In computing, object code or object module is the product of an assembler or compiler. [1] In a general sense object code is a sequence of statements or instructions in a computer language, [2] usually a machine code language (i.e., binary) or an intermediate language such as register transfer language (RTL). The term indicates that the code is ...
p-code machine. In computer programming, a p-code machine ( portable code machine [1]) is a virtual machine designed to execute p-code (the assembly language or machine code of a hypothetical central processing unit (CPU)). This term is applied both generically to all such machines (such as the Java virtual machine (JVM) and MATLAB pre-compiled ...
This approach provides a relatively straightforward method of ensuring software compatibility between different products within a processor family. Some hardware vendors, notably IBM/Lenovo, use the term microcode interchangeably with firmware. In this context, all code within a device is termed microcode, whether it is microcode or machine code.
Porting. In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library ).
List of Enigma machine simulators lists software implementations of the Enigma machine, a rotor cypher device that was invented by German engineer Arthur Scherbius at the end of World War I. [1] and used in the early- to mid-20th century to protect commercial, [2] diplomatic, and military communication.
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.
Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations.
Embedded software. Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems. It is typically specialized for the particular hardware that it runs on and has time and memory constraints. [1] This term is sometimes used interchangeably with ...
