AM572x: Using AES hardware accelerator from DSP

Brad Caldwell

I can’t seem to find any direct documentation from TI. Hoping you can help. For the AM57x family, does the DSP have access to the crypto accelerator block through one of the interconnects? Wondering if the DSP can use hardware AES acceleration.

The factory team have been notified. They will respond here.

Yes, AES hardware core public side HIB can be accessed via DSP. TI has no AES driver/SW running over DSP.

Thanks. I have a follow-up question, due to the nature of the IP block I think I know the answer but I'll ask anyways.

Can TI provide detailed documentation on the crypto IP blocks? Enough to allow a customer to create their own driver on the DSP side?

Brad,
Crypto doc is under NDA.
