Y-chart Application Programmer's Interface

What is YAPI

Abstract

YAPI is an application programmer's interface to write signal and stream processing applications as process networks. The communication between processes is based on Kahn Process Networks with blocking reads on theoretically unbounded fifos. The library contains a C++ run-time environment to execute applications on desktops and workstations.

History

YAPI has been developed at Philips Research. The Electronic Design and Tools department maintained and supported YAPI up to 2005. Currently, the project is hosted at SourceForge.net
