AI Technical Summary

Technical Problem

In existing technologies, the high bandwidth capability of the 1188B bus cannot be fully utilized due to the limitations of the 1GbE physical layer, resulting in unmet needs for high-speed data acquisition and real-time control, thus wasting bandwidth.

Method used

Seamless conversion between PCIe and 1188B protocols is achieved through a protocol conversion chip. Combined with programmable logic devices, cache memory, and non-volatile memory, storage resources are dynamically allocated to ensure fast response of high-priority data and reliable storage of low-priority data.

Benefits of technology

It breaks through the 1Gbps bandwidth limit, meets the needs of high-speed data acquisition and real-time control, improves data transmission efficiency and flexibility, and ensures rapid response of critical data and reliable storage of non-critical data.

Abstract

This utility model discloses an 1188B communication module and communication system, relating to the field of communication technology. The 1188B communication module includes a protocol conversion chip and a connector. The protocol conversion chip is connected to the connector via a PCIe interface and an 1188B interface. The protocol conversion chip is used to: receive Transaction Layer (TLP) data packets from the connector via the PCIe interface; convert the TLP data packets into 1188B link layer data frames; and send the 1188B link layer data frames to the connector via the 1188B interface. Therefore, the 1188B communication module provided in this application avoids the conversion scheme using 1000 Mbps Ethernet as the conversion medium, achieving seamless conversion between the PCIe protocol and the 1188B protocol through the protocol conversion chip, thereby breaking through the 1Gbps bandwidth limitation and meeting the needs of high-speed data acquisition and real-time control.
