Assembly Language
Programming LanguageSee more on en.wikipedia.org · Text under CC-BY-SA licenseIn computer programming, assembly language, often abbreviated asm, is any low-level programming language in which there is a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Because assembly depends on the machine code instructions, ever…- Historical perspective
Assembly languages were not available at the time when the stored-program computer was introduced. Kathleen Booth "is credited with inventing assembly language" based on theoretical work she began in 1947, while working on the ARC2 at Birkbeck, University of London following … - Current usage
There have always been debates over the usefulness and performance of assembly language relative to high-level languages. Although assembly language has specific niche uses where it is important, there are other tools for optimization. As of July 2017, the TIOBE index of programm...
- An assembly language program is a series of statements, which are either assembly language instructions such as ADD and MOV, or statements called directives.An instruction tells the CPU what to do, while a directive (also called pseudo-instructions) gives instruction to the assembler. For example, ADD and MOV instructions are commands which the CPU runs, while ORG and EN…
- In addition to codes for machine instructions, assembly languages have extra directives for assembling blocks of data, and assigning address locations for instructions or code.They usually have a simple symbolic capability for defining values as symbolic expressions which are evaluated at assembly time, making it possible to write code that is easier to read and understa…
- An assembly language is the most basic programming language available for any processor. With assembly language, a programmer works only with operations that are implemented directly on the physical CPU.
- ARM Assembly Language Programming is a book I wrote back in 1987 describing the instruction set of the then current ARM architecture, which was ARM3. It also contained some tutorial information about machine code, assembly language, data structures and using the BBC BASIC assembler.The book is long out of print, and even I don't have any copies left, my las…
- Assembly language is also known as assembly code. The term is often also used synonymously with 2GL.
- 1. A macro assembler includes a macroinstruction facility so that (parameterized) assembly language text can be represented by a name, and that name can be used to insert the expanded text into other code. 2. A cross assembler (see also cross compiler) is an assembler that is run on a computer or operating system (the host system) of a different type from the system on which …
- A microprocessor is a mechanical calculator. It has a number of named registers, which are like holding pens for numbers. It receives instructions in the form of machine code, which is represented by a series of binary bits (1s and 0s). For example, here is a line of machine code:The first few bits (10110) are an instruction to copy a value into a register. The next three digits (000…
- This page is the portal to a web-based version of my 1987 book, ARM Assembly Language Programming (AALP). For this first release, I'm just making the original files and various conversions of the book available on this site, the most useful one probably being the HTML linked to above. (I generated the PDF from IE5.5's rendering of the HTML because NS6 didn't see…
- Basic elements
There is a large degree of diversity in the way the authors of assemblers categorize statements and in the nomenclature that they use. In particular, some describe anything other than a machine mnemonic or extended mnemonic as a pseudo-operation. A typical assembly language consi... - Macros
Many assemblers support predefined macros, and others support programmer-defined macros involving sequences of text lines in which variables and constants are embedded. The macro definition is most commonly a mixture of assembler statements, e.g., directives, symbolic machi…
- Assembler
An assembler program creates object code by translating combinations of mnemonics and syntax for operations and addressing modes into their numerical equivalents. This representation typically includes an operation code as well as other control bits and data. The assembler also c... - Assembly language
A program written in assembly language consists of a series of mnemonic processor instructions and meta-statements, comments and data. Assembly language instructions usually consist of an opcode mnemonic followed by a list of data, arguments or parameters. These are translated by...
- Assembly languages generally lack high-level conveniences such as variables and functions, and they are not portable between various families of processors. They have the same structures and set of commands as machine language, but allow a programmer to use names instead of numbers. This language is still useful for programmers when speed is necessary or when they n…
