Abstract

The present invention relates to a USB interface control panel on-line update method, comprising steps of: the embedded soft-core processor, after receiving through USB module the on-line update command from the host computer, receiving update data sent from the host computer, and storing the update data into the volatile memory of the embedded soft-core processor; erasing the original embedded soft-core processor firmwares and/or FPGA configuration files stored in the non-volatile memory; writing the update data stored in the volatile memory into the non-volatile memory by means of programming. The present invention uses USB interface to realize the on-line updating of the control panel in the medical equipment and the like, wherein the control panel is capable of completely updating the embedded soft-core processor firmwares and/or FPGA hardware configuration files under the control of the host and without bringing interference to the normal operation by users.

Claims

1. A USB interface control panel on-line update method, comprising steps of:

A) an embedded soft-core processor, after receiving through a USB module an on-line update command from a host computer, obtaining update data sent from the host computer and storing the update data into a volatile memory of the embedded soft-core processor;

B) erasing the original embedded soft-core processor firmwares and/or FPGA configuration files stored in a non-volatile memory; and

C) writing the update data stored in the volatile memory into the non-volatile memory by means of programming.

2. The on-line update method of claim 1, wherein after performing the step C, a system used for the control panel enters into the normal operating state;

at this time, the system still executes the original embedded soft-core processor firmwares and/or FPGA configuration files.

3. The on-line update method of claim 1, wherein in performing the step B, the embedded soft-core processor firmwares and/or FPGA configuration files in the non-volatile memory are selectively erased according to different on-line update commands;

then the update data in the volatile memory is written into corresponding partitions of the non-volatile memory.

4. The on-line update method of claim 1, wherein prior to performing the step A, the system, after being powered on, loads the original FPGA configuration files into FPGA and loads the original embedded soft-core processor firmwares into the volatile memory, then starts to execute an application program, which has the on-line update function.

5. The on-line update method of claim 1, wherein after performing the step C, the host computer, through a USB interface in the USB module, sends a control panel reset command to reset the control panel, or the system is powered off and restarted, such that the system executes the updated embedded soft-core processor firmwares and/or FPGA configuration files.

6. The on-line update method of claim 1, wherein after performing said step C, the host computer, through the USB interface, sends a control panel reset command to reset the control panel, or the system is powered off and restarted, such that the system executes the updated embedded soft-core processor firmwares and/or FPGA configuration files.

7. The on-line update method of claim 3, wherein after performing the step C, the host computer, through a USB interface, sends a control panel reset command to reset the control pane, or the system is powered off and restarted, such that the system executes the updated embedded soft-core processor firmwares and/or FPGA configuration files.

8. The on-line update method of claim 4, wherein after performing the step C, the host computer, through a USB interface, sends a control panel reset command to reset the control panel, or the system is powered off and restarted, such that the system executes the updated embedded soft-core processor firmwares and/or FPGA configuration files.
