Detailed Description
The principles and spirit of the present application will be described below with reference to a number of exemplary embodiments. It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and to implement the present application, and do not 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 solution of the present application is further elaborated below with reference to the drawings and the specific embodiments.
In order to better illustrate the technical solution of the embodiment of the present application, a general bus system in 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 connection relationship of a bus system in 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 on the host side shares a communication channel of the system bus through which multiple shared slave devices are accessed. For example: the first slave device, the second slave device and the third slave device. When multiple groups of access occur, the host needs to arbitrate through the host end when performing data access through the communication channel of the system bus, and then performs data transmission through the communication channel of the system bus in sequence. If multiple masters all need to access the same slave equipment at the same time, the slaves need to access the slave equipment sequentially after passing through an arbitration mechanism of the slave equipment. Thus, for a certain subsystem at the host side, the efficiency of data transmission depends on a single bandwidth limit, such as the subsystem in fig. 1.
Fig. 2 is a schematic connection diagram illustrating a multi-channel virtualized bus system according to an embodiment of the present application.
As shown in fig. 2, the multi-channel virtualization bus system implemented in the present application includes a plurality of communication channels and a channel configuration device (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 practical application, other communication channels may also be included. The number of the communication channels is set according to actual requirements, and the number is not limited in the 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 for showing the configuration rule of the host for the communication channel used between the host and the system bus.
Specifically, the host side may be configured with a plurality of hosts, and each host has a plurality of communication channels with the system bus. For example: a first communication channel and a second communication channel can be arranged 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 can be performed through the first communication channel and the second communication channel. It should be noted here that in practical applications, more communication channels may be set according to requirements.
The connection mode between the host and the system bus can be realized by adopting the following modes: based on the connection mode that only one communication channel exists between the general host end and the system bus, the increased communication channels are connected by adopting a simple mirror image method. For example: based on the connection of the first host computer and the first communication channel of the system bus, the connection relationship of the second communication channel between the first host computer and the system bus is consistent with the connection relationship of the first host computer 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 consistent with the connection relationship between the second host and the second communication channel of the system bus. And a third communication channel can be added, and the connection relationship of the third communication channel between the first host and the system bus is consistent with the connection relationship of the first host and the first communication channel of the system bus based on the connection of the first host and the first communication channel of the system bus.
The communication configuration device can be configured for each subsystem of the host side, or can be configured for one communication configuration device of 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 the 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 apparatus may obtain a communication load of a first communication channel corresponding to the current address space, and when the communication load of the first communication channel satisfies a first setting condition, perform communication between the control host and the system bus through a second communication channel, where the communication load of the second communication channel is smaller than the setting load.
In particular, the data bandwidth that can be carried by the plurality of communication channels may be different. For example: the bandwidth which can be carried by the communication channel II is higher than that of the communication channel I. And when the communication load is greater than the set load threshold value, switching the communication channel between the first host and the system bus to a second communication channel.
Furthermore, 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 through prediction. For example: the bandwidth which can be carried by the communication channel two is higher than that which can be carried by the communication channel one. If the predicted load between the first host and the system bus is less than the bandwidth that can be carried by the first communication channel, the channel configuration data between the first host and the system bus may be configured as "the first host and the system bus preferentially communicate through the first communication channel, and the first host and the system bus communicate through the second channel when the real-time load between the first host and the system bus is greater than the set load threshold". If the predicted load between the first host and the system bus is greater than the bandwidth that can be borne by the first communication channel and less than the bandwidth that can be borne by the second communication channel, the channel configuration data between the first host and the system bus can be configured to be 'communication between the first host and the system bus preferentially through the second communication channel', and communication between the first host and the system bus through the first channel 'when the real-time load between the first host and the system bus is less than the set load threshold'. Further, if the predicted load between the first host and the system bus is greater than the bandwidth that can be carried by the second communication channel, the channel configuration data between the first host and the system bus may be configured as "the first host and the system bus communicate via the first channel and the second communication channel simultaneously, and the first communication channel or the second communication channel is closed according to the real-time load between the first host 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 may be configured according to the time period, which is not limited in this application.
