Advanced RISC machines (ARM) assembly language programming

大多数开发人员使用 C 和 C++ 等高级语言编写大部分代码。然后将此高级源代码编译为在目标设备上运行的机器代码。
然而，有时编写低级汇编代码也有优势。也许您想手动优化关键算法以使其尽可能快。或者您可能需要维护已经用汇编语言编写的遗留代码。或者，也许您只是想更多地了解代码的低级操作，以了解更多关于它是如何工作的。
在所有这些情况下，您都需要了解如何读写 Arm 汇编代码。汇编指令是任何程序的基本构建块。如果您要编写汇编代码，您将需要了解您可以使用哪些指令。
特定设备的精确可用指令集称为指令集。Arm 架构支持三种指令集架构 (ISA)：A64、A32 和 T32。使用这些资源

使用 ISA 探索工具以易于浏览的 XML 和 HTML 格式发现可用的 A64、A32 和 T32 指令。
请参阅 Arm 架构参考手册（A-profile、R-profile 和 M-profile）以获取明确的 ISA 详细信息。

Description
Students will learn the basics of ARM Programming
Most developers write most of their code using a high-level language such as C and C++. This high-level source code is then compiled into machine code that runs on a target device.
Sometimes, however, writing low-level assembly code has advantages. Perhaps you want to hand-optimized a critical algorithm to make it as fast as possible. Or perhaps you need to maintain legacy code that is already written in assembly. Or maybe you just want to learn more about the low-level operation of your code to understand more about how it works.
In all these situations, you will need to understand how to read and write Arm assembly code.Assembly instructions are the fundamental building blocks of any program. If you are going to write assembly code, you will need to understand what instructions are available to you.
The precise set of available instructions for a particular device is called the instruction set. The Arm architecture supports three Instruction Set Architectures (ISAs): A64, A32, and T32. Use these resources for more information
Learn more about the different instruction sets supported by the Arm architecture.
Use the ISA exploration tools to discover the available A64, A32, and T32 instructions in easy-to-browse XML and HTML formats.
Refer to the Arm Architecture Reference Manuals (A-profile, R-profile, and M-profile) for definitive ISA details.
