Combined Control Flow Dominated and Data Flow Dominated High-Level Synthesis

This paper presents the design of a Videophone CoderDecoder Motion Estimator using two High-Level Synthesis tools. Indeed, the combination of a Control Flow Dominated part (complex communication protocol) with a Data Flow Dominated part (high throughput computations) makes this circuit dicult to be synthesized by a single HLS tool. The combination of two HLS tools for the high-level design of this operator required the denition of a sophisticated design ow allowing mixed-level and multi-language simulations. When compared to design starting from RTL specications, HLS induces only a negligible area overhead of 5%, and provides gain in descriptionlength (divided by 5), design time and exibility.
