Detailed ways

The principle and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are given only to enable those skilled in the art to better understand and implement the present application, rather than to limit the scope of the present application in any way. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of this application to those skilled in the art.

The technical solution of the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

In order to better illustrate the technical solutions of the embodiments of the present application, the general bus system of the prior art is first described here, and the technical solution of the present application is more accurately described by comparing with the bus system in the prior art.

Fig. 1 shows a schematic diagram of connection relationship of a bus system in the prior art.

As shown in Figure 1, host 1, host 2, and host 3 may be physical hosts or virtual hosts. A single physical host or virtual host on the host side shares a communication channel of the system bus, through which multiple shared slave devices are accessed. For example: slave device one, slave device two and slave device three. When multiple sets of access occur, when the host performs data access through the communication channel of the system bus, it needs to be arbitrated by the host side, and then data transmission is performed through the communication channel of the system bus in turn. On the slave port, if there are multiple hosts that need to access the same slave device at the same time, they also need to go through the arbitration mechanism of the slave device, and then access the slave device in turn. Therefore, for a certain subsystem on the host side, the efficiency of data transmission depends on a single bandwidth limit, such as subsystem one in FIG. 1 .

FIG. 2 shows a schematic diagram of a connection relationship of a multi-path virtualized bus system according to an embodiment of the present application.

As shown in FIG. 2 , the multi-channel virtualized bus system implemented in the present application includes multiple communication channels and channel configuration devices (not shown in the figure). Communication channels are used for communication between the host and the system bus. Wherein, the multiple communication channels are configured to have different address spaces, which are shown as communication channel 1 and communication channel 2 here. In practical applications, other communication channels may also be included. The number of communication channels is set according to actual requirements, which is not limited in this application. The channel configuration device is used to obtain the current address space between the host and the system bus, and control the communication channel between the host and the system bus according to the current address space and channel configuration data. Wherein, the channel configuration data is used to show the configuration rule of the host side for the communication channel used between the host and the system bus.

Specifically, the host side may be configured with multiple hosts, and each host has multiple communication channels with the system bus. For example, there may be two channels of communication channel 1 and communication channel 2 between host 1 and the system bus. When the current address space between the host and the system bus is address space 1, the current host communicates with the system through communication channel 1; when the current address space between the host and the system bus is address space 2, the current address space between the host and the system communicate through communication channel two. Host 2 can also communicate with the system bus through communication channel 1 and communication channel 2, and the address space between host 2 and the system bus is not shown in the figure. Similarly, for the host computer 3, it can also communicate with the system bus through the communication channel 1 and the communication channel 2. It should be noted here that in practical applications, more communication channels may be set according to requirements.

The connection between the host and the system bus can be realized in the following way: based on the common connection between the host and the system bus with only one communication channel, a simple mirroring method is used to connect the additional communication channel. For example: based on the connection between host one and communication channel one of the system bus, the connection relationship between host one and communication channel two of the system bus is consistent with the connection relationship between host one and communication channel one of the system bus. Similarly, based on the connection between host two and communication channel one of the system bus, the connection relationship between host two and communication channel two of the system bus is consistent with the connection relationship between host two and communication channel two of the system bus. Communication channel three can also be added here, based on the connection between host one and communication channel one of the system bus, the connection relationship between host one and system bus communication channel three is consistent with the connection relationship between host one and system bus communication channel one.

The communication configuration device can be configured for each subsystem of the host end, or one communication configuration device can be configured for the entire host end. The channel configuration device is used to obtain the current address space between the host and the system bus, and control the communication channel between the host and the system bus according to the current address space and channel configuration data.

For example, the communication configuration device can obtain the communication load of the first communication channel corresponding to the current address space, and when the communication load of the first communication channel satisfies the first setting condition, the second communication between the control host and the system bus The channel communicates, and the communication load of the second communication channel is less than the set load.

Specifically, the data bandwidths that can be carried by multiple communication channels may be different. For example: the bandwidth that can be carried by the second communication channel is higher than the bandwidth that can be carried by the first communication channel. When the communication load is greater than the set load threshold, the communication channel between the first host and the system bus can be switched to the second communication channel.

Furthermore, the communication load between the host and the system bus may also be predicted, and the channel configuration data is configured for the host according to the predicted predicted load. For example: the bandwidth that can be carried by the second communication channel is higher than the bandwidth that can be carried by the first communication channel. If the predicted load between host one and system bus is less than the bandwidth that communication channel one can carry, then the channel configuration data between host one and system bus can be configured as "communication channel one is preferred between host one and system bus". For communication, when the real-time load between host one and the system bus is greater than the set load threshold, the host one and the system bus communicate through channel two." If the predicted load between host one and the system bus is greater than the bandwidth that communication channel one can carry is less than the bandwidth that communication channel two can bear, then the channel configuration data between host one and system bus can be configured as "host one and The communication between the system buses is preferentially carried out through the communication channel 2, and when the real-time load between the host 1 and the system bus is less than the set load threshold, the communication between the host 1 and the system bus is carried out through the channel 1". Furthermore, if the predicted load between Host 1 and the system bus is greater than the bandwidth that can be carried by the communication channel 2, the channel configuration data between Host 1 and the system bus can be configured as "between Host 1 and the system bus at the same time Channel 1 and communication channel 2 communicate, and according to the real-time load between host 1 and the system bus, close communication channel 1 or communication channel 2".

