Gecos
Keywords: Source-to-source compiler - Model-driven software engineering - Retargetable compilation
Scientific Description
The Gecos (Generic Compiler Suite) project is a source-to-source compiler infrastructure developed in the Cairn group since 2004. It was designed to enable fast prototyping of program analysis and transformation for hardware synthesis and retargetable compilation domains.
Gecos is 100% Java based and takes advantage of modern model driven software engineering practices. It uses the Eclipse Modeling Framework (EMF) as an underlying infrastructure and takes benefits of its features to make it easily extensible. Gecos is open-source and is hosted on the Inria gforge at http://gecos.gforge.inria.fr.
The Gecos infrastructure is still under very active development, and serves as a backbone infrastructure to projects of the group. Part of the framework is jointly developed with Colorado State University and between 2012 and 2015 it was used in the context of the FP7 ALMA European project. The Gecos infrastructure will also be used by the EMMTRIX start-up, a spin-off from the ALMA project which aims at commercializing the results of the project and in the context of the H2020 ARGO European project.
Functional Description
Gecos provides a program transformation toolbox facilitating parallelisation of applications for heterogeneous multiprocessor embedded platforms. This includes a polyhedral loop transformation toolbox, efficient SIMD code generation for fixed point arithmetic data-types, coarse-grain parallelization engine targeting the data-flow actor model, and a Matlab/Scilab front-end. In addition to targeting programmable processors, Gecos can regenerate optimized code for High Level Synthesis tools.
