For details and implementations, please refer to the following figures and further description of the embodiments.

The first figure shows a first embodiment of a computer system for accessing audio data in an inactive state provided by the present invention. The computer system 10 of the present embodiment is powered by a power supply unit 100. The computer system 10 is exemplified by a portable computer such as a notebook, a small form factor mini-notebook (Netbook), or the like. The power supply unit 100 can be a battery or AC power source of the portable computer for supplying power required by the entire computer system 10 under various operating conditions. The operational state of computer system 10 includes an operational mode and a non-operation mode. The non-boot state referred to in this embodiment includes a sleep state (Hibernation, S4) and a shutdown state (Soft off) defined by a system power state according to an advanced configuration and power interface (ACPI) specification. , S5); The startup state refers to the state other than the sleep and shutdown states in the system power state.

The power supply unit 100 of the computer system 10 does not provide power only when the computer system 10 is in an activated state; unless the power supply unit 100 is completely separated or removed from the computer system 10, when the computer system 10 is in an inactive state, there is still Some system components operate in a sustainable part. For example, in a general computer system, an embedded controller (EC) continues to obtain the standby power of the power supply unit 100 and detects the power supply state of the computer system, but the first embodiment of the present invention The embedded controller is used as the state monitoring unit of the required computer system 10. It should be noted that the state monitoring unit in the first embodiment may also be any device in the computer system 10 that can detect the power supply state of the computer system 10. Those skilled in the art can replace the embedding with other devices according to actual needs. Controller.

The computer system 10 shown in the first figure includes: a state monitoring unit 102, an audio control module 104, a data switching unit 106, an audio output unit 108, a data access unit 110, a voltage voltage stabilizing unit 112, A logic operation module 120, and power switching units 122 and 124. The logic operation module 120 is a component of the computer system 10 that processes the logic operation, and includes a central processing unit 114, a logic controller 116, and a system memory 118. In addition, the audio control module 104 can be connected to the power supply unit 100 through the voltage voltage stabilizing unit 112.

As described above, since the state monitoring unit 102 continuously receives the power provided by the power supply unit 100, the state monitoring unit 102 can continuously monitor the power supply of the power supply unit 100 to the computer system 10, for example, monitor the output of the power supply unit 100. The magnitude of the current determines whether the state switching signal 102_S is asserted.

Therefore, when the state monitoring unit 102 determines that the computer system 10 is in a non-activated state, for example, when the current value output by the power supply unit 100 is lower than a predetermined threshold, the state monitoring unit 102 sets the state switching signal 102_S, and then the power is switched. The unit 124 will be closed according to the indication of the state switching signal 102_S, and the power switching unit 122 is turned on according to the indication of the state switching signal 102_S, so that the power supply unit 100 stops transmitting the voltage to the logic operation module 120. The operating voltage required by the audio control module 104 can be input to the audio control module 104.

In addition, the set state switching signal 102_S also controls the data switching unit 106 to output the audio data via the output end of the data access unit 110 (which becomes the output data 110_SO of the data access unit 110), and is transmitted by the link of the data switching unit 106. Finally, it is regarded as the input data 104_SI of the audio control module 104 and fed into the audio control module 104 for further processing. On the other hand, the set state switching signal 102_S also causes the audio control module 104 to transmit the processed audio data as the output data 104_SO to the data switching unit 106, and then to the audio output unit 108 as the audio output unit 108. The data 108_SI is input for the audio output unit 108 to play. For practical implementation, the audio output unit 108 of the embodiment can be further coupled to a device such as an earphone output, a speaker, or the like. In addition, the audio output unit 108 can also output a Bluetooth transmission module or a FM transmission module (FM) that transmits audio to the Bluetooth headset.

The audio control module 104 of the present embodiment can be a codec, such as an MP3 decoding module, which can read a storage unit (such as a hard disk) built in the computer system 10 or an external storage unit through the data bus (for example) USB external hard drive) stored audio data. Then, through a processor (such as a digital signal processor (DSP) or a microprocessor) built in the audio control module 104 and a converter (such as a DAC) and the like (not shown in the figure) , to compile, interpret or format conversion and other processing procedures. The above audio data may include a data format compatible with the MP3 decoding module, such as MP3, WAV, or WMA.

