This paper presents a framework which automates the generation of DPR capable IP cores. The approach is based in an MDE methodology, which exploits two widely used standards for Systems-on-Chip specification, UML/MARTE and IP-XACT. The approach aims at generating IPs which incorporate different functionalities by using code templates. The templates correspond to IP-XACT components that represent VHDL modules to be implemented in the IP. The IP-XACT subsystem description is generated from the MARTE description, effectively diminishing the complexity of creating this kind of systems by increasing the level of abstraction. We present the MARTE modeling concepts and how these models are mapped to IP-XACT objects; the emphasis is given to the generation of IP cores that can be used in the Xilinx EDK environment, since we aim to develop a complete flow around their Dynamic Partial Reconfiguration design flow. A model for the DPR IP is presented and a case study for a simple IP is presented. The use of our MDE approach is introduced to demonstrate how the generation from MARTE to EDK systems is performed.

-In this paper we present framework for the deployment of hardware IPs at high-levels of abstraction. It is based in a modeldriven approach that aims at the automatic generation of Dynamic Partial Reconfiguration designs created in Xilinx Platform Studio (XPS). Contrary to previous approaches, we make use of the IP-XACT standard to facilitate the deployment of hardware IPs, their parameterization and subsequent integration. We propose an extension to the MARTE profile for IP deployment, and we introduce the necessary model transformations to obtain a highlevel representation from an IP-XACT component library. These models are then used to create a platform in MARTE that abstracts the technologic aspects of the chosen back-end. The soobtained UML platform is transformed in an IP-XACT design, which is exploited to generate the files used by XPS for system implementation. In this way, we promote IP reuse and deployment while remaining back-end independent, by using specific vendor extensions. Finally, we analyze the advantages of the proposed methodology by a case study in system integration.
