Description
Technical Field
The present disclosure relates to an electronic card and a method for detecting the same, and more particularly, to an electronic card and a method for detecting the same, which can detect a communication protocol of a host and automatically execute a corresponding firmware unit according to the communication protocol of the host to execute the corresponding communication protocol.
Background
The standard specifications of the connector applied to the electronic card are mainly classified into Mini PCI-Express standard specification, mSATA standard specification, m.2 standard specification, and the like. The Mini PCI-Express standard connector is used to support PCIe communication protocol, the mSATA standard connector is used to support SATA communication protocol, and the m.2 standard connector (predecessor is Next Generation Form Factor (NGFF)) can support SATA, PCIe, and USB3.0 communication protocols. Since the connector conforming to the m.2 standard has multiple features of small size, power saving and fast transmission speed, and can simultaneously support the above three communication protocols, the electronic card using the connector conforming to the m.2 standard becomes the mainstream.
Although the connector under the m.2 standard specification can support SATA, PCIe and USB3.0 communication protocols at the same time, the host, such as motherboard, etc. connected to the electronic card and the electronic card only carries a single communication protocol, such as the host only carries SATA communication protocol, PCIe communication protocol or USB3.0 communication protocol, and the electronic card also only carries SATA communication protocol, PCIe communication protocol or USB3.0 communication protocol, and the user cannot easily know what the communication protocol carried by the host is, so when the host and the electronic card are to perform handshake (handshake) by using Out-of-Band (OOB) signals, if the communication protocols carried by the host and the electronic card are different, the packets cannot be exchanged correctly, and the communication between the host and the electronic card cannot be performed normally, so the user must continuously try to replace the electronic card carrying different communication protocols, so as to replace the correct electronic card conforming to the communication protocol of the host, and thus, the convenience of using the electronic card of the connector under the m.2 standard is not good. Furthermore, when the electronic card is handed over through the OOB signal, the electronic card using the connector under the m.2 standard only can start the internal communication protocol when the communication protocol carried by the electronic card is the same as the communication protocol carried by the host, and then correctly exchanges packets with the host, and the electronic card cannot automatically detect the communication protocol carried by the host when being connected to the host, and further selects the corresponding communication protocol, thereby increasing the inconvenience of the electronic card using the connector under the m.2 standard.
Therefore, how to develop an electronic card and a method for detecting the same that overcome the above-mentioned disadvantages is a urgent need.

It is to be understood that the disclosure is capable of various modifications in various embodiments without departing from the scope of the disclosure, and that the description and drawings are to be regarded as illustrative in nature, and not as restrictive.
Fig. 1 is a schematic structural diagram of an electronic card separated from a host according to a preferred embodiment of the present disclosure. As shown in fig. 1, the electronic card 1 of the present disclosure may be, but is not limited to, a Solid State Disk (SSD) or a non-volatile memory module, and is detachably assembled with a host 2, such as a slot on a motherboard, and when the electronic card 1 is assembled with the host 2, the host 2 may output an output signal to the electronic card 1 to communicate with the electronic card 1 for data transmission, where the electronic card 1 includes a connector 11, a first firmware unit 12, a second firmware unit 13, a third firmware unit 14, and a switch unit 15.

The first firmware unit 12 is used for executing the SATA communication protocol, so that the electronic card 1 and the host 2 can perform data transmission through the connector 11 by using the SATA communication protocol. The second firmware unit 13 and the third firmware unit are respectively configured to execute a PCIe communication protocol and a USB3.0 communication protocol, and respectively enable the electronic card 1 and the host 2 to perform data transmission through the connector 11 in a SATA communication protocol or a USB3.0 communication protocol.
The switch unit 15 is electrically connected to a plurality of terminals of the connector 11, wherein the switch unit 15 may be a microcontroller. The switch unit 15 can correspondingly execute the first firmware unit 12, the second firmware unit 13 or the third firmware unit 14 according to whether the communication protocol of the host 2 is the SATA communication protocol, the PCIe communication protocol or the USB3.0 communication protocol, and further execute the SATA communication protocol, the PCIe communication protocol or the USB3.0 communication protocol, so that the host 2 and the electronic card 1 perform data transmission under the same communication protocol.

Therefore, the electronic card 1 can perform data transmission under the same communication protocol as the host 2, and compared with the inconvenience caused by the prior art that the electronic card only supports a single communication protocol, the electronic card 1 of the present disclosure can automatically execute the corresponding firmware unit according to the communication protocol of the host 2 to execute the corresponding communication protocol, so that the convenience can be greatly improved.
It should be further noted that the connector 11 of the electronic card 1 may have different specifications (mainly distinguished by key positions, such as B-type, M-type, B + M-type, etc.) according to different communication protocols, and the definition of the terminals of the connector 11 is different under different specifications. For example, fig. 2 is a pin definition diagram of the connector conforming to the m.2 standard in the SATA communication protocol shown in fig. 1. As shown in fig. 2, when the electronic card 1 needs to communicate with the host 2 by the SATA communication protocol, the terminals numbered 41, 43, 47 and 49 of the plurality of terminals are defined to receive the output signal output by the host 2, so that the electronic card 1 communicates with the host 2 through the plurality of terminals numbered 41, 43, 47 and 49 to establish connection.

