Can you use the DMA to do AES encryption

[henry_lovett]

Hi, 

I was wondering if it is possible to run the AES crypto using the DMA on a LPC54S018? The example code in the SDK uses a poll from the CPU, rather than DMA or interrupt based - is there any reason it is done this way? 

Many thanks,

Henry

Hi

The AES encryption and decryption engine supports DMA for transferring data between memory and the AES engine.

See user manual Chapter 45. Security features.  45.9.3 General description

However I just checked we don't have this demo code, user may make it by themselves.

Have a great day,
Jun Zhang
