下载了 ARM 汇编编程网站的离线文档，此文档基于一个余从未见过的操作系统 RISC OS，但基本的东西如指令集是跨越厂商和平台的，汇编格式等差异应当不是大问题。余从中选译了指令集部分，没有选取依赖于特定硬件和工具的内容，并附加了余翻译的另一篇短文“ARM 指令格式和时序”。余对明显的错误进行了订正，并对部分内容做了一些必要的修改，好在改动的地方不是很多。余乃一介草莽，难免疏失错讹，祈望仁者指正。-downloaded compilation ARM website offline programming documents, based on this document I have never seen one of the RISC OS operating system, but the basic things like instruction set across vendors and platforms, the compilation format differences should not pose a big problem. I Made from the instruction set, not dependent on a specific selection of hardware and tools, and I added a translation of a message from another "ARM instruction format and timing." I obviously wrong for a revised, as well as part of a number of necessary changes, changes in the Fortunately, not many. I was just a wild, it is inevitable that mistakes Errors reliefs and benevolent correct.