Fig. 4 is a pin definition diagram of the connector conforming to the m.2 standard in the USB3.0 communication protocol shown in fig. 1. As shown in fig. 4, when the electronic card 1 communicates with the host 2 according to the USB3.0 communication protocol, the terminals numbered 29, 31, 35 and 37 are defined to receive the output signal from the host 2, so that the electronic card 1 communicates with the host 2 through the terminals numbered 29, 31, 35 and 37 to establish connection.
In this embodiment, the terminals numbered 41, 43, 47 and 49 are differential signal groups (differential signal pairs) defined in the SATA communication protocol, the terminals numbered 41, 43, 47 and 49, the terminals numbered 29, 31, 35 and 37, the terminals numbered 17, 19, 23 and 25 or the terminals numbered 5, 7, 11 and 13 are differential signal groups defined in the PCIe communication protocol, the terminals numbered 29, 31, 35 and 37 are differential signal groups defined in the USB3.0 communication protocol, and the differential signal groups are used to receive output signals (i.e., differential signals) output by the host 2.
In addition, as can be seen from the above, the switch unit 15 of the electronic card 1 of the present disclosure can correspondingly execute the first firmware unit 12, the second firmware unit 13 or the third firmware unit 14 according to whether the communication protocol of the host 2 is the SATA communication protocol, the PCIe communication protocol or the USB3.0 communication protocol, and further execute the SATA communication protocol, the PCIe communication protocol or the USB3.0 communication protocol, so in order to determine whether the communication protocol of the host 2 is the SATA communication protocol, the PCIe communication protocol or the USB3.0 communication protocol, the switch unit 15 of the electronic card 1 of the present disclosure actually executes a detection method, which will be described below.
Referring to fig. 5 in conjunction with fig. 1, fig. 5 is a flowchart illustrating a detection method applied to the electronic card shown in fig. 1 according to a first preferred embodiment of the present disclosure. As shown in fig. 5, step M1 is executed to set an action set including a first action, a second action and a third action, wherein the first action is to detect whether there is an output signal at a plurality of terminals numbered 5, 7, 11 and 13 or at a plurality of terminals numbered 17, 19, 23 and 25 among the plurality of terminals of the connector 11, and when the detection result is yes, the communication protocol of the host 2 is judged to be the PCIe communication protocol, the second action is to detect whether output signals exist in a plurality of terminals with numbers 41, 43, 47 and 49, and continues to use the output signal to determine whether the communication protocol of the host 2 is the PCIe communication protocol or the SATA communication protocol if the detection result is yes, and the third action is to detect whether the output signals exist at the plurality of terminals of numbers 29, 31, 35 and 37, and continues to detect the output signal if the detection result is yes, so as to correspondingly determine the communication protocol of the host 2 as the PCIe communication protocol or the USB3.0 communication protocol according to the output signal.
Then, step M2 is executed to execute any one of the first action, the second action and the third action, and the detection method is terminated when the communication protocol of the host 2 is determined, otherwise, the next step is entered.
Then, step M3 is executed to execute any action in the action set except the action executed in step M2, and the detection method is terminated when the communication protocol of the host 2 is determined, otherwise, the next step is proceeded.
Finally, step M4 is executed, and the remaining actions in the action set except the actions executed in step M2 and step M3 are executed.
After the switch unit 15 finishes the above-mentioned detection method, the switch unit 15 can determine that the communication protocol of the host 2 is the SATA communication protocol, the PCIe communication protocol, or the USB3.0 communication protocol, and further, when the communication protocol of the host 2 is determined to be the SATA communication protocol, the first firmware unit 12 is executed to execute the SATA communication protocol, and when the communication protocol of the host 2 is determined to be the PCIe communication protocol, the second firmware unit 13 is executed to execute the PCIe communication protocol, and when the communication protocol of the host 2 is determined to be the USB3.0 communication protocol, the third firmware unit 14 is executed to execute the USB3.0 communication protocol.
In some embodiments, in the second action of the action set, when the output signals are detected to exist at the terminals 41, 43, 47 and 49, the output signals are continuously utilized to determine that the communication protocol of the host 2 is the PCIe communication protocol or the SATA communication protocol according to a predetermined determination condition, which may be, but is not limited to, setting to perform determination based on the differential pressure range of the output signals, for example, if the differential pressure range of the output signals is a to B, the communication protocol of the host 2 is determined to be the PCIe communication protocol, and if the differential pressure range of the output signals is detected to be C to D, the communication protocol of the host 2 is determined to be the SATA communication protocol. Furthermore, when the output signal is used and the communication protocol of the host 2 is determined to be the PCIe communication protocol or the SATA communication protocol according to the default determination condition, the detection method is terminated.
