Specifically, owing to although the first expansion bus interface 112 of similar thunderbolt interface controller etc has transfer rate faster, but its design is also comparatively high with manufacturing cost, if transmission usefulness and also use transfer rate the first expansion bus interface 112 faster at the second expanding device 120_1 and 120_2, then the price of enlargement module 100 will be difficult to reduce and the market competitiveness is declined.
Additionally, for the ancillary equipment such as general card reader or CD drive, utilize USB interface can be transmitted normally making electronic apparatus use its extended function.In other words, owing to the volume of transmitted data of general ancillary equipment is relatively low, if provide transfer rate expansion bus interface faster, for general ancillary equipment zero difference.
In order to make enlargement module 100 be utilized respectively to have the expansion bus interface of different transmission rates to control different types of ancillary equipment, to provide expansion bus interface faster for the ancillary equipment with higher transmission demand.Therefore, in the first expanding device 110, the signal passed through mutually is changed by the first expansion bus interface 112 and the second expansion bus interface 114 between the first expansion bus standard Ptl_1 and the three expansion bus standard Ptl_3, make the first ancillary equipment 116 and the second ancillary equipment 124_1 and 124_2 can be utilized respectively the signal meeting the first expansion bus standard Ptl_1 and the second expansion bus standard Ptl_1 to be transmitted, to provide extended function to use to electronic apparatus 10.
For example, electronic apparatus 10 can carry out signal exchange by the first expansion bus interface 112 by transfer rate the first expansion bus standard Ptl_1 faster and the first ancillary equipment 116, to make electronic apparatus 10 use the extended function of the first ancillary equipment 116.And, for general ancillary equipment, such as the second ancillary equipment 124_1 and 124_2 etc., the then signal conversion between the first expansion bus standard Ptl_1 and the three expansion bus standard Ptl_3 by the first expansion bus interface 112 and the second expansion bus interface 114, and carry out signal exchange by the 3rd expansion bus standard Ptl_3 and the second ancillary equipment 124_1 and 124_2, to make electronic apparatus 10 use the extended function of the second ancillary equipment 124_1 and 124_2.Wherein, first ancillary equipment 116 such as has the ancillary equipment of higher transmission demand for Graphics Processing Unit (GPU:GraphicsProcessingUnit) or video card (Videocard) etc., each second ancillary equipment 124_1 and 124_2 is such as then Hard Disk Drive (harddiskdrive, be called for short HDD), CD drive (opticaldiskdrive, it is called for short ODD) or the ancillary equipment of card reader etc., the present invention is not limited.
In addition, although the present embodiment being include an ancillary equipment respectively for the first expanding device 110 and the second expanding device 120_1 and 120_2, but in other embodiments, first expanding device and each second expanding device all can include multiple ancillary equipment to provide electronic apparatus to use, and the present invention is also not limited.
Fig. 2 is the schematic diagram of the enlargement module of another embodiment of the present invention.In the present embodiment, enlargement module 200 includes the first expanding device 210 and at least one the second expanding device, at this for the second expanding device 220_1 and 220_2.
Refer to Fig. 2, in the present embodiment, the second expanding device 220_1 also includes the 4th expansion bus interface 226_1 and at least one the 3rd ancillary equipment, at this for the 3rd ancillary equipment 228_1.Similarly, the second expanding device 220_2 then also includes the 4th expansion bus interface 226_2 and at least one the 3rd expanding device, at this for the 3rd ancillary equipment 228_2.
3rd ancillary equipment 228_1 and 228_2 is respectively coupled to the 4th expansion bus interface 226_1 and 226_2, and the 4th expansion bus interface 226_1 and 226_2 couples universal input output (GPIO:generalpurposeinput/output) port GPIO of the first expansion bus interface 212 of the first expanding device 210.Wherein, the first expansion bus interface 212 provides the 3rd ancillary equipment 228_1 and 228_2 to use for electronic apparatus 10 by the 4th expansion bus interface 226_1 and 226_2 respectively.
Specifically, in the present embodiment, in order to further increase the function of enlargement module 200, and it is compatible with the 3rd original expansion bus standard Ptl_3, therefore employ the part circuit of the 3rd original expansion bus standard between the 4th expansion bus interface 226_1 and 226_2 and the first expansion bus interface 212 in each second expanding device 220_1 and 220_2 to exchange signal, and the signal transmission between the second expansion bus interface 214 and the 3rd expansion bus interface 222_1 and 222_2 does not use this part circuit.So the part circuit that the 4th expansion bus 226_1 and 226_2 uses does not affect the signal transmission of the 3rd expansion bus standard Ptl_3, the 3rd expansion bus interface 222_1 and 222_2 and the second expansion bus interface 214 still can carry out signal exchange by the 3rd expansion bus standard Ptl_3.In other words, now the circuit not used by the 4th expansion bus interface 226_1 and 226_2 is used to be transmitted between the second expansion bus interface 214 and the 3rd expansion bus interface 222_1 and 222_2.
In addition, owing to the part circuit merely with the 3rd expansion bus standard carrys out the transmission line as the 4th expansion bus interface 226_1 and 226_2, not increasing additional wires, therefore the first expanding device 210 and the second expanding device 220_1 and 220_2 still can pass through to meet joint P1 and the P2 of the 3rd expansion bus standard Ptl_3 and be mutually coupled.
First expansion bus interface 212 is using a universal input and output port GPIO as the bridge joint (Bridge) between the 4th expansion bus interface 226_1 and 226_2 and electronic apparatus 10.Therefore, electronic apparatus 10 can individually by the universal input and output port GPIO and each the 4th expansion bus interface 226_1 and 226_2 of the first expansion bus interface 212 exchange signal, and so that by the extended function of the 3rd ancillary equipment 228_1 and 228_2.
