Detailed Description
The principles and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present application and are not intended to limit the scope of the present application in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The technical scheme of the present application is further elaborated below with reference to the drawings and specific embodiments.
In order to better explain the technical solutions of the embodiments of the present application, a description is first given of a general bus system in the prior art, and the technical solutions of the present application are more accurately described by comparing with the bus system in the prior art.
Fig. 1 shows a schematic diagram of the connection of a bus system according to the prior art.
As shown in fig. 1, the first host, the second host and the third host may be physical hosts or virtual hosts. A single physical host or virtual host at the host side shares a communication channel of a system bus through which a plurality of shared slave devices are accessed. For example: the slave device I, the slave device II and the slave device III. When multiple groups of accesses occur, the host computer needs to arbitrate through the host computer end when performing data access through the communication channel of the system bus, and then sequentially performs data transmission through the communication channel of the system bus. In the slave port, if multiple hosts all need to access the same slave device, the slave device needs to pass through an arbitration mechanism of the slave device, and then sequentially access the slave device. Thus, for a certain subsystem at the host end, the efficiency of data transmission depends on a single bandwidth limit, such as the subsystem in fig. 1.
FIG. 2 is a schematic diagram illustrating 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-path virtualized bus system implemented in the present application includes a plurality of communication paths and path configuration means (not shown in the figure). The communication channel is used for communication between the host and the system bus. Wherein a plurality of said communication channels are configured to have different address spaces, here shown as communication channel one and communication channel two. In the practical application process, other communication channels can be also included. The number of the communication channels is set according to actual requirements, which is not limited in the present application. The channel configuration device is used for acquiring the current address space between the host and the system bus, and controlling the communication channel between the host and the system bus according to the current address space and the channel configuration data. 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 a plurality of hosts, each having a plurality of communication channels with the system bus. For example: there may be two channels, a first communication channel and a second communication channel, between the first host and the system bus. When the current address space between the host and the system bus is the address space 1, the current host and the system communicate through the first communication channel, and when the current address space between the host and the system bus is the address space 2, the current host and the system communicate through the second communication channel. For the second host, communication with the system bus may also be performed through the first communication channel and the second communication channel, and an address space between the second host and the system bus is not shown in the figure. Similarly, for the third host, communication with the system bus is also possible through the first communication channel and the second communication channel. It should be noted that in practical application, more communication channels may be set according to requirements.
The connection between the host and the system bus may be implemented as follows: based on the connection mode that only one communication channel exists between the general host side and the system bus, a simple mirror image method is adopted to connect the added communication channels. For example: based on the connection between the first host and the first communication channel of the system bus, the connection relationship between the first host and the second communication channel of the system bus is consistent with the connection relationship between the first host and the first communication channel of the system bus. Similarly, based on the connection between the second host and the first communication channel of the system bus, the connection relationship between the second host and the second communication channel of the system bus is identical to the connection relationship between the second host and the second communication channel of the system bus. The communication channel III can be added, and the connection relation between the host I and the communication channel III of the system bus is consistent with the connection relation between the host I and the communication channel I of the system bus based on the connection between the host I and the communication channel I of the system bus.
The communication configuration device may be configured for each subsystem of the host side, or may be configured for the whole host side. The channel configuration device is used for acquiring the current address space between the host and the system bus and controlling a communication channel between the host and the system bus according to the current address space and the channel configuration data.
For example, the communication configuration device may obtain a communication load of the first communication channel corresponding to the current address space, and when the communication load of the first communication channel meets a first set condition, the control host communicates with the system bus through a second communication channel, where the communication load of the second communication channel is smaller than the set load.
In particular, the data bandwidth that can be carried by the plurality of 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. The communication channel between the host one and the system bus may be switched to the communication channel two when the communication load is greater than the set load threshold.
Further, the communication load between the host and the system bus can be predicted, and channel configuration data can be configured for the host according to the predicted load obtained by prediction. 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 the host one and the system bus is smaller than the bandwidth that can be carried by the communication channel one, the channel configuration data between the host one and the system bus can be configured as "communication is performed between the host one and the system bus preferentially through the communication channel one", and when the real-time load between the host one and the system bus is greater than the set load threshold, communication is performed between the host one and the system bus through the channel two ". If the predicted load between the host one and the system bus is greater than the bandwidth that the communication channel one can carry and is less than the bandwidth that the communication channel two can carry, the channel configuration data between the host one and the system bus can be configured as "the communication between the host one and the system bus is preferentially carried out through the communication channel two", and when the real-time load between the host one and the system bus is less than the set load threshold value, the communication between the host one and the system bus is carried out through the channel one ". Further, if the predicted load between the host one and the system bus is greater than the bandwidth that can be carried by the communication channel two, the channel configuration data between the host one and the system bus may be configured to "communicate between the host one and the system bus through the channel one and the communication channel two at the same time, and close the communication channel one or the communication channel two according to the real-time load between the host one and the system bus.
In addition, the communication channel configuration device may also configure other channel configuration data according to actual requirements, for example: the communication channel between the host and the system bus, etc. may be configured according to a period of time, which is not limited in this application.
