Example Embodiment

[0019] Example 1:

[0020] Such as figure 1 As shown, an FPGA-based multi-channel KVM management board, the management board structure includes FPGA, MAX4312, MAX4310, MAX4023, where:

[0021] The line and field signals and I2C signals of the video in the KVM management board are all controlled by FPGA. The video channel is selected through FPGA, and it can support up to eight channels.

[0022] Since the VGA signal is an analog signal, and the FPGA can only process digital signals, the FPGA is connected to the MAX4312 for RGB gating, which can support up to eight options;

[0023] The strobed signal is input to MAX4310 for RGB cascade;

[0024] The cascaded RGB signal is input to MAX4023 for OSD video overlay;

[0025] The superimposed signal is output to the monitor for display.

[0026] Among them: the line and field signals are: HsyncXn_in and VsyncXn_in;

[0027] The I2C signals are: SCLXn_in and SDAXn_in. The I2C bus consists of a data line SDA and a clock signal line SCL to form a ...

Example Embodiment

[0028] Example 2:

[0029] On the basis of Embodiment 1, the FPGA described in this embodiment integrates the PS2 keyboard and mouse selector function, parsing and packaging function, and connects to an external MAX4999 for USB keyboard and mouse signal selection, which can support up to eight selections.

Example Embodiment

[0030] Example 3:

[0031] On the basis of Embodiment 2, the FPGA described in this embodiment integrates the USB MAC function of the USB part, and externally connects USB1T11A as the USBPHY and USBMAC functions to be implemented inside the FPGA.

Abstract

The invention discloses an FPGA-based multi-channel KVM management board which is characterized in that the management board comprises an FPGA, an MAX4312, an MAX4310, and an MAX4023; line and field signals and I2C signals of video in the KVM management board are controlled by the FPGA, and a video channel is selected by the FPGA; and the FPGA is externally connected with the MAX4312 for RGB gating, a gated signal is input to the MAX4310 for RGB cascading, a cascaded RGB signal is input to the MAX4023 for OSD video overlapping, and a superposed signal is output to a display for display. As chip use and cascade is reduced, the power consumption of the management board is greatly reduced, and the stability of the system is improved. The management board has the advantages of low power consumption, stable performance, convenient management, simple maintenance, and the like, and can be widely applied to KVM management systems of various servers.

Description

technical field [0001] The invention relates to the technical field of servers and KVM, in particular to an FPGA-based multi-channel KVM management board. Background technique [0002] KVM is an acronym for Keyboard, Video, and Mouse. The core idea of ​​KVM technology is: realize the centralized management of the system and network through the appropriate configuration of keyboard, mouse and monitor; improve the manageability of the system and improve the work efficiency of the system administrator; The total cost of ownership of the server system; avoid the radiation generated by the use of multiple monitors, and build a healthy and environmentally friendly computer room. Using the KVM multi-host switching system, system administrators can switch and manage multiple hosts or servers with different operating systems through a set of keyboards, mice, and monitors. [0003] FPGA (Field-Programmable GateArray), that is, field programmable gate array, is a product of further d...
