This allows you to have a set of registers which can be counted on to be preserved across function calls.

这就让您有一组寄存器可跨函数调用保留。

Generally, they start off with a "base" set of data that is known to be available to the program — stack data, global variables, and registers.

通常，它们以程序所知的可用的一组“基本”数据——栈数据、全局变量、寄存器——作为出发点。

A set of 128 registers, each 128 bits wide (each register is normally treated as holding four 32-bit values simultaneously).

一组128个寄存器，每个128位宽(每个寄存器通常都可以用来同时保存4个32位的值)。
