所以主要功能先由C/ASM编写,然后根据需求改变部分机器码。 首先研究一下《Instruction Set Assembly Guide for Armv7 and earlier Arm®architecturesVersion 2.0Reference Guide》和《Arm A-profile A32/T32 Instruction Set Architecture》。 1. Conditional instruction A32每条指令的bit[31:28]表示需要满足的条件,...

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...
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...

The ISA provides the only way through which a user is able to interact with the hardware. It can be viewed as a programmer’s manual because it’s the portion of the machine that’s visible to the assembly language programmer, the compiler writer, and the application programmer. ...
