Problems solved by technology

[0006] However, in some design occasions, due to specific considerations, we also need to interconnect SPI4 devices with PCI Express devices, especially to achieve high-speed data transmission and reception between the two devices. However, since the SPI4 interface only involves the physical layer And the content of the data link layer, and the PCI Express interface has one more processing layer protocol than the SPI4 interface, so so far, there is no technical solution that can solve the problem of the interconnection between the SPI4 interface and the PCI Express interface

Abstract

This invention discloses a system for realizing interconnection between devices of SP14 and PCI Express including: devices SP14 and PCI Express and converting unit between them used in analyzing the received data to be converted to the process layer content of them and sent to the devices of SP14 or PCI, said system also includes an interruption unit and a CPU interface unit, in which, the conversion unit can analyze the data sent by them and convert the format so that the converted format is in conformity with that of them so as to solve the interconnection between them. A method for realizing the inter-connection between devices of them is provided.

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...
