Referring to fig. 1, fig. 1 is a flowchart of a wired communication method according to an embodiment of the present invention, where the method can be applied to a management center in a system shown in fig. 2 or fig. 3. The method comprises the following steps:
s101, acquiring connection information of a link corresponding to a transceiver newly inserted into the system, and configuring corresponding preset communication parameters for the link according to the connection information.
Referring to fig. 2 and 3, the transceiver can be inserted into the system via the IC card, wherein the communication interface is an interface circuit for the microcomputer system to directly perform digital communication with other systems. Each transceiver includes a transmitter (tx in fig. 2) and a receiver (rx in fig. 2).
Specifically, as shown in fig. 2, the system has N expandable ICs, each IC also has N high-speed transceivers (corresponding to links), and the communication interface between each IC and the management center may be a socket PCIe interface. That is, the transceiver can be plugged into or unplugged from the system by plugging it into or out of the IC card.
As shown in fig. 3, the IC card may be a pluggable card, and a corresponding transceiver is fixed on the IC card, so that the transceiver on the IC card is also plugged into the system by plugging the IC card.
Each transceiver may be connected to another transceiver through a connection medium, which may be a chip-to-chip, backplane, chip-to-module, chip card, or fiber card. I.e. transceiver + connection medium + physical structure of the transceiver, i.e. the corresponding link.
Specifically, the nth IC card in the system detects that the nth transceiver is inserted into the system, and the IC card informs the management center of the establishment of the new link through PCIe MSI interrupt (PCIe interrupt). Of course, the management center may also find a new transceiver inserted into the system by polling to read the IC information.
After finding out the newly inserted transceiver, the connection information of the link corresponding to the newly inserted transceiver of the system can be obtained, and the corresponding preset communication parameters are configured for the link according to the connection information.
Specifically, in an embodiment of the present application, the step S101 of obtaining connection information of a link corresponding to a transceiver newly inserted into the system includes:
step one, acquiring a connection state, a signal type and a connection medium of a link after detecting a transceiver newly inserted into a system;
and step two, determining the connection state, the signal type and the connection medium as connection information.
For convenience of description, the above two steps will be described in combination.
The nth IC can access (e.g., PCIe access) the nth IC to confirm the status of the new link (whether connection is successful, whether plug-in is locked) and the type of signal (what type of signal is transmitted, e.g., NRZ (Not Return to Zero) or PAM4 (Phase Amplitude Modulation4, i.e., 4-state signal)), connect to the medium, configure the corresponding preset equalization parameters stored in the non-volatile memory of the nth IC by default, establish the link, confirm the status of the transceiver of the other party through the new link via the network auto-negotiation protocol, confirm whether the link is established, and confirm the speed of the current link as single duplex information.
How to obtain the connection information and how to configure the corresponding preset communication parameters according to the connection information may be performed by referring to the existing manner of configuring fixed parameters for the link, which is not described in detail herein.
S102, after transmission power consumption of the optical module and the optical fiber jumper corresponding to the link is configured, the temperature and the power consumption of the link are monitored.
After the link is established, the system can configure the transmission power consumption of an AOC (Active Optical Cable, i.e., an Active Optical Cable Optical module and an Optical fiber jumper) specifically according to the application scenario of the link, and perform temperature and power consumption monitoring.
Specifically, after the newly given relevant parameter setting is configured, the temperature and the power consumption are monitored.
S103, under the condition of continuously adjusting communication parameters, carrying out pseudo-random code detection on the link to obtain the error rates under different communication parameters.
In order to select the most suitable communication parameter considering that the pre-configured communication parameter may not be the best parameter of the current link, in the present application, the communication parameter is continuously adjusted based on the pre-configured communication parameter, and the pseudo random code detection is performed on the link, so as to obtain the error rates under different communication parameters.
In an embodiment of the present application, the performing, in step S103, pseudo random code detection on the link under the condition of continuously adjusting the communication parameters to obtain the error rates under different communication parameters includes:
step one, configuring a channel buffer of a transceiver to close an internal loop;
and secondly, setting a search interval of each communication parameter under the reference of the preset parameters of link training and performing pseudo-random detection on the link to obtain the error rates under different communication parameters.
Specifically, under the reference of preset parameters of link tuning, a search interval of equalization parameters and/or pre-emphasis parameters is set, and pseudo-random detection is performed on the link to obtain error rates under different equalization parameters and/or pre-emphasis parameters.
For convenience of description, the above two steps will be described in combination.
The transceiver channel buffer corresponding to the nth IC is set to close the internal loop and perform external link training, as shown in fig. 2, the transceiver 1 performs receiving end and transmitting end interconnection with the transceiver 2 through a connection medium. The link tuning default parameter may be embodied as the default parameter in step S101. Each communication parameter search interval is set under the reference of the parameter and PRBS detection (pseudo random code detection) is carried out, and the error rate calculated under each group of parameter group can be stored in the buffer space in the IC in the detection process.
Preferably, in order to shorten the training range and reduce the training duration, before the above steps are performed, the following steps may be further performed before the pair of channel buffers of the transceiver is configured to close the internal loop:
step 2, carrying out pseudo-random code detection on the transceiver to obtain an internal loopback error rate;
and 3, detecting the transceiver by utilizing the internal loopback error rate.
That is, a transceiver channel buffer linked to the nth IC may be configured as an internal loopback (e.g., tx is connected to rx inside the transceiver as shown in the transceiver N of fig. 2) for link training. The link training method is to set the PRBS pseudo random code generator and checker of the Nth IC, select the appropriate pseudo random code (such as PRBS7, PRBS9, PRBS11, PRBS13, PRBS15, PRBS23, PRBS31 …) and perform PRBS detection. The PRBS detection aims to enable a sending end to send irregular and random signals of 0 and 1, enable a receiving end to recover the clock frequency of the receiving end according to the data of 0 and 1 which are constantly changed when the receiving end receives the signals, and configure a PRBS checker at the receiving end to confirm whether the data of the sending end is correct or not and calculate the error rate in an Nth IC.
