| Abstract(in English) | Ethernet-based I/O bus is extension technology of an I/O bus to an Ethernet by encapsulating a PCI Express (PCIe) packet of an I/O bus to an Ethernet frame. In such systems, because the size of a PCIe packet is generally small, the encapsulation overhead of an individual PCIe packet to an Ethernet frame decreases PCIe bandwidth. We propose a method to enhance the PCIe bandwidth by aggregating multiple PCIe packets and encapsulate them into a single Ethernet frame. The proposed method aggregates packets that reside in a queue at the time of encapsulation, which provides low-latency PCIe bandwidth enhancement with reduced circuit footprint and no parameter configuration. The implemented prototype using an FPGA showed I/O performance was enhanced by up to 41%. |
