Synchronous Programming Language
A synchronous programming language is a computer programming language optimized for programming reactive systems. Computer systems can be sorted in three main classes: # ''Transformational systems'' take some inputs, process them, deliver their outputs, and terminate their execution. A typical example is a compiler. # ''Interactive systems'' interact continuously with their environment, at their own speed. A typical example is the web. # ''Reactive systems'' interact continuously with their environment, at a speed imposed by the environment. A typical example is the automatic flight control system of modern airplanes. Reactive systems must therefore react to stimuli from the environment within strict time bounds. For this reason they are often also called real-time systems, and are found often in embedded systems. Synchronous programming, also called synchronous reactive programming (SRP), is a computer programming paradigm supported by synchronous programming languages. The pr ...

Computer Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Atom (programming Language)
Atom is a domain-specific language (DSL) in Haskell, for designing real-time embedded software. History Originally intended as a high-level hardware description language (HDL), Atom was created in early 2007 and released as free and open-source software (FOSS) of April of that year. Inspired by TRS and Bluespec, Atom compiled circuit descriptions, that were based on guarded atomic operations, or conditional term rewriting, into Verilog netlists for simulation and logic synthesis. As a hardware compiler, Atom's main objective is to maximize the number of operations, or rules, that can execute in a given clock cycle without violating the semantics of atomic operation. By employing the properties of conflict-free and sequentially composable rules, Atom reduced maximizing execution concurrency to a feedback arc set optimization of a rule-data dependency graph. This process was similar to James Hoe's original algorithm. When Atom's author switched careers in late 2007, from logic d ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose 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 Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. 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 most widely used programming langu ...

Concurrency (computer Science)
Concurrency refers to the ability of a system to execute multiple tasks through simultaneous execution or time-sharing (context switching), sharing resources and managing interactions. Concurrency improves responsiveness, throughput, and scalability in modern computing, including: * Operating systems and embedded systems * Distributed systems, parallel computing, and high-performance computing * Database systems, web applications, and cloud computing Related concepts Concurrency is a broader concept that encompasses several related ideas, including: * Parallelism (simultaneous execution on multiple processing units). Parallelism executes tasks independently on multiple CPU cores. Concurrency allows for multiple ''threads of control'' at the program level, which can use parallelism or time-slicing to perform these tasks. Programs may exhibit parallelism only, concurrency only, both parallelism and concurrency, neither. * Multi-threading and multi-processing (shared ...

Asynchronous Programming
Asynchrony, in computer programming, refers to the occurrence of events independent of the main program flow and ways to deal with such events. These may be "outside" events such as the arrival of signals, or actions instigated by a program that take place concurrently with program execution, without the program hanging to wait for results. Asynchronous input/output is an example of the latter case of asynchrony, and lets programs issue commands to storage or network devices that service these requests while the processor continues executing the program. Doing so provides a degree of concurrency. A common way for dealing with asynchrony in a programming interface is to provide subroutines that return a future or promise that represents the ongoing operation, and a synchronizing operation that blocks until the future or promise is completed. Some programming languages, such as Cilk, have special syntax for expressing an asynchronous procedure call. Examples of asynchrony incl ...

Secure Operations Language
The Secure Operations Language (SOL) was developed jointly by the United States Naval Research Laboratory and Utah State University in the United States. SOL is a domain-specific synchronous programming language for developing distributed applications and is based on software engineering principles developed in the Software Cost Reduction project at the Naval Research Laboratory in the late 1970s and early 1980s. SOL is intended to be a domain-specific language A domain-specific language (DSL) is a computer language specialized to a particular application domain. This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains. There are a wide variety of DSLs, ranging ... for developing service-based systems. Concurrently, a domain-specific extension of Java (SOLj) is being developed (FTDCS 2007) Application domains include sensor networks, defense and space systems, healthcare delivery, power control, etc. The investigators of the project ...

Blech (programming Language)
A ''blech'' (from the Yiddish word בלעך () meaning "tin" or "sheet metal", alternatively from Middle High German or Standard German "Blech", meaning tin or sheet metal) is a metal sheet used by many observant Jews to cover stovetop burners (and for some, the cooker's knobs and dials) on Shabbos (the Jewish Sabbath), as part of the precautions taken to avoid violating the halachic prohibition against cooking on the Sabbath. Common use Rabbi Fishel Jacobs' ''The Blech Book—The Complete & Illustrated Guide To Shabbos Hotplates'' gives the following guidelines: * The food (including water) intended for Shabbos use should be completely cooked. * The stove's gas flames or electric coils are turned on. The ''blech'' is placed over these. Alternatively, the Shabbos hot plate, which needs no ''blech'' (when it is the type which has no knobs to adjust the heat level) is plugged in. * The pot is placed on the ''blech''. It is permissible to place another pot on this one. * The pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