The data access unit 110 is, for example, a card reading device or a universal serial bus (USB) interface on the computer system 10, which can be connected to a storage unit, for example, to connect and read a memory card such as Flash, CF or SD by a card reading device ( Memory card), or an external hard disk that supports a USB interface with a USB interface. The data access unit 110 connects and reads one or more pieces of audio data stored in the storage unit for transmission to the audio control module 104 for processing. It should be noted that the audio control module 104 is activated when the computer system 10 is in the non-activated state, so that the audio control module 104 wants to read the hard disk or USB external connection of the computer system 10 through the data access unit 110. In the case of a device such as a hard disk, the audio control module 104 must add some drivers or software modules to become a master device to read the data in the slave device.

For example, the audio control module 104 must have an IDE/PATA/SATA driver or a software module built in to be an active device to read data in the hard disk. Similarly, the audio control module 104 must have a built-in USB driver. A program or software module can be used as an active device to read audio data from a USB external hard drive. Those skilled in the art can increase the driver program inside the audio control module 104 to read the required audio data according to actual needs. Furthermore, the computer system 10 can further include a control panel (not shown) having a plurality of operating units (such as a play button and a volume button). The user can control the operating units to generate control commands for controlling the audio control module. Group 104 performs the corresponding audio processing job.

On the other hand, when the computer system 10 is in the startup state, the state monitoring unit 102 detects that the current value currently supplied to the computer system 10 is higher than a predetermined threshold, the state monitoring unit 102 will de-assert the state switching signal 102_S. The power switching unit 122 is turned off according to the instruction of the canceled state switching signal 102_S, and the power switching unit 124 is turned on, so that the power supply unit 100 stops inputting the operating voltage to the audio control module 104, and the operating voltage is input into the logic operation. The module 120 is configured by the logic operation module 120 to execute various instructions of the computer system 10 in an activated state.

When the state switching signal 102_S is canceled, the data access unit 110 is also controlled to transmit the read data (ie, the output data 110_SO) to the input data 116_SI of the logic controller 116 via the data switching unit 106, and is coordinated by the logic controller 116. The other components of the logic operation module 120 are processed. In addition, the data switching unit 106 further transmits the audio data processed by the logic operation module 120 according to the canceled state switching signal 102_S: the output data 116_SO is sent through the logic controller 116, and then the data switching unit 106 uses the audio data as the audio output unit. The input data 108_SI of 108 is transmitted to the audio output unit 108, and the audio output unit 108 outputs the audio material.

The second figure depicts the internal structure of the data switching unit 106, which includes an audio input switching unit 1060 and an audio output switching unit 1062. The audio input switching unit 1060 includes a switch 10602 that switches according to an indication of the state switching signal 102_S output by the state monitoring unit 102. Since the state switching signal 102_S is set when the computer system 10 is in the non-activated state, it switches the control switch 10602 to the input of the audio control module 104, so that the output data 110_SO taken by the data access unit 110 will The input data 104_SI of the audio control module 104 is obtained.

In addition, the audio output switching unit 1062 includes a switch 10622, which is also controlled by the state switching signal 102_S, and switches to the output of the audio control module 104 when the computer system 10 is in the non-activated state to receive the audio control module. The audio output data 104_SO transmitted by the group 104 is then played back as the input data 108_SI transmitted to the audio output unit 108. It should be noted that in practical applications, a switch circuit can be provided on the motherboard of the computer system to construct the above-mentioned switch 10602 and 10622, so the manufacturing cost of the entire computer system does not increase too much, and the whole The system complexity is not too high.

When the state switching signal 102_S is canceled, the audio input switching unit 1060 switches the switch 10602 to the input of the logic controller 116 according to the control of the state switching signal 102_S, so that the output data 110_SO taken out by the data access unit 110 becomes logic. The input data 116_SI of the controller 116 facilitates the logic controller 116 to process the received data in conjunction with other components. Similarly, the audio output switching unit 1062 also switches the switch 10622 to the output end of the logic controller 116 according to the control of the state switching signal 102_S, so as to pass the audio data processed by the logic operation module 120 to the logic controller 116. (As the output data 116_SO of the logic controller 116) and the audio output switching unit 1062, the input data 108_SI of the audio output unit 108 is finally input and played.

