Abstract:

In modern embedded systems, the C2RTL (high-level synthesis) technology helps the designer to greatly reduce time-to-market, while satisfying the performance and cost constraints. To attack the performance challenges in complex designs, we propose a FIFO-connected hierarchical approach to replace the traditional flatten one in stream applications. Furthermore, we develop an analytical algorithm to find the optimal FIFO capacity to connect multiple modules efficiently. Finally, we prove the advantages of the proposed method and the feasibility of our algorithm in seven real applications. Experimental results show that the hierarchical approach can have an up to 10.43 times speedup compared to the flatten design, while our analytical FIFO sizing algorithm shrinks design time from hours to seconds with the same accuracy compared to the simulation based approach.
