Also interesting to note is that the x86 architecture provides a general flag, known as WP (Write Protect), inside CR0 that, when set, prevents privileged code from modifying any read-only page, regardless of w

Understanding what the instruction set can do and how the compiler makes use of those instructions can help developers write more efficient code. It can also help them understand the output of the compiler which can be useful for debugging. Arm is opening its instruction set architecture for Cort...

一些虚拟机支持基于Smalltalk,Java虚拟机,微软的公共语言运行时虚拟机所生成的字节码,他们的指令集体系将bytecode(字节码)从作为一般手段的代码路径翻译成本地的机器语言,并通过解译执行并不常用的代码路径,全美达以相同的方式开发了基于x86指令体系的VLIW处理器。
Computer instructions typically have three fields. These include an operation code, or opcode, field that identifies the operation to be performed, such as "add" data inmemoryto a specific register. They also have an address field, showing where registers and memory are located, and a mode fie...