It is to be noted that the audio control module 104 in the first embodiment can use the original data access unit 110 and the audio output unit 108 of the computer system 10 to enable the audio control module 104 through the switching of the data switching unit 106. When the computer system 10 is in a non-activated state, the audio data can be received and the audio data can be output. The computer system 10 does not need to provide additional system components for inputting or outputting audio data in a non-activated state, and does not increase the manufacturing cost of the computer system 10 while increasing the use value of the computer system 10.

As for the actual implementation of the state switching signal 102_S, one of the pin inputs of the general-purpose input/output (GPIO) of the embedded controller can be connected to the audio control module 104, and a high-potential signal is sent through the general-purpose output pin. The audio control module 104 is provided to notify the audio control module 104 and initiate subsequent audio processing operations. Therefore, the state switching signal 102_S can be switched when the state monitoring unit 102 detects that the computer system 10 is in the startup state (for example, when the current value is higher than a predetermined threshold), and then cancels the setting state switching signal 102_S ( For example, when the state monitoring unit 102 detects that the computer system 10 is in a non-activated state (for example, when the current value is lower than a predetermined threshold), the state switching signal can be The potential value of 102_S is switched to a low potential.

The third figure depicts a power switching state diagram of the first embodiment of the present invention. When the set state switching signal 102_S turns off the power switching unit 124, so that the audio control module 104 starts to obtain the required operating voltage, the power switching unit 122 is turned on at the same time, so that the logic computing module 120 is turned off. power supply. In addition, since the data switching unit 106, the audio output unit 108, and the data access unit 110 in the present invention need to operate regardless of whether the computer system 10 is in the activated state or the non-activated state, the power supply unit 100 The operating voltages required by them will continue to be provided without being affected by the state of the state switching signal 102_S (ie, being set or not).

It should be noted that the operating voltages of the units of the computer system 10 are not necessarily the same, and the power state diagrams depicted in the third diagram are simplified for convenience of explanation. Those skilled in the art should be aware that in actual implementation, The operating voltage required by the unit is used for circuit layout.

It should be noted that when the computer system 10 enters the startup state, other system components (such as the network control unit, the logic operation module 120, etc.) other than the audio control module 104 of the computer system 10 are received by the power supply unit 100. electric power. If the user wants to play the audio data in the activated state, the computer system 10 will use the central processing unit 114 to control the audio file stored in the hard disk through the control of the logic controller 116 (such as the south and north bridge chips). The network control unit accesses the audio file of the Internet, converts the file, encodes and decodes the file, and outputs the file to the audio output unit 108.

In the startup state, the computer system 10 must supply operating voltages to various system components, so that the central processing unit 114 performs data processing, hard disk rotation and reading, control of the light signals, and the like, so as to provide the user with the computer system 10 at any time. Archive editing, surfing the Internet, drawing, or watching movies. It can be seen that all components except the audio control module 104 must enter the startup state, that is, the computer system 10 must not be in the non-activated state; therefore, the power consumption is large in the startup state, so that it is obviously impossible to achieve the province. The effect of electricity.

In the case of a general notebook computer, the continuous power supply time of the power supply unit 100 in the activated state is on average only about six to eight hours. However, according to the habits of many users, the computer system 10 is often fully activated and consumes a large amount of power, but it is not a complicated operation, but only a simple operation such as listening to music or songs (in other words, only as music). For the purpose of the player, at this time, by means of the method provided in this embodiment, the audio control module 104 capable of independently processing data can be activated in the state where the computer system 10 is turned off or in standby, and the audio data cannot be played or The missing unit plays the audio file, and the audio data will be turned off when the audio data is not used (for example, no power is supplied to them), which not only eliminates the user's troublesome program, but also does not need to supply power. Other system components (such as network control unit, logic operation module 120, etc.) that have no work to be processed can achieve power saving requirements. With the means proposed in this embodiment, the same power supply unit 100 can cause the audio control module 104 to operate for a longer period of time.

The audio control module 104 in the embodiment receives the power, and directly connects the audio control module 104 to the power supply unit 100. However, the voltage voltage stabilization unit 112 can be disposed between the power supply unit 100. The output voltage is reduced to be suitable for the operating voltage of the audio control module 104; or the standby power source (Standby power) is directly used as the power source, and is sufficient to support the voltage required for the operation of the audio control module 104.

