For Mobile App —How to Use the TAS2560 on Qualcomm Platforms

With the popular trend of thin and light smartphone products, the size of the speaker is becoming more and more limited, which causes the performance of the external playback to be difficult to improve. At the same time, audio is now a very important selling point for cell phones, and loud volume and good sound quality are very mainstream requirements in the market. So in the face of these two aspects of a Tradeoff, SmartPA in the market demand more and more.

SmartPA is mainly through the intelligent protection algorithm to achieve the protection of the speaker amplitude and speaker temperature, so as to give full play to the potential of the speaker, in the case of limited speaker space to achieve loud volume and good sound quality. This part of TI's solutions mainly include TAS2557, TAS2560 and TAS2559. for mono program, mainly built-in DSP TAS2557 and TAS2560 without DSP. for the built-in DSP program, the protection algorithm is running on the chip's internal DSP, so the realization of a relatively easier. That for the program without DSP, the protection algorithm is required to run on the platform side of the DSP, that this article is mainly for this application, introduced under the TAS2560 how to use the Qualcomm platform.

Step 1. Confirm the actual needs of the project, mainly including the following points:

• Is the project mono or stereo?
• How many bits is I2S? What is the specific format?
• What is the maximum sample rate? Generally 48K or 44.1K.
• Confirm the storage location of the algorithm related parameters, is it directly using the bin file or using Qualcomm's default acdb file?
• For SmartPA usage, how many usage scenarios are required?
• Requirements for factory calibration: Is there a standard test flow and test sound source? Are there any other requirements besides Re calibration?

Step 2. Focuses on the integration of the TAS2560 driver

This part of the TI to provide standard reference code, the implementation is relatively easy, the goal is to achieve the Speaker's normal sound. At this stage, you can directly do some tests on some electrical characteristics, such as THD + N, bottom noise, etc. to confirm whether the audio path is normal. The following points should be noted:

Confirm the format of the platform's output I2S signal, preferably reconfirmed by an oscilloscope.

Pay attention to the setting of PLL on the side of TAS2560, if there is noise problem, it is recommended to confirm whether the PLL is correct first.

Inside the driver you need to know the range of DC impedance values of the speaker.

Step3. The algorithm in the Qualcomm platform porting, the main work, as shown in the figure below, is to integrate the algorithm library of our smart amplifier and the corresponding Framework into the ADSP side of the Qualcomm platform, generally speaking, the ADSP is directly integrated into the main platform. The detailed steps are shown below:

Enable the TX port of I2S on the platform side. The TX path is the path fed back from the TAS2560 to the platform.

Confirm that the feedback IV signal is correct.

DSP side and AP side related code implementation, this part is also related to the reference code for reference.

PPC3 installation, and ensure that the PPC3 and cell phone side of the communication is normal. PPC3 is a professional graphical interface tool provided by TI.

Factory calibration code implementation, pay special attention to the need to do calibration in the time to close the audio path on the algorithm.

Algorithm verification, this part of TI will also provide a standard verification process.

Step4.  Modeling and tuning, this part mainly includes the following steps:

Provide the specific parameters of the horn Xmax , Tmax, Tcoef, BL and Sd and the related datasheet.

Prepare the open horn and model it using PPC3.

Rough tuning by tuning engineer.

After confirmation of the whole machine and horn, do further modeling and fine tuning on the basis of the whole machine.
