Qizhen,
The best way is to use the PurePath Console 1.16 which works with the EVM. There you can use the GUI to create your own custom filter and the GUI will calculate the biquads for you. You can then dump the register contents from the GUI and use it in your application.
Please apply for PPC 1.16 here: http://www.ti.com/tool/PUREPATHCONSOLE?keyMatch=purepath%20console&tisearch=Search-EN-Everything

Dear Adam,
I'm sorry to hear that. Can it be provided to us in the form of lib files?
Because our customers want us to open more sound regulation modes.

Looking forward to reply!
Qizen,
I found the attached file which you can use. Please note that this should be used with caution and at your own risk. TI makes no guarantees that this is correct or accurate.
