Conversion circuit of server PCIE signal and USB3.0 signal

Abstract

The invention relates to a conversion circuit of a server PCIE signal and a USB3.0 signal. The conversion circuit comprises a PCIE interface module, a conversion control chip and a USB3.0 interface module; a power pin of the conversion control chip is connected with a conversion control chip power supply circuit, and a power pin of the USB3.0 interface module is connected with a USB3.0 interface module power supply circuit; a server CPU transmits the processed running data through a PCIE port to the conversion control chip, the conversion control chip receives the data from the PCIE port in real time and achieves the switching between the PCIE signal and the USB3.0 signal through an internal conversion mechanism, and then the information is stored to a U drive or a mobile hard drive through a USB3.0 interface; otherwise, the server issues an address-searching command and searches for the address further to the external U drive or the mobile hard drive, and the conversion control chip reads the data in the external drive, converts into PCIE information and transmits the PCIE information to the CPU or a memory for server processing and handling.

Description

technical field [0001] The invention belongs to the technical field of server interfaces, and in particular relates to a conversion circuit for server PCIE signals and USB3.0 signals. Background technique [0002] PCI Express is a new generation of bus interface, which is a point-to-point serial device connection method, point-to-point means that each PCI Express device has its own independent data connection, and the concurrent data transmission between each device does not affect each other , and for the shared bus method of PCI in the past, only one device can communicate on the PCI bus. Once the number of devices connected to the PCI bus increases, the actual transmission rate of each device will decrease, and the performance cannot be guaranteed. PCI Express handles communication in a point-to-point manner. Each device establishes its own transmission channel when it requests to transmit data. This channel is closed to other devices. This operation ensures the exclusive...
