Description

Technical Field

[0001] The utility model relates to the technical field of motherboards, in particular to a Feiteng computer motherboard based on MXM. Background Art

[0002] With the continuous advancement of technology and the maturity of chip manufacturing technology and processes, domestic CPU chips are developing rapidly, among which Feiteng processors have higher performance. For example, the new eight-core processor Feiteng D2000 has a typical power consumption of 25W for a single CPU and a maximum main frequency of 2.3GHz. How to build a computer motherboard based on Feiteng D2000 with strong compatibility, maturity and stability is a technical problem that needs to be solved urgently. For example, in the existing technology, the SE_SMBUS of the connector is used as the host to read the interface of Feiteng D2000 in order to read the core temperature of the CPU. However, after the connector reads the core temperature, it cannot actively send the core temperature to the bottom layer to upload it. It is necessary to write a script on the system of the motherboard to upload the core temperature. This script is strongly related to the system. If the system is replaced, the script needs to be rewritten, which has poor compatibility. Utility Model Content

[0003] In view of the above technical problems, the present invention provides a Feiteng computer motherboard based on MXM to solve the problem of poor compatibility of Feiteng motherboards in the prior art.

[0004] Other features and advantages of the present invention will become apparent from the following detailed description, or may be learned in part from the practice of the present invention.

[0005] A Feiteng computer motherboard based on MXM includes a motherboard body, an MXM connector, and an MCU connected in sequence. In the port of the MXM connector, one or more expansion slots are led out to the motherboard body, and expansion signals are output to the motherboard body. The MCU has an I2CA interface and an I2CB interface, which are connected to the MXM connector and the I2C3 interface of the motherboard body through the I2CA interface and the I2CB interface respectively. When the MXM connector needs to read the CPU core temperature data of the motherboard body, the MXM connector triggers the MCU through the I2CA interface, and the MCU triggers the motherboard body through the I2CA interface and the I2C3 interface. After the motherboard body is triggered, it transmits the CPU core temperature data to the MCU through the I2C3 interface and the I2CB interface, and the MCU sends the CPU core temperature data to the MXM connector through the I2CA interface.

[0006] Furthermore, the expansion slot includes at least one of a PCIe x8 slot, a PCIe x4 slot, a PCIe x1 slot, an HDA audio interface, a GPIO, an HDMI, a USB3.0, a USB2.0, an SMBUS, and a UART.

[0007] Furthermore, the extended signal includes at least one of PWR_BTN#, RESET#, PS_ON#, and PWR_GOOD.

[0008] Furthermore, when the MCU sends the CPU core temperature data, it also saves a copy of the CPU core temperature data to a register.

[0009] The technical solution of the utility model has the following beneficial effects:

[0010] The rich interfaces based on the MXM connector greatly improve the compatibility of the Feiteng motherboard. The combination of MCU and connector solves the problem of needing to write scripts that are strongly associated with the system to read or upload the core temperature, thereby improving system compatibility.

The MCU3 has an I2CA interface and an I2CB interface, which are connected to the MXM connector 2 and the I2C3 interface of the motherboard body 1 through the I2CA interface and the I2CB interface respectively. When the MXM connector 2 needs to read the CPU core temperature data of the motherboard body 1, the MXM connector 2 triggers the MCU3 through the I2CA interface, and the MCU3 triggers the motherboard body 1 through the I2CA interface and the I2C3 interface. After the motherboard body 1 is triggered, the CPU core temperature data is transmitted to the MCU3 through the I2C3 interface and the I2CB interface. The MCU3 sends the CPU core temperature data to the MXM connector 2 through the I2CA interface, and when the MCU sends the CPU core temperature data, it also saves a copy of the CPU core temperature data to the register.