In addition, the user can control the output of the audio output unit 108 by remote control, in addition to operating the control panel (not shown) to input control commands to the audio control module 104. For example, the state monitoring unit 102 of the present embodiment may include an infrared receiving module 1020 (as shown in the first figure), so that the user can send a control command through a remote control device (ie, a remote controller), and the infrared receiving module is received by the infrared receiving module. After the group 1020 is received, the status monitoring unit 102 transmits the control command received by the infrared receiving module 1020 to the audio control module 104. In the actual implementation, the embedded controller can also be used to achieve the above remote control, because the embedded controller contains a consumer infrared (CIR) module, which is used in the remote control mechanism of the electronic product. Among them. It should be noted that any module that can be built in the status monitoring unit 102 to respond to the remote control and initiate the related operations in the non-activated state can be applied to the present embodiment.

The fourth figure is a block diagram of a second embodiment of a computer system for accessing audio data in a non-activated state according to the present invention. The second embodiment is different from the first embodiment in that the computer system 10a is provided with a data access unit 110a directly connected to the audio control module 104a, and the audio control module 104a is further provided with a data access interface. 1040. In this embodiment, the data access unit 110a and the data access interface 1040 switch through the audio control switching unit 126 to determine whether to input audio data to the audio control module 104a, so that the audio control module 104a does not need to share the computer system 10a. Some data access units (such as 110 shown in the first figure). In another embodiment, the data access unit 110a may be directly connected to the audio control module 104a without setting the audio control switching unit 126.

Specifically, since the computer system 10a usually has more than one data access unit, for example, the computer system 10a is provided with a plurality of USB interfaces or a plurality of card reading devices, and those skilled in the art can visually design and manufacture the computer system 10a. The requirement is to dedicate one of the interfaces or one of the card reading devices to the input data to the audio control module 104a. Of course, the remaining USB interface or card reading device can still be used by the computer system 10a to access data in the startup state.

In the second embodiment, the audio control switching unit 126 disposed between the data access interface 1040 and the data access unit 110a is also controlled by the state switching signal 102_S. When the state switching signal 102_S is set, the data access unit is turned off. The audio data outputted by 110a (ie, the output data 110_SO) is transmitted to the data access interface 1040 via the audio control switching unit 126 as the input data 104_SI of the audio control module 104a. Therefore, the audio control module 104a directly connects to the dedicated card reading device (ie, the data access unit 110a), and directly accesses the data of the user's data access unit 110a through the storage device access interface 1040. Under such a design, the data switching unit 106a does not need to further include an audio input switching unit (such as 1060 in the second figure), and also eliminates data switching processing between the audio control module 104a and the logic controller 116, and manufactures It's easier.

In addition to reading audio data or files from the data access unit 110a in the non-activated state, when the computer system 10a is in the startup state, the audio data can still be accessed or updated through other components, such as by the logic operation module 120. Controlling the reading of data in the hard disk, or accessing the audio file on the Internet through a network control unit (such as a network interface card), and then inputting it to the audio output unit 108 for playing. The setting of the computer system 10a for processing the audio material in the non-activated state does not affect the normal operation in the startup state.

In addition, even if the computer system 10a is in a non-activated state, the user does not necessarily want the audio control module 104a to perform operations for processing and outputting audio data. Therefore, the computer system 10a of the second embodiment may include connection to the audio control. The control button 128 of the module 104a, and the user can use the control button 128 to control whether the audio control module 104a starts to operate or not.

When the computer system 10a is in the non-activated state, the audio control module 104a has obtained the power supplied by the power supply unit 100, but before the user presses the control button 128 to activate the audio control module 104a, the audio control module 104a The data access unit 110a is not accessed or the audio data is read, and only the standby power supply is used to continuously detect the pressing of the control button 128 (ie, the closed or open state). Until the control button 128 is pressed, on behalf of the user wishing to listen to the audio data processed and output by the audio control module 104a on the audio output unit 108, the audio control module 104a activates the control button 104 according to the pressing of the control button 128. The job of processing audio data.

For the connection and function between other components in the second embodiment, please refer to the description of the first embodiment.

The fifth figure is a flowchart of an embodiment of a method for accessing audio data in a non-activated state by a computer system according to the present invention, and please refer to the first figure at the same time. In this embodiment, the computer system 10 continues to use the status monitoring unit 102 to detect whether the operating state of the computer system 10 is in an activated state or a non-activated state (S301). When the computer system 10 is in the non-activated state, the status monitoring unit 102 sets the status switching signal 102_S to notify the audio control module 104 to start receiving its required operating voltage from the power supply unit 100 (S303). On the other hand, if the computer system 10 is in the startup state, the state monitoring unit 102 will cancel the setting state switching signal 102_S to notify the audio control module 104 to stop receiving the operating voltage (S315).

