  2. Assembly language - Wikipedia

    en.wikipedia.org/wiki/Assembly_language

    In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]

  3. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    Machine code can easily be decoded back to its corresponding assembly language source code because assembly language forms a one-to-one mapping to machine code. [17] The assembly language decoding method is called disassembly. Machine code may be decoded back to its corresponding high-level language under two conditions: The first condition is ...

  4. x86 assembly language - Wikipedia

    en.wikipedia.org/wiki/X86_assembly_language

    x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.

  5. TEST (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/TEST_(x86_instruction)

    In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...

  6. Low-level programming language - Wikipedia

    en.wikipedia.org/wiki/Low-level_programming_language

    Assembly language has little semantics or formal specification, being only a mapping of human-readable symbols, including symbolic addresses, to opcodes, addresses, numeric constants, strings and so on. Typically, one machine instruction is represented as one line of assembly code, commonly called mnemonics. [8]

  7. INT (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/INT_(x86_instruction)

    INT is an assembly language instruction for x86 processors that generates a software interrupt. It takes the interrupt number formatted as a byte value. [1] When written in assembly language, the instruction is written like this: INT X. where X is the software interrupt that should be generated (0-255).

  8. List of programming languages by type - Wikipedia

    en.wikipedia.org/wiki/List_of_programming...

    Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings. Application control languages can be implemented this way, if the source code is input by the user. Languages with small interpreters are preferred.

  9. JMP (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/JMP_(x86_instruction)

    In the x86 assembly language, the JMP instruction performs an unconditional jump. Such an instruction transfers the flow of execution by changing the program counter.There are a number of different opcodes that perform a jump; depending on whether the processor is in real mode or protected mode, and an override instruction is used, the instructions may take 16-bit, 32-bit, or segment:offset ...
