The invention provides a method and equipment for acquiring peripheral electronic tag information. The equipment comprises a processor and a programmable logic device, and the programmable logic device is connected with peripheral through a single bus and connected with the processor through double buses. When the programmable logic device analyzes that the processor needs to read the electronic tag information of the peripheral, the programmable logic device sends an electronic tag information request through a single bus connected with the peripheral. After receiving a request for reading the electronic tag information of the peripheral, the peripheral returns the stored electronic tag information to the programmable logic device through the single bus connected with the programmable logic device. A receiving the electronic tag information, the programmable logic device converts the electronic tag information into information conforming to a dual-bus protocol according to the dual-bus protocol followed by the dual buses connected between the processor and the programmable logic device, and sends the information to the processor, so that the processor obtains the peripheral electronic tag information.
Description
Technical field [0001] The present specification relates to communications technologies, and in particular relates to an electronic tag information acquisition method and peripheral equipment. Background technique [0002] In practice, the user may wish to obtain information related to the peripheral device to match power supplies, fans and other peripherals such as peripherals production lot, manufacturer, date of manufacture. [0003] In the prior art, increasing the compliance-integrated circuit bus (Inter-Integrated Circuit in the peripheral, the I 2 Read Only Memory C) protocol, the ROM is stored in peripheral information, as an electronic tag peripherals. Specifically, the processor and peripherals connected by a connector, peripheral device from the read only memory will be mounted as the I 2 The C-bus, thus, the processor may by I 2 C-bus access to the memory device, determining information related peripherals peripherals. [0004] However, I 2 C-bus is a two wire bus sig...
