Description

technical field

[0001] The invention relates to network technology, in particular to the realization technology of interconnection between a fourth-level system packet-level interface (SPI4) and a peripheral component expansion interface (PCI Express). Background technique

[0002] With the development of network technology, the application of high-speed signal transmission in network design is becoming more and more common. One of the currently used high-speed signal transmission interfaces is SPI4.

[0003] SPI4 is a data packet or cell transfer interface between physical layer devices and link layer devices, which can support data transfer rates up to 16Gb / s.

[0004] PCI Express is also a chip interconnect technology. As an interconnection bus of point-to-point serial architecture, it greatly improves the performance of bus interconnection and reduces the cost of the system.

[0005] However, there are also big differences between the above two interconnection technolo...
