These modules, all users is used to customize the IP kernel of oneself.
The IP kernel of FPGA interior customizations can be together imported inside FPGA with configuration file.On at present most FPGA is
Chip on Dianbai chip, i.e. FPGA after electricity equivalent to a blank, could realize each only after configuration file is loaded with
Plant logic function.FPGA goes up every time electricity, is required for reloading configuration file, can thus make the core of protocol converter
(protocol conversion logical device) can be provided with different function and interface on every time during electricity.
As shown in Fig. 2 PHY chip 220 can include USB_PHY (PHY, Physical Layer, physics
Layer), (EtherCAT, Ether Control Automation Technology, Ethernet is automatically controlled EtherCAT_PHY
Technology), UART_PHY (UART, Universal Asynchronous Receiver/Transmitter, universal asynchronous receiving-transmitting

SPI packets；In the same manner, SPI protocol IP kernel receives parsing after SPI packets and obtains data content and pass to usb protocol IP
The data content for receiving is packaged into core, usb protocol IP kernel the usb data bag for meeting usb protocol.
When storage device for storing protocol conversion configuration file is differed, the class of corresponding configuration file interface 130
Type is also different, and for example, if storage device is SD card, corresponding configuration file interface is the draw-in groove of SD card；If storage device is
Micro SD cards, then corresponding configuration file interface is the draw-in groove of Micro SD cards.
It is alternatively possible to corresponding storage device storage area is set on the fuselage of protocol converter, for example, in Fig. 2
SD card storage area 250.In SD card storage area 250 multiple SD cards are placed equivalent to while carrying multiple corresponding point-to-point associations
View transducer；The volume of SD card is far smaller than the volume of protocol converter, therefore, the protocol converter that this utility model is provided is outstanding
It is easy to carry suitable for the various network system of fieldbus.
The course of work of protocol converter is introduced with reference to example：
User selects to be stored with according to the actual requirements the storage device of corresponding protocol conversion configuration file, for example, user
Need mutually to change PCIe protocol with PCI agreements, now select the storage of PCIe-PCI protocol conversion configuration files of being stored with

Logical resource module inside PCI protocol conversions configuration file configuration FPGA, and connect the logical resource module inside FPGA
Corresponding I/O interface is connect, the logical resource module inside the FPGA for having configured is to realize the main body of protocol conversion.
After having loaded PCIe-PCI protocol conversion configuration files, when the I/O interface of PCIe protocol receives PCIe data
Afterwards, transmit to FPGA through PCIe_PHY, FPGA calls PCIe protocol IP kernel parsing PCIe data to obtain specific data
Content is simultaneously stored in the depositor of FPGA；Then, FPGA calls PCI agreements IP kernel to seal the data content stored in depositor
The data for meeting PCI agreements are dressed up, through PCI_PHY I/O interface output corresponding to PCI agreements is transmitted, realize that PCIe data turns
Change the process of pci data into.
When user needs to carry out other kinds of protocol conversion, FPGA power down is first allowed, then, will be with configuration file interface
The storage device of 130 connections is replaced by the storage device of the protocol type the to be changed correspondence configuration file that is stored with.Re-power
The protocol conversion configuration file in storage device after afterwards FPGA loadings are changed, the process and said process after loading configuration file
Identical, here is omitted.
The protocol converter that the present embodiment is provided, using the FPGA of upper Dianbai chip as core, customizes in advance various associations
