Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work.
In computing, a compiler is a computer program that translates computer code written in one programming language into another language. The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language to create an executable program.
An integrated development environment (IDE) is a software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use. In 2009, it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.
pSOS is a real-time operating system (RTOS), created in about 1982 by Alfred Chao, and developed and marketed for the first part of its life by his company Software Components Group (SCG). In the 1980s, pSOS rapidly became the RTOS of choice for all embedded systems based on the Motorola 68000 series family architecture, because it was written in 68000 assembly language and was highly optimised from the start. It was also modularised, with early support for OS-aware debugging, plug-in device drivers, Internet protocol suite (TCP/IP) stacks, language libraries, and disk subsystems. Later came source code level debugging, multiprocessing support, and further computer networking extensions.
SPARK is a formally defined computer programming language based on the Ada programming language, intended for the development of high integrity software used in systems where predictable and highly reliable operation is essential. It facilitates the development of applications that demand safety, security, or business integrity.
Free and Open source Software Developers' European Meeting (FOSDEM) is a non-commercial, volunteer-organized European event centered on free and open-source software development. It is aimed at developers and anyone interested in the free and open-source software movement. It aims to enable developers to meet and to promote the awareness and use of free and open-source software.
Green Hills Software is a privately owned company that builds operating systems and programming tools for embedded systems. The firm was founded in 1982 by Dan O'Dowd and Carl Rosenberg. Its world headquarters are in Santa Barbara, California.
Software prototyping is the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.
A computer program is said to be portable if there is very low effort required to make it run on different platforms. The pre-requirement for portability is the generalized abstraction between the application logic and system interfaces. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction.
Rational Rhapsody, a modeling environment based on UML, is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software. Rational Rhapsody uses graphical models to generate software applications in various languages including C, C++, Ada, Java and C#.
DDC-I, Inc. is a privately held company providing software development of real-time operating systems, software development tools, and software services for safety-critical embedded applications, headquartered in Phoenix, Arizona. It was first created in 1985 as the Danish firm DDC International A/S, a commercial outgrowth of Dansk Datamatik Center, a Danish software research and development organization of the 1980s. The American subsidiary was created in 1986. For many years, the firm specialized in language compilers for the programming language Ada.
Approov (formerly CriticalBlue) is a Scottish software company based in Edinburgh that is primarily active in two areas of technology: anti-botnet and automated threat prevention for mobile businesses, and software optimization tools and services for Android and Linux platforms.
Advanced Computer Techniques (ACT) was a computer software company most active from the early 1960s through the early 1990s that made software products, especially language compilers and related tools. It also engaged in information technology consulting, hosted service bureaus, and provided applications and services for behavioral health providers. ACT had two subsidiaries of note, InterACT and Creative Socio-Medics.
Understand is a customizable integrated development environment (IDE) that enables static code analysis through an array of visuals, documentation, and metric tools. It was built to help software developers comprehend, maintain, and document their source code. It enables code comprehension by providing flow charts of relationships and building a dictionary of variables and procedures from a provided source code.
Tartan Laboratories, Inc., later renamed Tartan, Inc., was an American software company founded in 1981 and based in Pittsburgh, Pennsylvania, that specialized in programming language compilers, especially for the language Ada. It was based on work initially done at Carnegie Mellon University and gradually shifted from a focus on research and contract work to being more product-oriented. It was sold to Texas Instruments in 1996. Part of it was later acquired by DDC-I in 1998.
TeleSoft, Inc. was an American software development company founded in 1981 and based in San Diego, California, that specialized in development tools for the Ada programming language.
TLD Systems, Ltd. was an American software company active in the 1980s and 1990s and based in Torrance, California, that specialized in language compilers for the JOVIAL and Ada programming languages that were targeted to embedded systems.
