Embodiment 1
[0047] see figure 1 , is a schematic flowchart of a USB to SMI method provided in Embodiment 1 of the present invention, and see figure 2 , is a schematic diagram of connection of the converter, the CPU, and the network device provided in Embodiment 1 of the present invention. The method is applicable to converter 11, which is connected as figure 2 As shown, the converter 11 is connected to the CPU 12 through the USB bus, and the converter 11 is connected to the network device 13 through the SMI bus.
[0048]It should be noted that the CPU 12 accesses the converter 11 through the USB bus, and the converter 11 sends the operation instructions of the CPU 12 to the SMI bus, so that the CPU 12 can access any register of any network device 13 on the SMI bus. In this embodiment, the converter 11 is a peripheral hardware module. Using the USB interface as an extension, the conversion of the external module will not cause failure due to the replacement of the CPU12. In addition,...
Embodiment 2
[0071] see image 3 , is a schematic structural diagram of a USB-to-SMI device provided in Embodiment 2 of the present invention, which is suitable for a converter, the converter is connected to a CPU through a USB bus, and the converter is connected to a network device through an SMI bus; the Devices include:
[0072] The instruction receiving module 201 is configured to receive an operation instruction sent by the CPU through the USB bus when in an initial state; wherein the operation instruction includes a read instruction and a write instruction;
[0073] An instruction response module 202, configured to switch the initial state to a state corresponding to the operation instruction in response to the operation instruction, and receive operation data sent by the CPU;
[0074] A data conversion module 203, configured to convert the operation data into SMI operation data, and send the SMI operation data to the SMI bus to access the network device;
[0075] The operation com...
Embodiment 3
[0090] see Figure 4 , is a schematic structural diagram of a converter provided in Embodiment 3 of the present invention. The converter in this embodiment includes: a processor 301, a memory 302, and a computer program stored in the memory 302 and operable on the processor 301, such as a USB to SMI program. When the processor 301 executes the computer program, the steps in the above embodiments of the USB to SMI method are implemented. Alternatively, when the processor 301 executes the computer program, functions of the modules / units in the foregoing device embodiments are realized.
[0091] Exemplarily, the computer program can be divided into one or more modules / units, and the one or more modules / units are stored in the memory and executed by the processor 301 to implement the present invention . The one or more modules / units may be a series of computer program instruction segments capable of accomplishing specific functions, and the instruction segments are used to desc...