In some embodiments, the switch unit 15 of the electronic card 1 can directly determine that the communication protocol of the output signal of the host 2 is the SATA communication protocol or the PCIe communication protocol according to the definition of the Physical layer (Physical layer) for the signal, such as the voltage or the wavelength of the signal, so that in the second action, when the output signals are detected to exist at the terminals 41, 43, 47 and 49, the switch unit 15 continues to determine that the communication protocol of the output signal is the SATA communication protocol or the PCIe communication protocol according to the definition of the Physical layer, and thus, it can determine that the communication protocol of the host 2 is the PCIe communication protocol or the SATA communication protocol. Furthermore, when the switch unit 15 continues to determine that the communication protocol of the host 2 is the PCIe communication protocol or the SATA communication protocol according to the definition of the signal in the physical layer, the detection method is terminated. In addition, in the SATA communication protocol, the USB3.0 communication protocol, and the PCIe communication protocol, the definition of the signals by the physical layer has been defined, and is not described herein again.
In some embodiments, in the third action of the action set, when the output signals are detected to exist in the terminals 29 th, 31 th, 35 th and 37 th, the output signals are continuously utilized to determine that the communication protocol of the host 2 is the PCIe communication protocol or the USB3.0 communication protocol according to another predetermined determination condition, which may be, but not limited to, setting the pressure difference range of the output signals to be used for determination, for example, if the pressure difference range of the output signals is from a to B, the communication protocol of the host 2 is determined to be the PCIe communication protocol, and if the pressure difference range of the output signals is detected to be from E to F, the communication protocol of the host 2 is determined to be the USB3.0 communication protocol. Furthermore, when the output signal is used and the communication protocol of the host 2 is determined to be the PCIe communication protocol or the USB3.0 communication protocol according to the default determination condition, the detection method is terminated.
In some embodiments, the switch unit 15 of the electronic card 1 can directly determine that the communication protocol of the output signal of the host 2 is the PCIe communication protocol or the USB3.0 communication protocol according to the definition of the signal in the Physical layer (e.g., the voltage or the wavelength of the signal), so that in the third action, when the output signals are detected to exist in the terminals 29, 31, 35, and 37, the switch unit 15 continues to determine that the communication protocol of the output signal is the PCIe communication protocol or the USB3.0 communication protocol according to the definition of the signal in the Physical layer, so as to determine that the communication protocol of the host 2 is the PCIe communication protocol or the USB3.0 communication protocol. Furthermore, when the switch unit 15 continues to determine that the communication protocol of the host 2 is the PCIe communication protocol or the USB3.0 communication protocol according to the definition of the signal in the physical layer, the detection method is terminated. In addition, in the SATA communication protocol, the USB3.0 communication protocol, and the PCIe communication protocol, the definition of the signals by the physical layer has been defined, and is not described herein again.
Of course, another preferred embodiment of the present disclosure may perform the first action in step M2 shown in fig. 5, then perform the second action in step M3, and finally perform the third action in step M4. In other words, compared to fig. 5, which does not sequence the execution sequence of the first action, the second action, and the third action, the detection method of another preferred embodiment of the present disclosure is actually preset for the execution sequence of the first action, the second action, and the third action, and according to the sequence, the flowchart of the detection method of another preferred embodiment of the present disclosure will be shown in fig. 6 and will be described below.

Next, step S2 is executed, if the switch unit 15 detects that there is an output signal at the terminals numbered 17, 19, 23, and 25 or at the terminals numbered 5, 7, 11, and 13, the switch unit 15 determines that the communication protocol of the host 2 is the PCIe communication protocol and terminates the detection method, and if the switch unit 15 detects that there is no output signal at any of the terminals numbered 17, 19, 23, and 25 and the terminals numbered 5, 7, 11, and 13, step S3 is executed.
In step S3, the switch unit 15 detects whether there is an output signal at the terminals numbered 41, 43, 47, and 49 among the terminals.
Next, step S4 is executed, if the switch unit 15 detects that the output signals exist at the terminals numbered 41, 43, 47 and 49, the switch unit 15 uses the output signals to correspondingly determine that the communication protocol of the host 2 is the PCIe communication protocol or the SATA communication protocol, and if the output signals do not exist at the terminals numbered 41, 43, 47 and 49, step S5 is executed.
Next, step S5 is executed, and the switch unit 15 detects whether there is an output signal at the terminals numbered 29 th, 31 th, 35 th and 37 th among the terminals.
