[0002] Multiplexer, as a multi-channel output selection device, is widely used in the interconnection between the host and peripheral slaves of the system on chip.

[0003] When a multiplexer performs a decoding operation, it needs decoding parameters as the execution basis. In the prior art, the decoding parameters are usually decoded manually, that is, the developer pre-calculates the decoding parameters required by the multiplexer, and then assigns the decoding parameters to the multiplexer. The multiplexer performs subsequent decoding operations based on the decoding parameters.

[0004] However, this decoding method not only consumes high manpower and time costs, but also has low efficiency in obtaining decoding parameters.

[0029] Embodiment 1

[0030] Figure 1This is a flowchart of a multiplexer parameter configuration method provided in the first embodiment of the present invention. This embodiment is applicable to the case of obtaining the decoding parameters of the multiplexer based on the address routing file. The method can be executed by a multiplexer parameter configuration device. The multiplexer parameter configuration device can be implemented in the form of hardware and / or software. The multiplexer parameter configuration device can be configured in an electronic device such as a terminal device. Figure 1 As shown, the method includes:

[0031] S101, establishing an address routing file; wherein the address routing file includes address routing information of each multiplexer and routing object information of a slave device.

[0032] The address routing information is the path information used to guide the transmission of data packets from the source address to the target address; in the embodiment of the present invention, the address routing file records the name of each multiplexer and the address routing information of each multiplexer; the routing object information represents the status information of the activatable routing. Since each multiplexer is connected to one or more slave devices for communication, and each slave device corresponds to different multiple target addresses, the address routing file actually reflects the address information of the slave devices to which each multiplexer is respectively connected.

[0033] Optionally, in an embodiment of the present invention, the address routing information of the multiplexer includes a start address, an end address, and an address space size; the routing object information of the slave device includes a slave device name. As shown in Table 1, the address routing file records the names of each multiplexer, the names of the slave devices to which each multiplexer is connected, and information such as the start address, end address, and address size of each slave device.

[0034] The slave device is an external device of the system on chip where the multiplexer is located, for example, a slave device based on the Advanced High-performance Bus (AHB) (i.e., an AHB device) and a slave device based on the Advanced Peripheral Bus (APB) (i.e., an APB device); accordingly, the multiplexer includes a multiplexer based on the Advanced High-performance Bus protocol and a multiplexer based on the Advanced Peripheral Bus protocol, so as to realize data transmission between the host device and the AHB device and the APB device; the address routing file can be a MemMap file, which records the address mapping relationship of the system on chip, so as to realize memory mapping management in the embedded system.

[0035] Table 1 Address routing file

[0036]

[0037] At the same time, in order to ensure the support for the extended functions of the multiplexer, a certain address space can be reserved for each multiplexer so that when the multiplexer is connected to a new slave device, it has the communication function for the newly added slave device, and the above reserved information can also be recorded in the address routing file. The "slave device name" in each reserved information is represented by the reserved mark "Reserved", and the "starting address", "ending address" and "address size" in the reserved information respectively indicate the starting address, ending address and address size of the reserved space.

[0038] S102: Use an automated tool to analyze the address routing file, extract the address routing information of the multiplexer and the routing object information of the slave device, and obtain the decoding parameters of each of the multiplexers.

[0039] An automation tool refers to a software program that can automatically perform specific tasks; in an embodiment of the present invention, the automation tool specifically refers to a file analysis tool, which can automatically perform data extraction and data analysis functions, for example, analyzing and extracting the contents of an address routing file according to preset rules and algorithms; the address routing information of the multiplexer and the routing object information of the slave device in the address routing file can be extracted by the automation tool; in particular, the automation tool can match the file format of the address routing file, and different automation tools can be selected for address routing files of different formats; optionally, in an embodiment of the present invention, the functional type of the automation tool is not specifically limited.

[0040] Decoding parameters refer to the address parameters and data parameters required by the multiplexer when performing decoding operations. In addition to including the address input port and the data input port, as well as the address routing information of the multiplexer and the routing object information of the slave device recorded in the address routing file, for example, in the above technical solution, in addition to the starting address, ending address, address size and slave device name of the slave device connected to each multiplexer, other configuration parameters calculated based on the above parameters may also be included.

[0041] For example, the decoding parameters may include the total address space, the number of slave devices, the merged start address, the merged end address, etc.; wherein the total address space refers to summing up the address sizes corresponding to each slave device under the "Address Size" column of the current multiplexer to calculate the total address space corresponding to each multiplexer; the number of slave devices refers to summing up the numbers of each slave device in the "Slave Device Name" column of the current multiplexer to calculate the total number of slave devices corresponding to each multiplexer.

[0042] As described in the above technical solution, the addresses between multiple slave devices corresponding to each multiplexer are often continuous. At this time, it is necessary to merge the above continuous addresses and record the starting address (i.e., the merged starting address) and the ending address (i.e., the merged ending address) of the merged address space, so that the multiplexer can accurately know the specific range of the address space corresponding to itself, while reducing the data amount of the decoding parameters.

[0043] After the decoding parameters are calculated and obtained according to the pre-configured calculation rules, the developer can save them and configure them to the corresponding multiplexer; the current electronic device can also send the directly extracted decoding parameters and the calculated decoding parameters to the corresponding multiplexer through the matching communication interface; the multiplexer completes the parameter configuration update after obtaining the decoding parameters, and the updated multiplexer performs decoding operations according to the transmission data sent by the host device, and sends the decoding results to the corresponding slave device; thereby realizing the extraction, calculation and distribution of the decoding parameters.

