main memory register的意思|示意

For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.

例如，编译器为了优化一个循环索引变量，可能会选择把它存储到一个寄存器中，或者缓存会延迟到一个更适合的时间，才把一个新的变量值存入主存。

The PowerPC uses a load/store (also called RISC) instruction set, which means that the only time it accesses main memory is for loading into registers or copying a register to memory.

PowerPC 使用了加载/存储（也成为 RISC）指令集，这意味着访问主存的惟一 时机就是将内存加载到寄存器或将寄存器中的内容复制到内存中时。

In register mode, rather than accessing the contents of main memory, you access registers.

在寄存器寻址模式中，我们也不会访问主存的内容，而是访问寄存器。

Before an instruction is executed, it is first retrieved from main memory and pout into a register.

一个指令执行前，首先将其从主内存中取出并放如寄存器内。

Compared to traditional register-exchange and trace-back methods, the main advantages of this method lie in less memory and little decoding delay.

在此提出了一种幸存路径存储器的新实现方法，与传统的回溯法和寄存器法相比，该方法具有存储器用量少、译码延迟小的特点。