In this embodiment of the present application, the plurality of communication channels are connected between the host and the system bus in the same manner.
For example, the first host, the second host and the third host are a plurality of hosts configured at the host end, and are all configured on the subsystem at the host end. 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 the configuration so as to meet the requirement of data flow separation. The first host can also use the first communication channel and the second communication channel to communicate with the system bus according to the configuration, so as to meet the application requirement of high bandwidth.
Here, the plurality of hosts on 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 at least includes a physical address identifier and a channel identifier, and a plurality of channels corresponding to the same host have the same physical address identifier and different channel identifiers.
It should be noted that, the address space between the host and the system bus may be added with a 1~2 bit channel identifier based on the physical address identifier in the original communication data, of course, the bit number of the channel identifier may be set as needed, and the present application is not limited specifically.
Specifically, referring to fig. 2, in a 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 and the first communication channel communicate with the system bus. When the current address space between the host and the system bus is acquired as the address space 2, the current host and the communication channel two are explained to 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 the channel configuration data. For example: the first host computer is fixedly configured with the first host computer through a high data transmission rate requirement or a large 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. Whether the current address space between the first host and the system bus is the address space 1 or the address space 2, the first host and the system bus are controlled to communicate through the first communication channel according to the channel configuration data.
In this embodiment of the present application, the channel configuration data is used to show the configuration rule of the host for the communication channel used between the host and the system bus. Here, the host may set the channel configuration rule according to priorities of the plurality of hosts, a data transmission bandwidth requirement 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 can configure a communication channel which is always fixed 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 a plurality of communication channels with other hosts in other time periods. The channel configuration data may also be set to dynamically allocate communication channels according to the real-time load conditions of the system, etc. 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 connection diagram 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. And the monitoring unit detects the communication load of the first communication channel corresponding to the current address space. And the configuration unit controls the host and the system bus to communicate through a second communication channel when the communication load of the first communication channel meets a first set condition, wherein 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 a unified configuration unit configured for the host side, and configure all communication channels between the host and the system bus. Or, a configuration unit may be provided for each subsystem at the host end, and is responsible for configuring communication channels between all hosts and the system bus under the subsystem. For the monitoring unit, a 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. Therefore, when the real-time communication load of one communication channel is obviously larger than that of the other communication channels, the host and the system bus which are communicated through the communication channel are switched to be communicated through the other communication channels. Here, the determination criterion that the real-time communication load of one of the communication channels is significantly greater than that of the other communication channels may be set according to actual requirements, which is not specifically limited in the present application. In addition, in the practical application process, one monitoring unit may be configured for one or more hosts of the multiple hosts according to requirements, which is not specifically limited in this application.
It should be noted that fig. 3 shows a scheme of configuring one monitoring unit for each host, in an actual application process, one monitoring unit may be configured for one subsystem at the host end, one monitoring unit may also be configured for one physical host, and 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, the communication loads of the plurality of communication channels between the host and the system bus are detected, and the communication channels are 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 is configured for the new host, or different communication channels are 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 the highest transmission efficiency is configured for each host according to the communication load of each communication channel detected in real time.
In the multi-channel virtualized bus system, the control method, the chip, and the electronic device according to the embodiments of the present application, the virtualized bus system includes a plurality of communication channels, the communication channels are used for performing communication between a host and a system bus, and the plurality of communication channels are configured to have different address spaces, and the channel configuration device obtains a current address space between the host and the system bus, and controls the communication channels between the host and the system bus according to the current address space and channel configuration data. Therefore, communication channels can be added in a plurality of subsystems and a system bus configured at a host end to serve as data channels, the communication channels can be distinguished by address spaces, and data bandwidth is effectively improved on the premise that the system connection function is not influenced. By configuring the address space, the bandwidth coordination and unified control among a plurality of communication channels can be realized, and the dynamic data flow balance is further realized, so that the access efficiency of the system is obviously improved.
