Embodiment Construction
[0035] The present application provides a computing system, a server and a signal transmission method. The computing system may include a plurality of chips. For the convenience of description, here only the computing system includes two chips, namely the first chip and the second chip, as an example. Be explained.
[0036] see Figure 1A , the computing system 10 includes a first chip 100 , a first transceiver 200 , a second chip 300 and a second transceiver 400 . The first chip 100 is connected to the first transceiver 200, signal transmission can be performed between the first chip 100 and the first transceiver 200, the second chip 300 is connected to the second transceiver 400, the second chip 300 and the second transceiver Signal transmission is possible between 400. It should be noted that the signal here generally refers to an electrical signal loaded with data. The electrical signal can be a parallel signal or a serial signal. In the embodiment of the present applica...

The invention discloses a calculation system, a server and a signal transmission method, which are used for improving data transmission speed and data volume between chips. In the application, the calculation system comprises a first chip, a first transceiver, a second chip and a second transceiver, the first transceiver is connected with the first chip, and the second transceiver is connected with the second chip; the first chip transmits a parallel signal. The first transceiver receives the parallel signal, converts the parallel signal into an optical signal, and sends the optical signal to the second transceiver. The second transceiver receives the optical signal, converts the optical signal into a parallel signal, and transmits the parallel signal to the second chip; the second chip may then receive the parallel signal. Data interaction between the first chip and the second chip is based on the optical signal. Compared with electric signals, optical signals are high in anti-interference performance, high in transmission speed, better in data integrity and higher in data transmission efficiency. The optical signal can load more data, so that the data volume of data transmission between the chips is increased.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a computing system, a server and a signal transmission method. Background technique [0002] With the rapid development of artificial intelligence and big data, in order to meet the needs of computing diversification, in addition to the central processing unit (central processing unit, CPU), the computing system will also introduce other hardware, such as graphics processing unit (graphics processing unit). , GPU), application specific integrated circuit (ASIC), programmable gate array (field programmable gate array, FPGA) and other accelerators (accelerator, ACC), these newly introduced hardware can cooperate with the CPU to achieve a variety of different calculations Task. Based on this, a new type of computing system—heterogeneous computing system is formed. [0003] The so-called heterogeneous computing system means that each hardware in the system, such...
