ARM汇编语言(Assembly Language)是ARM CPU所能接受的最底层唯一语言(所有的高级语言最终都要转换成汇编语言然后汇编成processor instruction codes)。ARM汇编的核心是ARM指令集。理解ARM汇编有助于理解底层processor内部的工作原理,有助于对高级语言的优化。由于ARM汇编小、快的特点,经常被用在processor的初始化配置中(常见...

Immediate post-indexed addressing is another addressing mode. To indicate this mode in assembly language, we follow the brackets with a comma and a positive or negative immediate. In executing the instruction, the processor still accesses the memory address found in the register, but after ...
Wilson subsequently rewrote BBC BASIC in ARM assembly language. The in-depth knowledge gained from designing the instruction set enabled the code to be very dense, making ARM BBC BASIC an extremely good test for any ARM emulator. 参考译文:ARM的第一个应用是作为BBC Micro的第二处理器,它在开发...
ARM assembly language is designed specifically for the Instruction Set Architecture (ISA) of ARM processors, known for its prevalence in mobile devices, embedded systems, and diverse computing environments. Offering direct access to registers, versatile addressing modes, and portability across different ...
The assembly syntax separates offset from the the scale with a comma, which looks a bit odd. A more natural-looking syntax would be ldr r0, [r1, r2 lsl #2] ; r0 = *(r1 + (r2 << 2)) to emphasize that thelsl #2is applied tor2. But the syntax is what it is, and you just...
The term addressing mode is interpreted broadly in this manual, to mean a procedure shared by many different instructions, for generating values used by the instructions. For four of the addressing modes described in this chapter, the values generated are memory addresses (which is the traditional...
Addressing Modes: Exploring different addressing modes in ARM 64-bit assembly and how they are used to access memory. Function Calls and Stack Management: Writing and calling functions, managing the stack, and understanding calling conventions. ...
.ascii “<string>” Inserts the string as data into the assembly (like DCB in armasm)..asciz “<string>” Like .ascii, but follows the string with a zero byte..balign <power_of_2> {,<fill_value> {,<max_padding>} } Aligns the address to <power_of_2> bytes. The assembler ...
