ObjecTime Developer
ObjecTime Developer (or ObjecTime or OTD, for short) is a software automation tool designed to meet the development needs of real-time software development teams. The tool was created by ObjecTime Limited of Kanata, Ontario, and was aimed at aiding software developers in building applications using Real-Time Object-Oriented Modeling Real-Time Object-Oriented Modeling (ROOM) is a domain-specific language. ROOM was developed in the early 1990s for modeling Real-time systems. The initial focus was on telecommunications, even though ROOM can be applied to any event-driven real-tim ... (ROOM) for real-time, graphical design models. ObjecTime, using the design models, will then generate production-quality applications for real-time operating systems, using the C and C++ programming languages. An important aspect of the development process using OTD was the capability to visually see the execution of the generated software as animation of the design models. This was true both for the s ...

Software Automation
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. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to specific kinds of projects, based on various technical, organizational, project, and team considerations. Software development activities Identification of need The sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanata, Ontario
Kanata (, ) is a suburb of Ottawa, Ontario, Canada. It is located about west of the city's downtown core. As of 2021, Kanata had an urban population of 137,118. Before it was amalgamated into Ottawa in 2001, it was one of the fastest-growing cities in Canada and the fastest-growing community in Eastern Ontario. Located just to the west of the National Capital Commission Greenbelt, it is one of the largest of several communities that surround central Ottawa. History The area that is today Kanata was originally part of the March Township, and was first settled by Europeans in the early 19th century. One site dating from this era is Pinhey's Point. It remained mainly agricultural until the 1960s when it became the site of heavy development. Modern Kanata is largely the creation of Bill Teron, a developer and urban planner who purchased over of rural land and set about building a model community. Unlike other suburbs, Kanata was designed to have a mix of densities and comme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-Time Object-Oriented Modeling
Real-Time Object-Oriented Modeling (ROOM) is a domain-specific language. ROOM was developed in the early 1990s for modeling Real-time systems. The initial focus was on telecommunications, even though ROOM can be applied to any event-driven real-time system. ROOM was supported by ObjecTime Developer (commercial) and is now implemented by the official Eclipse project eTrice When UML2 was defined (version 2 of UML with real time extensions), many elements of ROOM were adopted. Concepts and Key Notions of ROOM ROOM is a modeling language for the definition of software systems. It allows the complete code generation for the whole system from the model. ROOM comes with a textual as well as with a graphical notation. Typically the generated code is accompanied with manually written code, e.g. for graphical user interfaces (GUI). The code is compiled and linked against a runtime library which provides base classes and basic services (e.g. messaging). ROOM describes a software syste ...

Real-time Operating System
A real-time operating system (RTOS) is an operating system (OS) for real-time applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task prioritization in a multitasking or multiprogramming environment. Processing time requirements need to be fully understood and bound rather than just kept as a minimum. All processing must occur within the defined constraints. Real-time operating systems are event-driven and preemptive, meaning the OS is capable of monitoring the relevant priority of competing tasks, and make changes to the task priority. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts. Characteristics A key characteristic of an RTOS is the level of its consistency concerning the amount of time it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Unified Modeling Language
The Unified Modeling Language (UML) is a general-purpose, developmental modeling language in the field of software engineering that is intended to provide a standard way to visualize the design of a system. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. In 1997, UML was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) as an approved ISO standard. Since then the standard has been periodically revised to cover the latest revision of UML. In software engineering, most practitioners do not use UML, but instead produce informal hand drawn diagrams; these diagrams, however, often include elements from UML. History Before UML 1 ...

Rational Rose RealTime
Rational Machines is an enterprise founded by Paul Levy and Mike Devlin in 1981 to provide tools to expand the use of modern software engineering practices, particularly explicit modular architecture and iterative development. It changed its name in 1994 to Rational Software, and was sold for US$2.1 billion (equivalent to current US$) to IBM on February 20, 2003.
