Platform-based design for digital signal processing systems: a case study of MPEG-2/JPEG2000 encoder

A SOC integration platform provides a multi-application system backbone for various application families. With minor effort, multiple designs in the same domain can be reached by reusing IP cores. However, there are several steps in SOC conception that can cause the design to fail. In addition of platforms, SOC designers need methodologies and formal models for success. One of the most important problems is the IP core integration. Successful integration of IP/VC blocks indeed requires a set of views that provides the ad hoc information for each IP block through the SOC design flow. This paper describes some key points of our IP integration methodology that exploits both IP designer and SOC integrator constraints. As an illustration, we present an example of a quantizer core reused from an MPEG design into a JPEG2000 encoder both implemented on the same SOC platform.
