Assembly之instruction之Status register

JC Jump if carry setJHS  Jump if higher or same Syntax JC label JHS label Operation If C = 1: PC + 2 × offset −> PC If C = 0: execute following instruction Description The status register carry bit (C) is tested. If it is set, the 10-bit signed offse

JMP  Jump unconditionally Syntax   JMP  label Operation PC + 2 × offset −> PC Description The 10-bit signed offset contained in the instruction LSBs is added to the program counter. Status Bits Status bits are not affected. Hint: This one-word instru

A data processing system includes a plurality of transaction masters (4, 6, 8, 10) each with an associated local cache memory (12, 14, 16, 18) and coupled to coherent interconnect circuitry (20). Monitoring circuitry (24) within the coherent intercon

Byte and word issues 1 Appending “.b” to an instruction makes it a byte operation. A byte instruction with a register destination clears the high 8 bits of the register to 0. Thus, the following would clear the top byte of the register, leaving the l

写在前面 2012年写的,仅供参考 反汇编的目的 缺乏某些必要的说明资料的情况下, 想获得某些软件系统的源代码.设计思想及理念, 以便复制, 改造.移植和发展: 从源码上对软件的可靠性和安全性进行验证,对那些直接与CPU 相关的目标代码进行安全性分析: 涉及的主要内容 分析ARM处理器指令的特点,以及编译以后可执行的二进制文件代码的特征: 将二进制机器代码经过指令和数据分开模块的加工处理: 分解标识出指令代码和数据代码: 然后将指令代码反汇编并加工成易于阅读的汇编指令形式的文件: 下面给出个示例
