Hello, nxp developers

Can anyone confirm that hifi4 dap can be used as common dsp？ I want use it for sensor data calculation.

By the way, can uart be sxtended？We need 5 uart, but 8mplus datasheet say there are only 4.

thanks！

Hi,

Thank you for your interest in NXP Semiconductor products,

DSPs are used through their firmware, please refer to https://www.nxp.com/docs/en/user-guide/IMX_DSP_USERS_GUIDE.pdf.

I found the chapter about NatureDSP Library Support, is the library that matches the common operations of a DSP.

Used signal processing functions: FFT, FIR, vector, matrix, and common mathematics.

For UART expansion, you could either look for multiplexer/bridges or simulate a UART from GPIO, that development would be up to you.
