![]() Unlike assembly language, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling, a much more complicated task than assembling. (Find our more about RISC – Reduced Instruction Set – and CISC – Complex instruction Set – processors) More complex architectures will result in a wider range of instructions making it easier to write assembly code. Basic computer architectures will result in a reduced number of instructions. This process is called “assembling” and is preformed by an assembler: a piece of software utility used to translate/assemble low-level code into binary code.īecause assembly depends on the machine code instructions, every assembler has its own assembly language which is designed for exactly one specific computer architecture.Īssembly language usually has one statement per machine instruction so there is the 1:1 relationship between a low-level instruction and a machine instruction. Little Man Computer Open in new tab/windowīecause assembly language use a relatively basic syntax and a limited number of mnemonics, the translation process to convert low level code into machine code (aka object code or binary code) is fairly straightforward. INP, OUT, STA, BRP, etc.) and is based on one memory addressing mode: direct addressing. LMC (Little Man Computer) is an example of basic assembly language used for educational purposes. ![]() Assembly languages also let you use labels in the code to point to specific memory locations or registers. Most assembly languages let you use different modes of addressing to specify the value (immediate addressing) or location/memory address of an operand. Many operations require one or more operands in order to form a complete instruction. Assembly language uses mnemonics to represent low-level machine instructions or opcodes. ![]() ![]() Each assembly language is specific to a particular computer architecture. Assembly language is a low-level programming language. ![]()
