汇编语言(assembly language/code):是一种低级别(low-level)的编程语言。与计算机执行的逻辑更加接近,与我们正常使用的语言差别很大,但是里面的符号依然可以被人大致识别。 机器语言(machine language/code):是可以被CPU直接识别并执行的语言或者代码。 本文将简单介绍这几种编程语言之间的差别。 机器语言(Machine Langu...
我们日常很多code语言都是 high-level programming Language 要翻译成汇编再翻译成二进制的机器语言; 4-4 Instruction Sets 每个机器都有一个自己的指令集; 4-5 MIPS Instruction Types MIPS的指令; 比如一个a = b+c 我们需要知道 b在哪 c在哪,并且相加之后的结果存储在哪; 同理 另一个例子 更复杂一点的自...
(in other words, to do the machine code equivalent of Applesoft BASIC'S POKE 1500,5), we would need to POKE the following bytes into memory: 169 5 141 220 5 and then ask the Apple's microprocessor to execute them. Not exactly clear, is it? That's where assembly language comes in....
Assembly is a low-level programming language in which there is a very strict correspondence between language instructions and architecture machine code instructions. Here are 1,989 public repositories matching this topic... Language:All Sort:Most stars ...

using the coding language and how a machine interprets the code instructions. Code is converted into executable actions using an assembler that converts input into recognizable instructions for the machine. Though prevalent in the early days of computing, many larger systems use higher-level ...

摘要:汇编语言 向屏幕输出文字 + 向屏幕输出需要向显示缓冲区写数据(在dosbox中在内存的其实位置是0b800h:0000h) + 输出的一个字符其实占用的是两个字节(一个字单位), 因为我们不仅要输出一个8位的ASCII, 还要输出该字符的属性, 包括高亮, 颜色, 底色等, 这些有另一个8位决定, 阅读全文 » Assembly...
To do this, we use directives: directions for the assembler to do something other than simply translate an assembly language instruction into its corresponding machine code. One useful directive is DCD, which inserts one or more 32-bit numerical values into the machine code output. (DCD cryptic...
Because the assembly code can be mixed inline with C or C++ statements, it can do tasks that are cumbersome or impossible in C or C++. The uses of inline assembly include: Writing functions in assembly language. Spot-optimizing speed-critical sections of code. Making direct hardware access ...