Accordingly, the present embodiment can not change joint P1 and P2, only realizes utilizing signal transmission standard two kinds different to control to use the application of different types of ancillary equipment in same second expanding device 220_1 and 220_2 in the way of utilizing the part circuit of the 3rd expansion bus standard Ptl_3.
In general USB standard, it is utilized respectively power line, a plurality of data lines and earth lead to transmit signal.But in the present embodiment, owing to the second expanding device 220_1 and 220_2 has independent power supply input, therefore it does not need to provide power supply by electronic apparatus 10, therefore, when utilizing the 3rd expansion bus standard Ptl_3 to carry out the signal exchange between the second expansion bus 214 and the 3rd expansion bus 222_1 and 222_2, its power line can be considered the circuit not affecting signal transmission.Therefore, it is utilize the 3rd expansion bus standard Ptl_3 uniline therein (that is power line of USB) to make and between the first expansion bus interface 212 and the 4th expansion bus interface 226_1 and 226_2, use single line communication standard (one-wireprotocol) to exchange signal at above-mentioned uniline in the present embodiment.
So-called single line communication standard, refers to the data and signal transmission that utilize an independent wire to carry out between two electronic installations.Therefore, the 3rd ancillary equipment 228_1 and 228_2 can be fairly simple ancillary equipment.4th expansion bus interface 226_1 and 226_2 can provide the 3rd ancillary equipment 228_1 and 228_2 to use for electronic apparatus 10 by single line communication standard on the power line of the 3rd expansion bus standard Ptl_3.
On the other hand, in the first expanding device 210, the first expansion bus interface 212 couples the power line of the 3rd expansion bus standard Ptl_3 by its universal input and output port GPIO, meets the signal of single wire transmission standard with transmission.In addition, first expansion bus interface 212 also changes received signal, and utilize the second expansion bus standard Ptl_2 and the second expansion bus interface 214 to exchange signal, and the second expansion bus 214 couples data wire and the earth lead of the 3rd expansion bus 222_1 and 222_2, to utilize the 3rd expansion bus standard Ptl_3 and the three expansion bus interface 222_1 and 222_2 to exchange signal, and electronic apparatus 10 is made to use the second ancillary equipment 224_1 and 224_2 and the extended function of the 3rd ancillary equipment 228_1 and 228_2 according to this.
In actual application, the 3rd ancillary equipment 228_1 and 228_2 can include transmission suggestion device ALD1 and the ALD2 pointing out the connection status of enlargement module 200 respectively.
For example, when as the second expanding device 220_1 and 220_2, one of them carries out signal transmission with electronic apparatus 10, electronic apparatus 10 can control the transmission suggestion device (ALD1 or ALD2) of this second expanding device (220_1 or 220_2) and send transmission prompting to point out user electronic apparatus 10 controlling this second expanding device.Wherein, the transmission prompting that transmission suggestion device ALD1 or ALD2 sends can be bright light, send the transmission prompting of prompt tone or voice etc., remind user the second expanding device 220_1 or 220_2 transmitting signal of interest or data, cause error of transmission or careless mistake to avoid user to pull out the second expanding device at this moment.
Above-mentioned signal transmission can occur when electronic apparatus 10 reads data from second ancillary equipment 224_1 or 224_2 of the second expanding device 220_1 or 220_2, or electronic apparatus 10 is when writing data to the second ancillary equipment 224_1 or 224_2 of the second expanding device 220_1 or 220_2, electronic apparatus 10 after above-mentioned reading data or write data complete, can control transmission suggestion device ALD1 or ALD2 and stop sending transmission prompting.When transmitting suggestion device ALD1 and ALD2 and stopping sending transmission prompting, namely represent user and now can pull out the second expanding device.
Above-mentioned signal transmission also can occur when the second expanding device is disabled action by electronic apparatus 10, for instance USB (universal serial bus) disable action.When electronic apparatus 10 is transmitting in the process of data, user also can by directly controlling the second expanding device 220_1 or 220_2 that the data transmission of transmission suggestion device ALD1 or ALD2 the second expanding device stopping specifying is specified to choose.
Specifically, when the transmission suggestion device of the second expanding device specified receive that user assigns when pulling out instruction, electronic apparatus 10 according to pulling out the instruction the second expanding device to specifying and can couple the order the second expanding device after the second expanding device specified and disables action, to stop the second expanding device specified and the data transmission coupling the order the second expanding device after the second expanding device specified.Above-mentioned disable action can include by the data not yet write write above-mentioned the second expanding device being about to disable.Electronic apparatus 10 can disable after action completes above-mentioned, controls transmission suggestion device ALD1 or ALD2 and stops sending transmission prompting.
For example, when the transmission suggestion device ALD_1 of the second expanding device 220_1 receives and pulls out instruction, electronic apparatus 10 according to pull out instruction and to the second expanding device 220_1 and couple the order the second expanding device 220_2 after the second expanding device 220_1 and disable action.When the transmission suggestion device ALD2 of the second expanding device 220_2 receives and pulls out instruction, electronic apparatus 10 is then according to pulling out instruction and only the second expanding device 220_2 being disabled action.Wherein, transmission suggestion device ALD1 or ALD2 is assigned the mode pulling out instruction and can be realized by control knob by user, pulls out instruction to be specified by pressing the button on the second expanding device to assign, but the present invention is not limited.
