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.
In a simple central processing unit (CPU), the PC is a digital counter (which is the origin of the term "program counter") that may be one of several hardware registers. The instruction cycle [ 7] begins with a fetch, in which the CPU places the value of the PC on the address bus to send it to the memory. The memory responds by sending the ...
MSVC. v. t. e. Tracing just-in-time compilation is a technique used by virtual machines to optimize the execution of a program at runtime. This is done by recording a linear sequence of frequently executed operations, compiling them to native machine code and executing them.
e. In software engineering, profiling ("program profiling", "software profiling") is a form of dynamic program analysis that measures, for example, the space (memory) or time complexity of a program, the usage of particular instructions, or the frequency and duration of function calls. Most commonly, profiling information serves to aid program ...
Memory ordering is the order of accesses to computer memory by a CPU. Memory ordering depends on both the order of the instructions generated by the compiler at compile time and the execution order of the CPU at runtime. [1] [2] However, memory order is of little concern outside of multithreading and memory-mapped I/O, because if the compiler ...
Program execution. In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming ...
Control flow. v. t. e. In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
v. t. e. 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.
