Implementing Modal Software in Data Flow for Heterogeneous Architectures

This paper explores the implementation of modal software within data flow systems for heterogeneous architectures. Authors James Steed, Kerry Barnes, and William Lundgren discuss how modal software can segment data streams into manageable parts, enhancing processing capabilities. The Gedae programming tool is highlighted for its ability to effectively utilize Power-PC boards and FPGAs via the Gedae-RTL language extension. The study details methods such as segmentation, reset, and end-of-segment processing, showcasing how Gedae enables a complete modal software system across diverse hardware configurations.