Specifically, if the configuration parameters are detected to be wrong, the corresponding preset communication parameters are reconfigured for the link; and if the physical defect of the transceiver is detected, outputting corresponding defect information. It can detect the configuration problem of single transceiver (missing or failed parameter configuration, or wrong parameter configuration, etc.) or the inherent physical defect (such as unable to send signal, unable to receive signal, etc.) in advance.
And S104, selecting target communication parameters from different communication parameters by combining the error rates under different communication parameters and correspondingly monitored power consumption and temperature.
And the most suitable target communication parameter can be selected from different communication parameters by combining the error rate, the power consumption and the temperature under different communication parameters. For example, selecting a communication parameter corresponding to the lowest power consumption as a target image parameter with the error rate within a reasonable range; or selecting the communication parameter corresponding to the lowest power consumption as the target image parameter when the temperature is in a reasonable range; or selecting the communication parameters corresponding to the conditions that the error rate is in a reasonable range and the temperature and the power consumption meet the minimum requirements as the target communication parameters.
And S105, configuring target communication parameters for the link, and carrying out communication based on the target communication parameters by using the transceiver.
After the target communication parameters are selected, the target image parameters are configured into the link such that the transceiver communicates based on the target communication parameters.
The communication parameters may specifically include at least one of equalization parameters and pre-emphasis parameters.
By applying the method provided by the embodiment of the application, the connection information of the link corresponding to the transceiver newly inserted into the system is obtained, and the corresponding preset communication parameters are configured for the link according to the connection information; after the transmission power consumption of the optical module and the optical fiber jumper corresponding to the link is configured, the temperature and the power consumption of the link are monitored; under the condition of continuously adjusting communication parameters, carrying out pseudo-random code detection on the link to obtain error rates under different communication parameters; selecting target communication parameters from different communication parameters by combining the error rates under different communication parameters and correspondingly monitored power consumption and temperature; target communication parameters are configured for the link and communication is performed with the transceiver based on the target communication parameters.
In the application, after a new transceiver is inserted into the system, the connection information of the corresponding link is firstly acquired, and then the corresponding preset communication parameters are configured for the link according to the link information. In order to facilitate selection of appropriate communication parameters, after corresponding preset communication parameters are configured for the link, transmission power consumption of the corresponding optical module and the optical fiber jumper is configured for the link, and temperature and power consumption are monitored. And then, continuously adjusting communication parameters, and monitoring pseudo-random codes of the link, thereby obtaining the error rates under different communication parameters. And selecting required target communication parameters from different communication parameters by combining the error rates under different communication parameters and correspondingly monitored power consumption and temperature, configuring the target communication parameters for the link, and finally carrying out communication based on the target communication parameters by using the transceiver. It can be seen that in the present application, detecting the signal and adapting the communication parameters of the optimized link at the moment of link establishment can adapt different communication parameters at different ambient temperatures to increase the stability of channel data transmission and reduce the system power consumption.
It should be noted that, based on the above embodiments, the embodiments of the present application also provide corresponding improvements. In the preferred/improved embodiment, the same steps as those in the above embodiment or corresponding steps may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the preferred/improved embodiment herein.
In a specific embodiment of the present application, the step S105, in combination with the bit error rates under different communication parameters and the correspondingly monitored power consumption and temperature, selects a target communication parameter from the different communication parameters, including:
step one, acquiring communication requirements of an application scene;
and step two, selecting target communication parameters meeting communication requirements from different communication parameters by combining the error rates under different communication parameters and correspondingly monitored power consumption and temperature.
The communication requirement may specifically be at least one of a temperature requirement, a power consumption requirement, and a bit error rate requirement. Based on the communication requirement, target communication parameters meeting the communication requirement can be selected from different communication parameters according to the error rates under different communication parameters and correspondingly monitored power consumption and temperature.
For example, the following steps are carried out: the equalization parameters of the receiving end and the pre-emphasis parameters of the transmitting end can be continuously adjusted to find out a parameter list lower than the error rate, parameters such as the temperature of a transceiver and the temperature and the power of an optical module and an optical fiber jumper are calculated and recorded at present, the parameters and the parameters of each group of the receiving end and the transmitting end lower than the error rate are stored in a buffer memory space of an Nth IC, and the recording format is as follows (after the training, the parameter list conforms to the parameter example that the BER value is less than 5.6x10 < -10 >) -10):
| communication parameters | Link rate | Bit Error Rate (BER) | Temperature of transceiver | IC power |
| A | 25G | 6.2x10^-11 | 40 | 35w |
| B | 25G | 2.4x10^-11 | 42 | 32w |
| C | 25G | 4.8x10^-10 | 41 | 30w |
The communication parameters may include a receiving end equalization parameter and a pre-emphasis parameter of the transmitting end. That is, parameters, temperature and power parameters, of the receiving end and the sending end of the cache can be transmitted back to the management center through PCIe or other transmission protocols, so that the system can select an appropriate parameter value according to the requirements of different application scenarios, and under the parameter meeting the requirement of the bit error rate of the link, the lowest power consumption parameter value is selected according to the current environment temperature and the power consumption of different parameters generated in the nth IC.
As shown in fig. 2 and fig. 3, the management center may be specifically a management center other than the respective IC cards, so that the management center can obtain the record table corresponding to all links in the system as shown in the above table, and in practical applications, the communication parameters may also be selected in combination with the global situation.
