Fig. 2 is a flowchart illustrating a method for implementing a bus structure according to an embodiment of the present invention, which is applied to any device of the system on chip shown in fig. 1, and as shown in fig. 2, the method includes:
The data identification information is used for indicating equipment for processing bus input data.
In the process of bus input data transmission through a bus, the bus input data needs to be processed by a device in a bus structure of a system on chip, and before processing, the device in the bus structure judges whether the bus input data transmitted through the bus needs to be processed.
Therefore, the device in the system on chip may first obtain the data identification information in the bus input data, so that in the subsequent step, it may be determined whether the bus input data needs to be processed according to the data identification information.
Specifically, the device may detect whether the bus transmits bus input data in real time, and if it is detected that the bus transmits the bus input data to the device, the device may first obtain data of a specified field in the bus input data, so as to obtain data identification information in the bus input data.
It should be noted that each device in the bus structure of the system on chip has different functional modules, data identification information in the bus input data is used to determine whether the device can receive the bus input data, and the data identification information may be an IP (Internet Protocol) address or other information, which is not limited in this embodiment of the present invention.
After the device acquires the data identification information of the bus input data, the device can judge according to the acquired data identification information to determine whether the data identification information is consistent with the device identification information, so that in the subsequent steps, different operations can be executed on the bus input data according to the judgment result.
Specifically, the data identification information of the bus input data may be matched with the identification information of the device, and whether the data identification information is consistent with the preset identification information of the device is determined, and if the data identification information is consistent with the identification information of the device, it is indicated that the data identification information is successfully matched with the preset identification information of the device. And if the data identification information is inconsistent with the identification information of the equipment, indicating that the data identification information is unsuccessfully matched with the preset equipment identification information.
It should be noted that the preset device identification information and the device receiving the bus input data are both used to indicate the same device. When the bus input data is transmitted in the system on chip, each device needs to acquire the data identification information of the bus input data, and the data identification information of the bus input data and the device identification information are matched.
And step 203, receiving bus input data if the data identification information is successfully matched with the equipment identification information.
And after the matching is successful, the device in the system on chip can receive the bus input data transmitted by the bus and process the received bus input data.
Specifically, after the device receives the bus input data, the data type of the bus input data and the data type of the device identification information may be matched according to an event table stored in the device, and if the data type of the device identification information is consistent with the data type of the bus input data, the bus input data may be processed. And processing the data type of the bus input data consistent with the data type of the equipment identification information.
For example: the device is an analog-digital converter, the data type in an event table in the device can show that an analog signal is converted into a digital signal, the data type in the event table indicates the data type in the device identification information, when the data type of the bus input data is converted into the digital signal, the data type of the bus input data is consistent with the data type in the device identification information, the bus input data can be processed, the analog signal of the bus input data is converted to obtain the processed digital signal, and the device finishes processing.
It should be noted that at least one data type is stored in the event table in each device, the data type of the bus input data and the data type of the device identification information may be matched according to the stored event table, and if the data type of the bus input data and the data type of the device identification information are successfully matched, the bus input data is processed.
In summary, according to the bus structure implementation method provided by the present invention, after the device acquires the data identification information of the bus input data and the identification information of the device are consistent, the bus input data is received, and the device processes the received bus input data, so that the master device and the slave device are combined into one device, and the bus interconnection module is not required to perform parsing and arbitration, thereby solving the problem of low efficiency of the master device accessing the slave device due to the access of the master device to the slave device in the prior art, and improving the transmission efficiency of the bus input data.
Fig. 3 is a schematic flowchart of a method for implementing a bus structure according to another embodiment of the present invention, as shown in fig. 3, the method includes:
In at least one device of a bus structure in the system on chip, each device needs to detect whether a bus sends bus input data or not at any moment, and if the bus input data is not detected, the bus input data needs to be continuously detected; if the bus input data sent by the bus is detected, corresponding operation can be executed on the sent bus input data in the subsequent steps.
After detecting the bus input data sent by the bus, the device can continue to detect the bus input data sent by the bus.
Specifically, after the device detects the bus input data, it needs to perform subsequent processing on the bus input data, and if the bus input data is not detected, it needs to detect the bus input data in the bus transmission all the time.
And step 303, matching the data identification information with preset equipment identification information.