After obtaining the voltage required for the operation, the audio control module 104 can be activated according to the user pressing the control button 128 (refer to the fourth figure), and starts to read the audio data from the data access unit 110 (S305); The control command input by the control panel or the remote control device may be further received (S307), for example, playing or stopping the playing of the audio data; and then the corresponding processing is performed on the audio data according to the received control command (S309). For example, the audio data in the example is: song or music; and the processed audio data is transmitted from the audio control module 104 to the audio output unit 108 via the transmission of the data switching unit 106 controlled by the state switching signal 102_S (S311).

In the above process, even if the computer system 10 is in the non-activated state, the state monitoring unit 102 still detects the power supply condition of the power supply unit 100, and therefore, the state monitoring unit 102 continuously determines whether the operating state of the computer system 10 has changed ( S313), here, it is judged whether the computer system 10 has entered the startup state. If the operating state of the computer system 10 has not changed, the audio control module 104 can return to step S309 and continue to perform operations for processing audio data and output, such as playing, pausing, or fast-forwarding music. However, if in step S313, the state monitoring unit 102 determines that the computer system 10 enters the startup state according to the change of the power supply state of the power supply unit 100 (for example, the current is higher than a predetermined threshold), according to the startup of the computer system 10 The status performs the following procedure.

After detecting and judging in step S301 or step S313, after the computer system 10 enters the startup state, the state monitoring unit 102 cancels the setting state switching signal 102_S, thereby notifying the audio control module 104 to stop receiving the power supply unit 100. Operating voltage (S315); and then other system components (such as logic computing module 120, hard disk, network control unit, etc.) in computer system 10 obtain power from power supply unit 100 (S317), thereby causing the computer system 10 can be operated and processed by the central processing unit 114 and the logic controller 116 of the logic operation module 120 (S319) to provide various service functions provided by the general computer device; at this time, the data switching unit 106 switches the audio. The connection path of the output unit 108 is such that the audio output unit 108 is connected to the data output end of the logic controller 116 to send the data to be played (ie, the output data 116_S0) to the audio output unit 108 (ie, the input data 108_SI) as an output. For sound files such as music or songs.

As in step S313, the state monitoring unit 102 continues to determine whether the computer system 10 changes from the startup state to the non-boot state according to the power supply state of the power supply unit 100 (S321): if the startup state is unchanged, the computer system 10 continues to be logically operated. The components such as the module 120 provide services (S319); and when the computer system 10 is turned off or in the standby state, the steps S303 and the following are executed again. Thereby, in order to achieve the general operation of the computer system 10 in the startup state, the effect of reading and processing the audio data can be provided and outputted in the non-activated state.

Therefore, combining the above-described illustrated contents and drawings, it can be seen that the computer system and the method for accessing audio data provided by the present invention can be used in cooperation with the original system device of the computer system. Taking the example illustrated in the above embodiment as an example, the embedded controller only needs to use one general-purpose input pin to implement the transmission of the switching signal, and the card reading device can read the audio file in the memory card and the audio output unit. It is a necessary component in a general computer system; computer system producers do not need to greatly adjust the computer system architecture in order to provide audio services when they are not turned on, thereby avoiding an increase in cost.

In addition, after the power is turned off, the original power supply unit is used for power supply. Even if the mechanism for providing audio data access is provided, it is not necessary to separately configure an external power supply or a backup power supply auxiliary power supply unit to avoid the manufacturing cost of the computer system or the increase in the size of the device. In the non-activated state, the power supply unit only needs to provide the power needed to process and play the audio data, which saves a lot of time compared to the traditional way of making the entire computer system fully operational.

In addition, the method of providing audio data control in the non-activated state is also in line with the general user's preference for listening to music or songs for a long time, combining the advantages of low production cost and power saving; taking a portable computer as an example, using The computer system that can access the audio data can access the audio file at any time outdoors, thereby increasing the convenience of use and improving the use value of the computer system.

However, the items and elements of the above-described embodiments are merely illustrative of the invention and are not intended to limit the scope of the claimed invention. It is also within the scope of the present invention to modify or modify the micro-frames in accordance with the spirit of the present invention and the technical means disclosed herein.
