Abstract：With the rapid development of technology，the increase in chip frequency has become a significant

trend that cannot be ignored in the industry. The increase in chip frequency directly drives the gradual increase in

data throughput of chip communication interfaces. In the field of transmission equipment，the communication speed between multiple chips in the controller has become a key bottleneck that restricts the further improvement of the overall performance of the equipment. In response to this issue，the design concept of "ping-pong" was introduced innovatively. This idea cleverly utilized the temporary caching mechanism between chips to achieve high-speed and high-throughput data exchange. The "ping-pong" design concept effectively avoided data errors caused by simultaneous reading and writing of the same address during high-speed communication by alternately using

different cache areas for data read and write operations，fundamentally ensuring the accuracy and reliability of data

transmission. After long-term on-site operation and monitoring，the device demonstrated stable performance and

efficient data processing capabilities，verifying the feasibility of the proposed solution.
