The most important is the audio decoding, the master chip will be the player in the compressed audio decompression. This is hardware decompression. There is also a thing called DAC, that is, a digital-to-analog converter, which converts the digital signal extracted from the third point above into an analog signal. Many MP3 player Dacs are not independent, but embedded in the main control chip.
Master control and audio decoding are two functions that have no relationship, but if the master control chip is integrated with the master control function and audio decoding function, so the master control chip is related to the sound quality. mp3 has three chips: master, audio chip, flashStorage, roughly corresponding to the computer cpu, sound card, memory. Some MP3s have two chips in them: the master and the flash. Audio decoding is integrated into the main control. This is the equivalent of an integrated sound card in a computer.
Master can't decide the sound quality SONY is NEC chips and some of its own chips, and SONY will never advertise what chip scheme is used, because SONY does not need to rely on this to promote. Even if SONY uses a nameless chip, the sound quality is more powerful than that of domestic MP3s that boast very high-end OOXX solutions. Ellie and sound quality have fallen, there is no need to discuss loveOdie uses telechips.
Error! The main control chip is also called DSP, that is, the digital signal processing main control chip has to deal with a lot of things: add and run the operating system (commonly known as firmware); Decode all kinds of files, such as TXT files, picture files, music files, etc., everything she can handle; The most important is the audio decoding, the main control chip in the player after the compressed audio to decompress. This is hardware decompression.
Hello, Meizu MP3mp3 master chip and audio processing chip '> About mp3 master chip and audio processing chip
Master control and audio decoding are two functions that have no relationship, but if the master control chip is integrated with the master control function and audio decoding function, so the master control chip is related to the sound quality. There are three chips in mp3: main control, audio chip, flash memory chip, roughly corresponding to the cpu in the computer, sound card, memory. Some MP3s have two chips in them: the master and the flash. Audio decoding is integrated into the main control. This is the equivalent of an integrated sound card in a computer.
Audio processing coreChip: The most concerned M6SL audio processing chip. (CODEC, rather than DAC as we usually call it, because most audio processing chips used by MP3 contain the functions of DAC and ADC at the same time, and provide some simple audio processing capabilities) It can be clearly seen that the M6SL adopts the WM8987 of Wolfson, Wolfson's series of chips with smooth and detailed high pitch, high resolution, and high quality. Known for low noise levels.
Master can't decide the sound quality SONY is NEC chips as well as some of its own chips, and SONY never advertised what chip scheme was used, because soNie doesn't need this to get publicity. Even if SONY uses a nameless chip, the sound quality is more powerful than that of domestic MP3s that boast very high-end OOXX solutions. Ellie and the sound quality have fallen, there is no need to discuss the love of Odie using telechips.
1, add to and run the operating system (commonly known as firmware); Decode all kinds of files, such as TXT files, picture files, music files, etc., everything she can handle; The most important thing isAudio decoding, the master chip decompresses the compressed audio in the player. This is hardware decompression. There is also a thing called DAC, that is, a digital-to-analog converter, which converts the digital signal extracted from the third point above into an analog signal.
2, there are three chips in mp3: master, audio chip, flash memory, roughly corresponding to the cpu in the computer, sound card, memory. Some MP3s have two chips in them: the master and the flash. Audio decoding is integrated into the main control. This is the equivalent of an integrated sound card in a computer. Flycore or Telchips are "integrated sound cards". They are the master control, but they also have the function of decoding audio.
3, ChipGenius is a USB device chip model query tool, also known as the chip wizard [3], it can automatically query the U disk, MP3/MP card reader, mobile hard disk and other master chip model, manufacturer, brand, and provide relevant information download address. Of course, you can also query the VID/PID information, device name, serial number, and device version of the USB device.
4, faster, safer, method with U disk MP3 master chip identification tool ChipGenius find outYour chip manufacturer, chip model, two parameters. Search online for the corresponding production software. Because there is no universal U disk mass production method, then search the Internet for the use of the corresponding mass production software. The next latest ChipGenius test shows that there are no chip manufacturers and chip model parameters, which should not be mass produced.
5, in general, you can take your mp3 firmware upgrade, the computer detection will appear your chip model, but not very accurate, you can be sure that you are using the manufacturer's decoding chip.
1, your equipment chip has been damaged, can not be used normally, can be sent to repair, can also be sent to the exclusive technical master, master remote operation. The specific operation is to prepare a windwos system computer, and conditional users can find a computer that is well configured and plugged with a network cable, which will effectively improve the efficiency of brushing and unlocking. Prepare a data line, and other brands on the market (millet OV) data lines can also be used (a data line that drags three is not acceptable).
2, if your computer can still recognizeTo your MP3, it may be relatively simple, analyze the reasons for the failure of the upgrade, and re-strictly follow the procedure to upgrade the operation once again can usually be solved.
3, Step 3: If the clock circuit is normal, the main control chip is not working well. Check the power supply of the main control chip. If the power supply is normal, the main control chip is damaged and can be replaced. In addition, there is another reason that the USB interface is insufficient power supply, which may be caused by too many peripheral devices connected to the USB interface. It is recommended to use a live USBHUB or a USB-to-PS /2 adapter.
4, this isIt's easy. Just get the firmware online, find a driver, and burn it.
5, execute the repair chip damage instruction. Step 8: Send instructions to repair the chip damage successfully, successfully repair the chip damage, the phone will automatically restart. 1) After the repair of the chip damage is completed and all operations are completed, the phone will automatically restart, and the first restart of the device will take about 5-10 minutes to wait for the boot. 2) After the phone restarts, activate the phone according to the system guidance. 3) Activate the phone according to the system guidance. 4) The desktop is successfully accessed, and the service ends.
