RT685 FIR

[insert]

Hi all!

I want to make a filter for 10,000 taps for each of the 8 audio channels 48000(sample rate) on this processor. I can't find an example of a FIR filter for him. 

1. How can I better store the FP32 coefficients in memory (10000taps*4byte*8cahnnels)so that the Cortex M33 is not a bottleneck in the system?

2. Is there enough CPU power for such a task?

Hi,

RT600 is combining a high-performance Cadence^® Tensilica^{® HiFi 4 audio DSP core} . 

DSP core has advantage for data processsing vs. ARM Cortex-M33 core, which includes finite impulse response (FIR).

I would recommend customer to refer and download Cadence HIFI DSP software development toolchain from here.

Wish it helps.
