drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive labor.

Fig. 1 is a system block diagram of the present control board.

Detailed Description

the present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

The first embodiment is as follows:

A control board card for SRIO and USB conversion comprises an SOC chip, an SRIO controller, an SRIO interconnection controller and a USB control module;

The SOC chip adopts ZYNQ series chips of XILINX, the series of processors can be expanded to 4 cores according to the PS end, and the SOC chip internally adopts AXI4 bus to interconnect the PS end and the PL end;

The USB control module comprises a USB controller and a USB PHY chip, the USB controller adopts a USB3.0 controller, and the USB3.0 controller adopts a CYUSB3014 chip;

The PL end of the SOC chip is connected with the SRIO interconnection controller through the SRIO controller, the PL end of the SOC chip is connected with the DDR4 for controlling reading and writing, and the SOC chip is connected with the USB PHY chip through the USB controller;

Before using the novel control board card, a worker connects the SRIO interface of the SRIO interconnection controller with the SRIO equipment of the system, the worker connects the USB PHY chip with the USB storage,

when the novel control board card works, the PS end of the SOC chip is used for monitoring the state of a system, managing the temperature and expansion, the PL end of the SOC chip, the SRIO interconnection controller selects transmission data of SRIO equipment of the system, the selected SRIO message data are transmitted into the SRIO controller, the SRIO controller analyzes the data message according to an SRIO protocol, the PL end of the SOC chip extracts the analyzed data in the SRIO controller, then the SOC chip stores the analyzed data in the DDR4 according to control information of the PS end, the data in the DDR4 enters the USB3.0 controller through logic control of the PL end of the SOC chip, the USB3.0 controller packs the data into a USB data packet according to the USB protocol, and the USB data packet is moved into the USB storage after signal conversion of the USB PHY chip; when data enters the system from the USB storage, the inverse process of the above process is adopted, thereby realizing the data bandwidth balance conversion, avoiding the data loss in the conversion process and simultaneously improving the data conversion speed between the SRIO and the USB.

Example two:

on the basis of the first embodiment, when the USB storage is multiple, the number of the USB control modules corresponds to the number of the USB storage one by one, the PS terminal of the SOC chip can store the ID number stored by the USB in the register in the SOC chip, and the PL terminal selects the data path through the arbiter in the SOC chip according to the ID number, so that the method is suitable for the conversion work between the SRIO and the multiple USB storage mobile devices.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