In this embodiment of the present application, the plurality of communication channels are connected in the same manner between the host and the system bus.
For example, the first host, the second host and the third host are multiple hosts configured on the host side, and are all configured on a subsystem on the host side. The first host computer can also select to communicate with the system bus through the first communication channel or the second communication channel according to configuration so as to meet the requirement of data flow separation. The first host computer can also use the first communication channel and the second communication channel to communicate with the system bus according to configuration so as to meet the application requirement of high bandwidth.
Here, the plurality of hosts at the host side may be a plurality of physical hosts, or may be a plurality of 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 should be noted that, the address space between the host and the system bus may be increased by 1-2 bits of the channel identifier based on the physical address identifier in the original communication data, and of course, the number of bits of the channel identifier may be set as required, which is not specifically limited in this application.
Specifically, referring to fig. 2, in the connection manner in which the first host communicates with the system bus through the first communication channel or the second communication channel, when the current address space between the first host and the system bus is obtained as the address space 1, the first host is described as communicating with the first communication channel and the system bus. When the current address space between the host and the system bus is obtained as address space 2, it is explained that the current host communicates with the system bus through the second communication channel.
The channel configuration means may control a communication channel between the host and the system bus based on the current address space and the channel configuration data. For example: the first host computer is configured with the first communication channel fixedly through the higher data transmission rate requirement or the larger data transmission quantity between the system bus and the slave computer equipment, and the other host computers are communicated with the system bus through the second communication channel. Then communication between host one and the system bus via communication channel one is controlled according to the channel configuration data, whether the current address space between host one and the system bus is address space 1 or address space 2.
In this embodiment of the present application, channel configuration data is used to illustrate the configuration rules of the host side for the communication channels used between the host and the system bus. Here, the host side may set the channel configuration rule according to priorities of the plurality of hosts, data transmission bandwidth requirements when the hosts communicate with the system bus, real-time loads of the plurality of communication channels, and the like. For example: the host side may configure a fixed communication channel for a fixed host. The host side may also configure a fixed communication channel for a fixed host in a fixed period of time, and the other periods of time share multiple communication channels with other hosts. The channel configuration data may also be configured to dynamically allocate communication channels, etc., according to the real-time load conditions of the system. Therefore, according to the actual requirement of communication between the host and the system bus, the data transmission efficiency between the host and the system bus is improved to the maximum extent.
FIG. 3 is a schematic diagram illustrating a connection relationship of a multi-path virtualized bus system according to another embodiment of the application. In this embodiment of the application, the channel configuration device comprises a monitoring unit and a configuration unit. And 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 meets a first set condition, the configuration unit performs communication between the control host and the system bus through a second communication channel, and the communication load of the second communication channel is smaller than the set load.
In this embodiment of the present application, the configuration unit may be configured to configure a unified configuration unit for the host side, and configure all communication channels between the host and the system bus. A configuration unit can be set for each subsystem at the host end, and is responsible for the configuration of communication channels between all hosts and a system bus under the subsystem. For the monitoring unit, one monitoring unit may be added for each host, to detect the real-time communication load of each host, for example: data bandwidth between the host and the system bus. So that when the real-time communication load of one of the communication channels is significantly greater than that of the other communication channels, the host and the system bus communicating through the communication channel are switched to communicate through the other communication channels. The determination criteria for one of the communication channels that the real-time communication load is significantly greater than that of the other communication channels may be set according to actual requirements, which is not specifically limited in this application. In addition, in the actual application process, a monitoring unit may be configured for one or more hosts in the multiple hosts according to the requirement, which is not specifically limited in this application.
It should be noted that, in fig. 3, a scheme of configuring one monitoring unit with each host is shown, in the practical application process, one monitoring unit may be configured for one subsystem at the host side, one monitoring unit may also be configured for one physical host, and other configuration schemes may also be adopted, which is not limited in this application specifically.
Further, in this embodiment of the present application, when it is detected that the host side adds a new host, the communication loads of the plurality of communication channels between the host side and the system bus are detected, and the communication channels are further configured for the new host according to the communication loads of the plurality of communication channels. For example: the communication load of each host in each time period can be comprehensively analyzed, and a communication channel which is always fixed for a new host is selected to be configured, or a different communication channel is configured for the new host in different time periods. In addition, the new host can be configured to share a plurality of communication channels with other hosts, and the communication channel with highest transmission efficiency is configured for each host according to the communication load of each communication channel detected in real time.
In the multi-path virtualized bus system, the control method, the chip and the electronic device, the virtualized bus system comprises a plurality of communication channels, the communication channels are used for communication between a host and a system bus, the 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 the communication channels between the host and the system bus are controlled according to the current address space and channel configuration data. Therefore, communication channels can be added to a plurality of subsystems and system buses configured at the host end to serve as data paths, the plurality of communication channels can be distinguished by address space, and the data bandwidth is effectively improved on the premise that the connection function of the system is not affected. The bandwidth coordination and unified control among a plurality of communication channels can be realized by configuring the address space, and the dynamic data flow balance is further realized, so that the access efficiency of the system is remarkably improved.
