Esterel
Esterel is a synchronous programming language for the development of complex reactive systems. The imperative programming style of Esterel allows the simple expression of parallelism and preemption. As a consequence, it is well suited for control-dominated model designs. The development of the language started in the early 1980s, and was mainly carried out by a team of Ecole des Mines de Paris and INRIA led by Gérard Berry in France. Current compilers take Esterel programs and generate C code or hardware (RTL) implementations (VHDL or Verilog). The language is still under development, with several compilers out. The commercial development environment of Esterel is Esterel Studio. The company that commercialized itSynfora initiated a normalization process with the IEEE in April 2007 however the working group (P1778) dissolved March 2011. The reference manual is publicly available. A provisional version of Esterel has been implemented in Racket. The multiform notion of ti ...

SIGNAL Programming Language
SIGNAL is a programming language based on synchronized dataflow (flows + synchronization): a process is a set of equations on elementary flows describing both data and control. The SIGNAL formal model provides the capability to describe systems with several clocks (polychronous systems) as relational specifications. Relations are useful as partial specifications and as specifications of non-deterministic devices (for instance a non-deterministic bus) or external processes (for instance an unsafe car driver). Using SIGNAL allows one to specify an application, to design an architecture, to refine detailed components down to RTOS or hardware description. The SIGNAL model supports a design methodology which goes from specification to implementation, from abstraction to concretization, from synchrony to asynchrony. SIGNAL has been mainly developed in INRIA Espresso team since the 1980s, at the same time as similar programming languages, Esterel and Lustre. A brief history ...

Synchronous Programming Languages
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 computing, 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 ...

Gérard Berry
Gérard Philippe Berry (born 25 December 1948) is a French computer scientist, member of the French Academy of Sciences (Académie des sciences), French Academy of Technologies (Académie des technologies), and Academia Europaea. He was the Chief Scientist Officer of Esterel Technologies from 2000 to 2009. He held the 2007-2008 yearly Liliane Bettencourt chair of Technological Innovation at the Collège de France. He was Director of Research at INRIA Sophia-Antipolis and held the 2009-2010 yearly Informatics and Digital Sciences chair at the Collège de France. Berry's work, which spans over more than 30 years, brought important contributions to three main fields: * lambda calculus and functional programming * parallel and real-time programming languages * design automation for synchronous digital circuits Berry is known for the Esterel programming language.

French Institute For Research In Computer Science And Automation
The National Institute for Research in Digital Science and Technology (Inria) () is a French national research institution focusing on computer science and applied mathematics. It was created under the name French Institute for Research in Computer Science and Automation (IRIA) () in 1967 at Rocquencourt near Paris, part of Plan Calcul. Its first site was the historical premises of SHAPE (central command of NATO military forces), which is still used as Inria's main headquarters. In 1980, IRIA became INRIA. Since 2011, it has been styled ''Inria''. Inria is a Public Scientific and Technical Research Establishment (EPST) under the double supervision of the French Ministry of National Education, Advanced Instruction and Research and the Ministry of Economy, Finance and Industry. Administrative status Inria has nine research centers distributed across France (in Bordeaux, Grenoble- Inovallée, Lille, Lyon, Nancy, Paris- Rocquencourt, Rennes, Saclay, and Sophia Antipolis) an ...

Racket (programming Language)
Racket is a General-purpose programming language, general-purpose, multi-paradigm programming language. The Racket language is a modern dialect of Lisp (programming language), Lisp and a descendant of Scheme (programming language), Scheme. It is designed as a platform for programming language theory, programming language design and implementation. In addition to the core Racket language, ''Racket'' is also used to refer to the family of programming languages and set of tools supporting development on and with Racket. Racket is also used for script (computing), scripting, computer science education, and research. The Racket platform provides an implementation of the Racket language (including a runtime system, libraries, and compiler supporting several compilation modes: machine code, machine-independent, interpreted, and JIT) along with the DrRacket integrated development environment (IDE) written in Racket. Racket is used by the ProgramByDesign outreach program, which aims to tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Programming Model
In computing, a parallel programming model is an abstraction of parallel computer architecture, with which it is convenient to express algorithms and their composition in programs. The value of a programming model can be judged on its ''generality'': how well a range of different problems can be expressed for a variety of different architectures, and its ''performance'': how efficiently the compiled programs can execute. The implementation of a parallel programming model can take the form of a library invoked from a programming language, as an extension to an existing languages. Consensus around a particular programming model is important because it leads to different parallel computers being built with support for the model, thereby facilitating portability of software. In this sense, programming models are referred to as '' bridging'' between hardware and software.Leslie G. Valiant, "A bridging model for parallel computation", Communications of the ACM, Volume 33, Issue 8, Augu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erroneous Program
In the design of 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 def ...s, an erroneous program is one whose semantics are not well-defined, but where the language implementation is not obligated to signal an error either at compile or at execution time. For example, in Ada: :In addition to bounded errors, the language rules define certain kinds of errors as leading to erroneous execution. Like bounded errors, the implementation need not detect such errors either prior to or during run time. Unlike bounded errors, there is no language-specified bound on the possible effect of erroneous execution; the effect is in general not predictable.''Ada Reference Manual'' ISO/IEC 8652:1995(Epdf section 1.1.5. Defining a condition as "erroneous" means that the language implem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
