Hi Sir
We used AM3352 600MHz with DDR3 400MHz. And SDK is 04.03.00.05.
We found the reference of Crypto as below
We did the test and found the performance is different with above table.
below is our test report.
time -v openssl speed -elapsed -evp aes-128-cbc
You have chosen to measure elapsed time instead of user CPU time.
