2001 Proceedings of the ninth international symposium on Hardware/software codesign - CODES '01  
In this paper, we present a proposal for a UML profile called 'Embedded UML'.  ...  Finally, it provides an approach which supports the development of automated analysis, simulation, synthesis and code generation tool capabilities which can be provided for design usage even while the  ...  code generation.  ...

Shallow Embedding of Type Theory is Morally Correct [article]

Ambrus Kaposi, András Kovács, Nicolai Kraus
2019 arXiv   pre-print
First, we prove that shallow embedding is injective up to definitional equality, by modelling the embedding as a syntactic translation targeting the metatheory.  ...  There are multiple ways to formalise the metatheory of type theory.  ...  Compared to a previous formalisation using a deep embedding [3] , it is significantly shorter (322 vs. 1682 lines of code -we only counted the lines of code for the substitution calculus, Π and the universe  ...

Yet Another Deep Embedding of B:Extending de Bruijn Notations [article]

Eric Jaeger
2009 arXiv   pre-print
We present Bicoq3, a deep embedding of the B system in Coq, focusing on the technical aspects of the development.  ...  The main subjects discussed are related to the representation of sets and maps, the use of induction principles, and the introduction of a new de Bruijn notation providing solutions to various problems  ...  On the contrary, a deep embedding is better intuitively described as the development of a virtual machine: the syntax and the semantic of the guest logic are formalised as datatypes of the host logic.  ...

Certifying Machine Code Safety: Shallow Versus Deep Embedding [chapter]

Martin Wildmoser, Tobias Nipkow
2004 Lecture Notes in Computer Science  
In a shallow embedding logical formulas are written as HOL predicates, whereas a deep embedding models formulas as a datatype.  ...  Such a logic can be realised in Isabelle/HOL either as shallow or deep embedding.  ...  Using this mechanism we are able to generate an executable VCG from the definitions in Isabelle. Deep Embedding Syntax In a deep embedding we represent logical formulas as a datatype.  ...

Color2Embed: Fast Exemplar-Based Image Colorization using Color Embeddings [article]

Hengyuan Zhao, Wenhao Wu, Yihao Liu, Dongliang He
2021 arXiv   pre-print
In this paper, we present a fast exemplar-based image colorization approach using color embeddings named Color2Embed.  ...  Second, in order to reduce the process time, our method explicitly extracts the color embeddings and exploits a progressive style feature Transformation network, which injects the color embeddings into  ...  The proposed method consists of three main modules: color embeddings generation network, content embeddings generation network and Progressive Feature Formalisation Network (PFFN).  ...

The algebra of connectors

Simon Bliudze, Joseph Sifakis
2007 Proceedings of the 7th ACM & IEEE international conference on Embedded software - EMSOFT '07  
We provide a number of properties of AC(P ) used to symbolically simplify and handle connectors.  ...  We provide an algebraic formalisation of connectors in BIP. These are used to structure interactions in a componentbased system. A connector relates a set of typed ports.  ...  The Engine drives the execution of (the C++ code generated from) a BIP program.  ...

Formal Verification of Spacecraft Control Programs

Georgy Lukyanov, Andrey Mokhov, Jakob Lechner
2020 ACM Transactions on Embedded Computing Systems  
This paper presents a verification approach designed to help spacecraft engineers reduce the effort required for formal verification of low-level control programs executed on custom hardware.  ...  We present REDFIN, a processing core used in space missions, and its formal semantics expressed using the proposed metalanguage for state transformers, followed by examples of verification of simple control  ...  [12] formalised a subset of the x86 architecture in Coq, using monads for instruction execution semantics, and do-notation for assembly language embedding.  ...

Semantic Embedding of Petri Nets into Event-B [article]

Christian Attiogbe
2005 arXiv   pre-print
The static structure of a Petri-net is captured within a B abstract system through a graph structure.  ...  We present an embedding of Petri nets into B abstract systems. The embedding is achieved by translating both the static structure (modelling aspect) and the evolution semantics of Petri nets.  ...  There are two main embedding techniques: shallow embedding and semantic embedding (also called deep embedding).  ...

Beating the Productivity Checker Using Embedded Languages

Nils Anders Danielsson
2010 Electronic Proceedings in Theoretical Computer Science  
This paper gives a method for turning a productive program into a guarded program.  ...  The method amounts to defining a problem-specific language as a data type, writing the program in the problem-specific language, and writing a guarded interpreter for this language.  ...  = Tree (El a) El (stream a) = Stream (El a) El (a ⊗ b) = El a × El b El A = A The type U defines codes for elements of the universe, and El interprets these codes.  ...

Real-time Java API specifications for high coverage test generation

Wolfgang Ahrendt, Wojciech Mostowski, Gabriele Paganelli
2012 Proceedings of the 10th International Workshop on Java Technologies for Real-time and Embedded Systems - JTRES '12  
Even if there is a rationale behind this particular inconsistency, it demonstrates the effectiveness of our method on production code.  ...  This is achieved by basing the test generation on formal verification techniques, namely the KeY system for Java source code verification.  ...  A contract can be viewed as a formalised natural description of the method behaviour from the API documentation.  ...

Tool Support for Holistic Modelling of Distributed Embedded Systems in Creol

Marcel Kyas
2009 Electronical Notes in Theoretical Computer Science  
A holistic approach to modelling embedded systems is advocated: Many aspects of a system should be analysed in isolation to keep the task manageable, but they often influence each other during integration  ...  We focus on sensor networks, which are distributed system that consists of many embedded devices with tight constraints on computational power, energy availability, and timeliness.  ...  This is akin to a deep embedding into a theorem prover [28] , with similar advantages and disadvantages.  ...
