Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0033] Please refer to figure 2 As shown, it is a schematic diagram of the structure of the present invention. The automatic detection device 220 of the present invention is electrically connected between the initiator device 210 (Initiator) and the target device 230 (Target). The initiating device 210 is the motherboard or HBA (host bus adapter) of the computer device, and the target device 230 can be but not limited to a backplane (backplane), and can also be other peripheral devices that support the interface protocol , In addition, the automatic detection device 220 can also be integrated in the target device 230 . Among them, the interface protocol includes SGPIO and I 2 C transport protocol.

[0034] The automatic detection device 220 includes an input interface 221 , an output inte...

Abstract

The invention discloses a device, a system and a method for automatically detecting an I2C (inter-integrated circuit) and an SGPIO (serious general-purpose input / output), which are applied to connect with different initiators, and can automatically switch the interface protocols of the targets of the initiators. The device comprises an input interface and a control unit. The input interface is connected with the initiator; the input interface further comprises a load pin, and the load pin is electrically connected with the load pin or a reset pin of the initiator; the control unit is connected with the input interface, and judges the interface protocol of the initiator according to the trigger signal which is received by the load pin; and the control unit stores the data signal from the initiator according to the corresponding interface protocol, and controls the light-emitting diode.

Description

technical field [0001] The present invention relates to a detection device, system and method thereof, especially to a kind of I 2 C and SGPIO automatic detection device, system and method thereof. Background technique [0002] With the miniaturization of integrated circuits and the rise of the Internet, the speed of data transmission and the capacity of storage devices have also increased. In order to quickly transfer a large amount of data between storage devices, a new type of serial technology is proposed to replace the traditional Small Computer System Interface (Small Computer Small Interface, SCSI) or high-tech configuration (Advanced Technology Attachment, ATA) The parallel interconnection technology of hard disks, while Serial SCSI (Serial Attached SCSI, SAS) and Serial ATA (Serial ATA, SATA) will formally replace the next-generation serial connection technologies of SCSI and ATA respectively. In order to display the operating status of SAS and SATA, general manuf...