Since the process from step 302 to step 303 is similar to the process from step 201 to step 202, it is not repeated here.
And step 304, if the data identification information and the equipment identification information are not matched successfully, not receiving the bus input data.
If the data identification information and the device identification information fail to be matched, the bus input data is not received, but the bus input data sent by the bus is forwarded to other devices, so that the other devices execute similar operations as in steps 301 to 311 on the bus input data sent by the bus.
Specifically, corresponding to the system on chip in fig. 1, when the identification information of the bus input data is not consistent with the device identification information of the first device, the first device does not receive the bus input data and forwards the bus input data to the second device, the second device obtains the device identification information of the bus input data and matches the device identification information of the second device with the identification information of the bus input data, and when the second device identification information is not consistent with the identification information of the bus input data, the second device forwards the bus input data to the third device until the device identification information of a certain device is consistent with the identification information of the bus input data, the device receives the bus input data.
And 305, receiving bus input data if the data identification information and the equipment identification information are successfully matched.
The process of step 305 is similar to the process of step 203, and is not described herein again.
Step 306, determining whether the data type corresponding to the bus input data is consistent with the data type corresponding to the device identification information according to a pre-stored event table.
The method comprises the steps that an event table corresponding to an event which can be processed by the device is stored in each device in a bus structure of the system on chip, the event table stored in each device is different, the event table stored in advance in the device can comprise a data type of device identification information and is used for representing the data type which can be processed by the device, after bus input data are received according to the event table stored in the device in advance, the data type of the bus input data is matched with the data type corresponding to the device identification information, whether the data type of the bus input data exists in the event table or not is judged, and if the data type of the bus input data exists in the data type of the device identification information in the event table of the device, the bus input data need to be continuously processed in the subsequent steps.
Specifically, after the device receives the bus input data, it may first determine whether the device can process the received bus input data, and if it is determined according to the event table in the device that the data type of the bus input data is inconsistent with the data type in the device identification information, it indicates that the device cannot process the bus input data received by the device.
For example: the event table stored in the first device indicates the data types that can be processed by the first device, and the data types of the device identification information in the event table of the first device indicate that the data types can only be processed by the first device. The event table stored in the second device indicates the data types that the second device can process, and the data types of the device identification information in the event table of the second device can only be processed by the second device.
It should be noted that the event tables of each device are different, and if the device is an analog-to-digital converter, the data type of the device identification information in the event table in the device is to convert an analog signal into a digital signal, and when the data type of the bus input data is to convert an analog signal into a digital signal, the device can process the bus input data after receiving the bus input data.
And 307, if the data type corresponding to the bus input data is determined to be consistent with the data type corresponding to the equipment identification information, processing the bus input data to obtain the processed bus input data.
And after the data type in the bus input data received by the equipment is successfully matched with the data type in the equipment identification information, the equipment processes the bus input data, wherein the processed data type is the data type of the equipment identification information stored in the event table, and the processed bus input data is finally obtained.
Specifically, the device receives bus input data, matches the data type of the bus input data with the data type in the device identification information according to an event table pre-stored in the device, and processes the bus input data if the data type of the bus input data is consistent with the data type in the device identification information, so as to obtain the processed bus input data.
For example: if the device is an analog-to-digital converter, after the device receives the bus input data, if the data type of the device identification information in the event table stored in the analog-to-digital converter is consistent with the data type of the bus input data, the analog-to-digital converter can process the bus input data and convert the analog signal of the bus input data into a digital signal.
It should be noted that, in practical applications, the bus input data may include data of a plurality of data types, where a data type of a part of the data in the bus input data is consistent with a data type in the data types corresponding to the device identification information, but a data type of the remaining data in the bus input data is inconsistent with a data type in the data types corresponding to the device identification information, the device may process a consistent data type in the data types of the bus input data and the corresponding data types in the device identification information, and for some data types in the bus input data that are inconsistent with a data type corresponding to the device identification information, at least one data processing request may be generated according to an inconsistent data type in the data types of the bus input data and the corresponding data types of the device identification information, at least one target processing request is sent, the device may receive at least one target processing information corresponding to the at least one target processing request sent and processed by the at least one target device.