In addition, the communication channel configuration device can also configure other channel configuration data according to actual needs, for example, the communication channel between the host and the system bus can be configured according to the time period, which is not limited in this application.

In this embodiment of the present application, multiple communication channels are connected in the same manner between the host and the system bus.

For example, host 1, host 2, and host 3 are multiple hosts configured on the host side, all of which are configured on subsystem 1 on the host side. The host computer 1 can also choose to communicate with the system bus through the communication channel 1 or the communication channel 2 according to the configuration, so as to meet the requirement of data flow separation. Host 1 can also use communication channel 1 and communication channel 2 to communicate with the system bus according to the configuration, so as to meet the application requirements of high bandwidth.

It should be noted here that the multiple hosts at the host end may be multiple physical hosts, or multiple virtual hosts configured on the same physical host.

In this embodiment of the present application, the address space of the communication channel includes at least a physical address identifier and a channel identifier, and multiple channels corresponding to the same host have the same physical address identifier and different channel identifiers.

Here, it needs to be explained that the address space between the host and the system bus can add 1~2 channel identifiers on the basis of the physical address identifier in the original communication data. Of course, the number of channel identifiers here can be adjusted according to the needs. setting, which is not specifically limited in this application.

Specifically, referring to the connection mode in which host 1 communicates with the system bus through communication channel 1 or communication channel 2 in FIG. Communication channel one communicates with the system bus. When the current address space between the host and the system bus is obtained as address space 2, it means that the current host one and the communication channel two communicate with the system bus.

The channel configuration device can control the communication channel between the host and the system bus according to the current address space and channel configuration data. For example, if the data transmission rate between the master 1 and the slave device through the system bus is high or the data transmission volume is relatively large, the communication channel 1 is fixedly configured for the master 1, and other masters communicate with the system bus through the communication channel 2. Then no matter whether the current address space between the first host and the system bus is address space 1 or address space 2, the communication between the first host and the system bus is controlled according to the channel configuration data through the communication channel one.

In this embodiment of the present application, the channel configuration data is used to show the host side's configuration rules for the communication channel used between the host and the system bus. Here, the host side can set channel configuration rules according to the priorities of multiple hosts, the data transmission bandwidth requirements when the host communicates with the system bus, and the real-time load of multiple communication channels. For example: the host side can configure a fixed communication channel for a fixed host. The host side can also configure a fixed communication channel for a fixed host in a fixed time period, and share multiple communication channels with other hosts in other time periods. The channel configuration data can also be set to dynamically allocate communication channels according to the real-time load conditions of the system. Therefore, according to the actual requirement for communication between the host and the system bus, the efficiency of data transmission between the host and the system bus is maximized.

FIG. 3 shows a schematic diagram of a connection relationship of a multi-path virtualized bus system according to another embodiment of the present application. In this embodiment of the present application, the channel configuration device includes a monitoring unit and a configuration unit. The monitoring unit detects the communication load of the first communication channel corresponding to the current address space. When the communication load of the first communication channel satisfies the first set condition, the configuration unit communicates with the system bus through the second communication channel, and the communication load of the second communication channel is less than the set load.

In this embodiment of the present application, the configuration unit may be a unified configuration unit configured for the host side, and configures all communication channels between the host and the system bus. It is also possible to set up a configuration unit for each subsystem on the host side, which is responsible for the configuration of communication channels between all hosts and the system bus under the subsystem. As for the monitoring unit, a monitoring unit can be added for each host to detect the real-time communication load of each host, for example, the data bandwidth between the host and the system bus. Therefore, when the real-time communication load of one of the communication channels is obviously greater than that of other communication channels, the host and system bus that communicate through this communication channel are switched to communicate through other communication channels. Here, the criterion for judging that the real-time communication load of one of the communication channels is obviously greater than that of other communication channels may be set according to actual needs, which is not specifically limited in this application. In addition, during actual application, a monitoring unit may also be configured for one or more hosts among multiple hosts according to requirements, which is not specifically limited in this application.

It should be noted that Fig. 3 shows the solution of configuring a monitoring unit for each host. In actual application, a monitoring unit can be configured for a subsystem on the host side, or a monitoring unit can be configured for a physical host , and similarly, other configuration schemes may also be adopted, which is not specifically limited in this application.

Further, in this embodiment of the present application, when it is detected that a new host is added to the host end, the communication load of multiple communication channels between the host end and the system bus is detected, and the new host is further calculated according to the communication load of the multiple communication channels. The host configures the communication channel. For example: you can comprehensively analyze the communication load of each host in each time period, choose to configure a constant communication channel for the new host, or configure different communication channels for the new host in different time periods. In addition, the new host can also be configured to share multiple communication channels with other hosts, and the communication channel with the highest transmission efficiency can be configured for each host according to the communication load of each communication channel detected in real time.

In the multi-channel virtualized bus system, control method, chip, and electronic device in the embodiment of the present application, the virtualized bus system includes multiple communication channels, and the communication channels are used for communication between the host and the system bus, and the multiple communication channels are Configured to have different address spaces, the channel configuration device obtains the current address space between the host and the system bus, and controls the communication channel between the host and the system bus according to the current address space and channel configuration data. Therefore, communication channels can be added as data paths in multiple subsystems and system buses configured on the host side, and multiple communication channels can be distinguished by address space, effectively increasing the data bandwidth without affecting the system connection function. By configuring the address space, the coordinated and unified control of the bandwidth between multiple communication channels can be achieved, and the dynamic data flow balance can be further achieved, thereby significantly improving the access efficiency of the system.
