instruction format

基本解釋

In fact, the largest length available for a memory address to any instruction format is only 24 bits!
實(shí)際上，內(nèi)存地址對(duì)于任何指令格式可以使用的最大長(zhǎng)度只有 24 位！
This is just to point out why instruction format matters on the PowerPC processor -- you need to know how much space you have to work with!
這只是為了說明為什么指令格式在 PowerPC 處理器上是如此重要 —— 您需要知道自己到底需要使用多少空間！
To learn how addressing modes work for load and store instructions on PowerPC processors, you must first understand a little bit about the PowerPC instruction format.
為了解尋址模式對(duì)于 PowerPC 處理器上的加載和存儲(chǔ)指令是如何工作的，我們必須先要對(duì) PowerPC 指令格式有點(diǎn)了解。
