Synchronization Processor Synthesis for Latency Insensitive Systems
Résumé
In this paper we present our contribution in terms of synchronization processor to the SoC design methodology based on the theory of the latency insensitive systems (LIS) of Carloni et al.. This methodology 1) promotes pre-developed IPs intensive reuse, 2) segments inter-IPs in-terconnects with relay stations to break critical paths and 3) brings robustness to data stream irregularities to IPs by encapsulation into a synchronization wrapper. Our contribution consists in IP encapsulation into a new wrapper model containing a synchronization processor which speed and area are optimized and synthetizability guarantied. The main benefit of our approach is to pre-serve the local IP performances when encapsulating them. This approach is part of the GAUT project which targets design of intensive signal processing systems[1].
