In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers machine code is "the binary representation of a computer program which is actually read and interpreted by the computer.
Assembly language. A program written in assembly language consists of a series of mnemonic processor instructions and meta-statements (known variously as declarative operations, directives, pseudo-instructions, pseudo-operations and pseudo-ops), comments and data.
Machine code. In computer science, an instruction set architecture ( ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [ 1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
Each "instruction" is a word that points to a function or an instruction sequence, possibly followed by a parameter. The threaded code interpreter either loops fetching instructions and calling the functions they point to, or fetches the first instruction and jumps to it, and every instruction sequence ends with a fetch and jump to the next ...
t. e. A computer program is a sequence or set [ a] of instructions in a programming language for a computer to execute. It is one component of software, which also includes documentation and other intangible components. [ 1] A computer program in its human-readable form is called source code.
Instructional design (ID), also known as instructional systems design and originally known as instructional systems development (ISD), is the practice of systematically designing, developing and delivering instructional materials and experiences, both digital and physical, in a consistent and reliable fashion toward an efficient, effective, appealing, engaging and inspiring acquisition of ...
Cryptographic (e.g. RDRAND, AES-NI) Discontinued (e.g. 3DNow!, MPX, XOP) v. t. e. The x86 instruction set refers to the set of instructions that x86 -compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.
Test-and-set. In computer science, the test-and-set instruction is an instruction used to write (set) 1 to a memory location and return its old value as a single atomic (i.e., non- interruptible) operation. The caller can then "test" the result to see if the state was changed by the call. If multiple processes may access the same memory ...
