WCET-Aware Parallelization of Model-Based Applications for Heterogeneous Parallel Systems

Deliverables

WCET-aware multi-core programming model (Rev. 1)

This report describes the programming model that is needed to develop applications that can be executed on the platforms.

State-of-the-art for WCET-aware optimization for heterogeneous multi-core architectures

This report will summarize the state-of-the-art for all important tasks covered within ARGO: model-based design, WCET analysis, heterogeneous multi-core architectures and toolchains to support a better programmability of said platforms.

Test case demonstration and evaluation report (first increment)

The report will present the evaluation results for the first iteration of the ARGO approach based on the results of the first iteration application test cases. The strengths and pitfalls of the tools and the methodology will be documented with regard to the first time user experience. The results will be used in WP3 and WP5 as user input.

WCET-aware multi-core programming model (Rev. 2)

This report describes the programming model that is needed to develop applications that can be executed on the platforms.

Specification of a WCET-aware abstract architecture description

This deliverable provides the specification of an abstract architecture description enabling both the platform-agnostic parallelization as well as code- and system-level WCET analysis.

Test case demonstration and evaluation report (second increment)

The report will introduce the results of the demonstration and the final evaluation of the ARGO approach. It will reflect the experience of the design and development of full functional test cases.

End-user guidelines for modelbased design (Rev. 2)

The report will provide end-user guidelines for application development in the model-based design environment. This includes the real-time constraints for WCET-analysis as well as the platform-specific constraints.

End-user guidelines for model-based design (Rev. 1)

The report will provide end-user guidelines for application development in the model-based design environment. This includes the real-time constraints for WCET-analysis as well as the platform-specific constraints.

Project website

The project website will be used for project promotion, public and scientific dissemination. It will be continuously updated during the project.

Final workshop

At the end of the project, a workshop will be organized demonstrating all the ARGO approach. The intended audience in scientific as well as non-scientific (e.g. press). The workshop might be part of a larger conference.

ATOMS module for frontend demonstrator directly downloadable from Scilab

Scilab users can download directly from the software modules for specific application domain. Scilab Enterprises will issue a module with the frontend tool at M24.
