寄存器

The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。

The shift register is a sequential logical circuit, which can store and shift binary digit information.

移位寄存器是用来寄存二进制数字信息，并能将存储的信息移位的时序逻辑电路。

This process is called register allocation and is one of the most important optimisations on all architectures, but it is even more important on the Intel architecture because of the low number of available registers.

这个处理叫做寄存器分配，它是所有体系结构中最重要的优化之一。因为寄存器数量很少，因此在 Intel 体系结构中它显得很重要。

Before making any timing to evaluate the effect of the two optimisations it is a good idea to optimise away some, or all if possible, of the stack to register and register to stack moves.

在比较这两个优化的效率之前，最好能尽可能的优化掉比如堆栈到寄存器，寄存器到堆栈的数据移动。

Therefore, in setting up the correspondence between register and location values, we can safely ignore those registers that are dead at the current point l.

所以，在设定寄存器及其分配单元之间的对应关系时，我们可以安全地忽略当前点l的所有非活跃寄存器。