For example: if the first device receives the post-bus input data, judging that the data types of the bus input data exist in the data types in the device identification information of the first device and are inconsistent according to an event table stored in the first device in advance, processing the data type of the device identification information in the first device and the data type of the bus input data, generating at least one data processing request, wherein the at least one data processing request comprises identification information of at least one target device, and if the target device comprises: and the second device and the third device respectively process the at least one data processing request, and the device receives target processing information obtained after the second device and the third device respectively process the at least one data processing request. And finally, the first equipment obtains the processed bus input data.
When the event table stored in the analog-to-digital converter stores the data type of the bus input data, the analog signal of the received bus input data may be converted into a digital signal by processing the data type.
And 308, displaying that the processed bus input data is in a finished state.
After the device processes the received bus input data, the processed bus input data is obtained, at this time, the device completes processing of the bus input data, and displays that the processing state of the bus input data is a completion state on the device, and the completion state is used for indicating that the processing of the bus input data is completed. Of course, the display state may also include: a wait state to indicate that bus transaction data is being processed, and a process failure state. The processing failure state is used for indicating that the device fails to process data on the bus.
In addition, a user can observe the processing state of the bus input data on the device through the device, and real-time monitoring of the data processing condition in the bus structure of the system on chip is facilitated.
Specifically, when the device receives the bus input data and processes the bus input data, the device displays that the bus input data is being processed and please wait for a state, and when the bus input data processing fails due to a problem in the bus input data processing, the device displays that the bus input data processing fails, and the device can reprocess the bus input data.
It should be noted that, the device updates each processing stage of the bus input data processing, and finally, after the bus input data processing is completed, the device displays that the bus input data processing is in a completed state.
Wherein the data processing request includes target device identification information.
If the data type corresponding to the bus input data is determined to be inconsistent with the data type corresponding to the equipment identification information, the matching is failed, the data type of the bus input data is not in the data type corresponding to the equipment identification information, the equipment is further indicated to be incapable of processing the bus input data, a data processing request is generated, and other equipment is required to assist in processing the bus input data.
Specifically, when a device cannot process received bus input data, a data processing request is generated according to the data type of the bus input data, so that other devices can process the bus input data which cannot be processed by the device.
It should be noted that the data processing request is generated according to the device identification information in the device event table, for example, if the data type of the device identification information of the first device in the event table of the first device is not consistent with the data type of the received bus input data, the data processing request needs to be generated, and if the data type of the device identification information of the first device in the event table of the third device is consistent with the data type of the bus input data, the generated data processing request may include the device identification information of the third device, and the third device receives the data processing request through the third device identification information in the data processing request.
And step 310, sending a data processing request to enable the target device to receive and process the data processing request according to the identification information of the target device, so as to obtain target processing information.
And after the equipment for receiving the bus input data cannot process the bus input data, generating a data processing request and sending the data processing request, so that the target equipment performs matching according to the target equipment identification information carried in the data processing request, and after the matching is successful, the target equipment receives the data processing request.
Specifically, after the device receiving the bus input data sends a data processing request to the target device, so that the target device can perform matching according to the data type of the device identification information in the event table and the data type of the data processing request, if the data type of the data processing request is stored in the data type of the device identification information in the event table stored in the target device, the target device processes the data processing request to obtain processed target processing information, and feeds back a result after processing the data processing request to the device sending the data processing request to obtain fed back target processing information.
And 311, receiving the target processing information sent by the target equipment.
And when the target equipment processes the data processing request, target processing information is obtained, and the target equipment sends the target processing information.
Specifically, after receiving a data processing request feedback result sent by the target device, the device updates the processing state of the bus input data, and updates the bus input data processing waiting state into a bus input data processing completion state so as to show the bus input data processing completion state to the user.
In summary, in the method for implementing a bus structure provided in the embodiments of the present invention, after the data identification information of the device input data through the bus is matched with the device identification information, if the device can process the bus input data after the matching is successful, the device processes the bus input data and displays a processing completion state, and if the device cannot process the bus input data, the device generates a data processing request and sends the data processing request to the target device, so that the target device receives the data processing request through the identification information of the target device carried in the data processing request, and the target device receives the data processing request through the identification information of the target device carried in the data processing request and processes the data processing request to obtain the target processing information. And the final equipment receives the target processing information sent by the target equipment and displays the completion of the processing of the bus input data, thereby improving the transmission efficiency of the bus input data in bus transmission.
