520 %\section{Conclusion}
521 % \begin{frame}{Flow control}
523 % \item DirectAck is not scalable, but good for very small \acp{NoC}.\onslide<2->
524 % \item Single register is slower, but usable for any size of \ac{NoC}.\onslide<3->
525 % \item Double register requires twice as much area, but is fast and usable for any size of \ac{NoC}.\onslide<4->
526 % \item Windowed transmission requires very much buffer area in the tiles, and is therefore not recommended.\onslide<5->
528 % Scalable flow control always requires two buffers or two clock cycles.
530 % \begin{frame}{Choosing a NoC}
532 % \item Best Effort (BE) traffic:
534 % \item Much BE traffic: use Packet Switched.\onslide<2->
535 % \item Some control BE traffic: use SAnet with ring network.\onslide<3->
536 % \item No BE traffic: use SAnet with CSDCnet.\onslide<4->
537 % \item Some BE traffic can also be routed efficiently using circuits in the circuit switched network, bursts for example.\onslide<5->
538 % \item CSDCnet does not support connections initiated from the tiles.\onslide<6->
540 % \item Guaranteed Service (GS) traffic:
542 % \item High bandwidth streams: use circuit switched;
544 % \item Circuit switched has 4 outputs per port.
545 % \item Circuit switched can be clocked at 1GHz.\onslide<7->
547 % \item Low bandwidth streams: use packet switched;
549 % \item Streams can be multiplexed.
