令寄存器保持着二进制位组合格式表示的当前正在执行的指令。在这个二进制位组合格式中，不同的部分被相应的用来编码"操作代码"以及操作所需数据的地址。

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。

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

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。

This section describes the requirements and use of the device bus operations, which are initiated through the internal command register.

这个章节描述了需求和怎样进行设备总线操作，而这些都是通过内部命令寄存器进行初始化的。

Programming is accomplished via the internal device command register and is a four-bus cycle operation.

通过编程实现内部器件命令寄存器，是一个四总线周期操作。

This paper introduces the STACK architecture of SPARC and the operation to Windows Registers. Then gives an example of context switching function and interrupt handler based on uC/OS.

本文简单介绍了SPARC的栈结构、寄存器窗口的相关操作，并以uC/OS的移植为例子，简单实现了切换函数以及系统时钟中断。

More modern hardware often has one or more interrupt status registers that latch the interrupt requests; well written edge-driven interrupt software often checks such registers to ensure events are not missed.

写得好的沿驱动中断软件通常检查这些寄存器以确保不会丢失事件。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
