RE: cc310 integration guide

Hi !

I need fast API without any malloc and etc. It should be possible to call those from SWI/ISR context.

They should be asynchronous in best case

Looks like direct cc310 is the best what I can find as part of SDK right now.

Regards,

Eugene

Hi,

[quote user=""]

I have found that AES operations are fastest if cc310 is used directly : examples/crypto/nrf_cc310/aes

Do you have any integration guide for library what use on top of cc310 crypto accelerator ?

[/quote]

We highly recommend that you use CC310 through the nrf_crypto library, and not with the ARM CC310 library API directly. nrf_crypto implements lots of parameter checks that is not present in cc310 library, so it is more robust against wrong usage. We do not have any other integration guide than the API documentation.

[quote user=""]Do you need any special memory allocators or all input/output/internal buffers are static and fully visible in example source code ?[/quote]

See Memory management in nrf_crypto.

[quote user=""]I can see enabling of CC310 interrupts are used but all APIs are synchronous and blocked. But can CC310 be used asynchronously ?[/quote]

You asked this in another ticket. There is no need to ask the same question in multiple threads.

Best regards,
Jørgen
