A low-level language is the right tool to develop applications for some embedded systems. Notwithstanding, a high-level language provides a proper environment to develop the programming tools. The target device is a system-onchip consisting of an array of processors with only local communication. Applications include typical streaming applications for digital signal processing. We describe the ...

The Unified Modeling Language (UML) is a language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system. UML supports the most typical software modeling problems; however, due to the diversity of software development domains, there may be occasions when the model requires elements or notations not provided by standard UML. This paper presents an...

The development of distributed applications is alleviated by tools that offer a suitable abstraction of the communication between two disjoint program parts. This abstraction is close to the typical means of exchanging information in an imperative programming language: a procedure call or a method invocation. These techniques are called middleware because they bridge the abstractions of the ope...

This paper presents a taxonomy of previous work on infrastructures, architectures and development environments for representing and processing Language Resources (LRs), corpora, and annotations. This classification is then used to derive a set of requirements for a Software Architecture for Language Engineering (SALE). The analysis shows that a SALE should address common problems and support ty...
