Original Abstract Submitted

Instead of an arbitration over the link not considering bursts, a smart scheduler in a solid state drive (SSD) host interface is burst aware. The scheduler considers the type of transactions that are going to be sent over the interface. The scheduler sends the transactions in the most efficient way while maximizing the efficiency over the host DRAM. The schedulers may be calibrated from time to time on-the-fly to find the optimal configurations adapted to the current workload. The scheduler will organize the packets selected by the arbitration module so that the data transfers are sent in a burst of a predetermined sized to the host for optimum performance. For further optimization other packet types are sent in bursts as well.
