We tackle the problem of improving the SoC (System on a Chip) design flow in order to provide a modeling framework which allows exchange, reuse and integration of IP (Intellectual Property) models. In this paper, exploiting the MDA capabilities of defining modeling languages platform independent and reducible to platform dependent languages, we present a(More)
In this paper, we present a SoC design methodology joining the capabilities of UML and SystemC to operate at system-level. We present a UML 2.0 profile of the SystemC language exploiting the MDA capabilities of defining modeling languages, platform independent and reducible to platform dependent languages. The UML profile captures both the structural and(More)
This paper presents a prototype environment for HW/SW co--design of embedded systems based on the Unified Modeling Language (UML) and SystemC. The environment supports a model-driven SoC design methodology which provides a graphical high-level representation of hardware and software components, and allows either C/C++/SystemC code generation from models and(More)
In the embedded systems and SoC (system-on-chip) area, we defined a model-driven design methodology based on UML 2.0, UML profiles and SystemC. In this paper, we present the development process UPES (unified process for embedded systems) that we define to foster our methodology in a systematic and seamless manner according to the platform-based design(More)
This paper starts with a brief introduction to the UML 2.0 and application-specific UML customizations via profiles. After a discussion of UML design tools with focus on EDA support, we present a HW/SW co-design approach and demonstrate how HW architectures are described together with application SW in a unique UML based environment. Using a dedicated(More)
In this paper we present a UML 2.0 <i>profile</i> for the SystemC language, which is a consistent set of modeling constructs designed to lift both structural and behavioral features (including events and time features) of the SystemC language to UML level. The main target of this profile is to provide a means for software and hardware engineers to improve(More)
This article summarizes our effort, since 2004 up to the present time, for improving the current industrial Systems-on-Chip and Embedded Systems design by joining the capabilities of the unified modeling language (UML) and SystemC/C programming languages to operate at system-level. The proposed approach exploits the OMG model-driven architecture&#8212;a(More)
The paper presents the design and multi-parameter optimization of a networked embedded application for the health-care domain. Several hardware, software, and application parameters, such as clock frequency, sensor sampling rate, data packet rate, are tuned at design- and run-time according to application specifications and operating conditions to optimize(More)
The UML (Unified Modeling Language), with the enhancements in UML 2.0, is receiving interest by an increasing number of industrial and academic groups from the EDA, embedded software and hardware systems , who look at it and at its extension mechanisms as a practical and standard means to define family of languages targeted to specific application domains(More)
This paper describes a system design framework for SoC that allows to model together the functional application, the hardware architecture and the embedded software. It relies on a commercial CASE tool that provides a graphical design entry by the UML, we added code generation capabilities to produce an executable model based on SystemC and introduced a(More)
