Hello All, does anyone have a sample code that use FIR accelerator to perform real time audio processing at 48k rate on a sample by sample basis. I was able to do it using the core in a c++ implementation but not able to do it using the FIR accelerator. Thank you,
Hi Lingzhi ,
Please find the attached code for FIR which can run directly on ADS-21469 Ez-kit. You can use the attached FIR code to integrate with the ‘AD1939_I2S_Sampled_Based_Talkthru’. You would find the reference code "Talkthrough_IIR_Accelerator" which talks about the usage of IIR accelerator for filtering the data acquired by the codec AD1939.
Please find the code in the below path. Let us know if you have any further doubt."Installation\Program Files (x86)\Analog Devices\VisualDSP 5.1.2\214xx\Examples\ADSP-21479 EZ-Board\Talkthrough_IIR_Accelerator"