[0044] like Figure 2 As shown, taking the multiplexer parameter configuration method in the above technical solution as an example, the multiplexer parameter configuration device includes an address file acquisition module 100 and a parameter configuration execution module 200; the address file acquisition module 100 is used to establish an address routing file; the parameter configuration execution module 200 is used to use an automated tool to analyze the address routing file, extract the address routing information of the multiplexer and the routing object information of the slave device, and obtain the decoding parameters of each of the multiplexers.

[0045] After establishing the address routing file, if the address file acquisition module 100 obtains an information change instruction issued by a host device, such as a central processing unit (CPU), it performs a corresponding update operation in the address routing file; wherein the information change instruction includes a multiplexer addition instruction, a multiplexer deletion instruction, a multiplexer modification instruction, a slave device addition instruction, and a slave device deletion instruction.

[0046] When a new multiplexer addition instruction is obtained, the address file acquisition module 100 inserts one or more data rows in the address routing file. The newly inserted data rows record the name of the newly added multiplexer and the name of the slave device connected to the newly added multiplexer, as well as the starting address, ending address and address size of the slave device. The number of newly added data rows is the same as the number of slave devices connected to the newly added multiplexer.

[0047] When a multiplexer deletion instruction is obtained, the address file acquisition module 100 deletes all data rows associated with the multiplexer in the address routing file, and the number of data rows is also the same as the number of slave devices connected to the multiplexer; when a multiplexer modification instruction is obtained, the address file acquisition module 100 modifies one or more parameter information of the current multiplexer in the address routing file, including modifying the name of the slave device connected to the current multiplexer, and modifying the starting address, ending address and address size of the slave device.

[0048] When a slave device addition instruction is obtained, the address file acquisition module 100 adds one or more data rows under the current multiplexer of the address routing file, each data row corresponds to a slave device, and fills in the relevant information of the slave device in the data row; when a slave device deletion instruction is obtained, the address file acquisition module 100 deletes one or more data rows under the current multiplexer of the address routing file, and the number of deleted data rows is also the same as the number of slave devices to be deleted.

[0049] In particular, after establishing the address routing file, the address file acquisition module 100 can also perform a repeatability check on the information in the address routing file, for example, judging whether there are repeated slave devices based on the slave device name; judging whether there are repeated cross-addresses based on the starting address and ending address of each slave device; in addition, since the host device may assign continuous addresses to slave devices under a multiplexer to facilitate the management of the address space, the address file acquisition module 100 can also perform a compliance check on the address information in the address routing file to determine whether the slave device addresses under each multiplexer are a continuous address space.

[0050] Optionally, in an embodiment of the present invention, the decoding parameters are saved in the form of a Verilog file. "Verilog" itself is a hardware description language that can describe the structure and behavior of digital system hardware in text form. In an embodiment of the present invention, the decoding parameters are saved in the form of a Verilog file, which is convenient for storing the decoding parameters and for parsing and obtaining the multiplexer.

[0051] Optionally, in an embodiment of the present invention, the address routing file includes reserved slave information; and the using of an automated tool to analyze the address routing file to extract the address routing information of the multiplexer and the routing object information of the slave device specifically includes: filtering the reserved slave information in the address routing file to extract the address routing information of the multiplexer and the routing object information of the slave device based on the non-reserved slave information in the address routing file.

[0052] Specifically, for the reserved slave information, it is actually a kind of planning information of the host device for the slave device. For the multiplexer, the use of the reserved information is not currently involved. At the same time, the address planning of the host device is also subject to the possibility of real-time change. Therefore, when extracting information, it is necessary to filter the reserved slave information in the address routing file, and only extract the address information that has been allocated for use, that is, the non-reserved slave information. This not only reduces the amount of extracted data in the address routing file and improves the efficiency of obtaining decoding parameters, but also avoids the multiplexer from parsing the reserved slave information, thereby resulting in no parsing results.

[0053] Optionally, in an embodiment of the present invention, the obtaining of decoding parameters of each of the multiplexers further includes: determining whether each multiplexer is a continuous routing address according to the address routing file; if it is determined that the current multiplexer is a continuous routing address, configuring a continuous address identifier for the current multiplexer; if it is determined that the current multiplexer is a non-continuous routing address, configuring a non-continuous address identifier for the current multiplexer.

[0054] Specifically, the routing addresses between the slave devices connected to the multiplexer may be continuous or discontinuous. For continuous routing addresses, a continuous address identifier is generated for the multiplexer configuration. At this time, the decoding parameters only need to include the continuous address identifier, the address size of each slave device, and the combined start address and end address. The multiplexer can parse and obtain the start address and end address corresponding to each slave device based on the above information, thereby reducing the data volume of the decoding parameters. At the same time, for discontinuous routing addresses, a discontinuous address identifier is generated for the multiplexer configuration. At this time, the decoding parameters also need to include the discontinuous address identifier to ensure the multiplexer's complete management of the address space, avoid address loss, and improve the accuracy of the decoding parameters.

[0055] The technical solution of the embodiment of the present invention, after establishing the address routing file, uses an automated tool to analyze the address routing file, extracts the address routing information of the multiplexer and the routing object information of the slave device, and obtains the decoding parameters of each multiplexer. In this way, while realizing the orderly management of the routing address of the slave device, it not only reduces the labor cost and time cost consumed in the decoding parameter acquisition process of the multiplexer, improves the acquisition efficiency of the decoding parameters, but also avoids the misinterpretation and missed interpretation phenomena existing in the manual decoding method, and improves the accuracy of the decoding result.
