Abstract

The invention provides a processing method of SPI4 interface data packet, which comprises the following steps of: acquiring midpoint data of a data valid window through carrying out delayed transaction on interface data; carrying out protocol conversion on the delayed interface data and removing control words in the conversed interface data; and carrying out alignment operation on the interface data after being removed the control words and receiving the interface data. By using the invention, a common interface of 10Gbps WAN, LAN, MAN and SAN can be realized, the design of an interface protocol is easier for engineering realization, pin number and power consumption are reduced and the completeness of a signal is enhanced.

Description

Technical field

[0001] The present invention relates to the field of communications, and in particular, to a processing method of SPI4 interface data packets. Background technique

[0002] SPI4.2 (System Packet Exchange Interface, Level 4) is a new system-level interface standard, according to which designers can develop flexible and upgradeable systems for centralized data and communication facilities. The SPI4 interface supports multiple protocols to transmit at different high rates. These protocols include information packets (POS frames) on SONET / SDH, OC-192, Ethernet, Fast Ethernet, Mbit Ethernet, 10 Mbit Ethernet Network and 10 Mbit Fibre Channel SAN, etc.

[0003] At present, the SPI4 interface is generally implemented through a dedicated ASIC or an expensive IP core, which is subject to greater constraints, higher costs, and is not compatible with network protocols such as 10Gbps WAN, LAN, MAN, and SAN. Summary of the invention

[0004] Considering the problems of high cos...
