Can you recommend an Arduino with large ram space?

Hi, I want to test the DSP cross-correlation algorithm on an Arduino board, which requires relatively large ram space, but I am new to Arduino, so can you recommend me one?
Thank you very much

How much ram is "relatively large"?

I would say, about 80KB

Due, ESP8266, ESP32.

  • Teensy 3.5, 3.6

But why must it be an Arduino? A Pi Zero W has more ram & speed & costs less than most of the above suggestions.

THx, so does this device support "wire language" and some easy-to-use libraries just like arduino?
I mean, I want to directly test the algorithm, I don't waste time on the I2S driver those stuff.

Cross-correlation like this one ?:

which arduino library would you like to use ?

Yes, and I just want to use the I2S library.
Does Arduino have algorithm for cross-correlation algorithm?

This question is a nonsense !

Elaborate your project (a uni assignment ?). Maybe an arduino can do the job but I doubt that you could find a code all done without having to work the subject by yourself.

just I2S driver is fine, I thought arduino even has algorithm libraries...
