Hello @sandeepchawla74,

 

It will depend on how it will be converted by the ST Edge AI Core. It is the C code version that is important.

 

You can see if your model fit in memory on the DK by running any command with the st edge ai core.

In the first table, you will see how your model is mapped in memory. For example:

Weights can be stored in external flash, and there is a lot of it in the N6 DK.

For activations, it is highly advised (for maximum performances) to have them fit in internal memeory (npuRAM1 to npuRAM4 = 4 * 448kB = 1792kB).

 

Have a good day,

Julian
