 Preliminary Speed Results
posted by Johan Dams on 6th June 2009
Some early results:
The crypto-stack performs roughly 2 to 3 times faster on the i.MX515 than on the 5200B.
MPC5200B i.MX515
Field Tests (100 times)
-----------------------
Multiplication 0.0014 s 0.0007 s
Quad Solving 0.0500 s 0.0250 s
Inversion 0.0500 s 0.0200 s
ECC Test
--------
Scalar Multiplication 0.037 s 0.012 s
Operations
----------
Encrypt/Decrypt 0.130 s/cycle 0.042 s/cycle
Sign/Verify 0.100 s/cycle 0.030 s/cycle
Key Generation 0.030 s/key 0.012 s/key
Thanks to Peter for running the application on his system, since my development board seems to be broken.
These results are preliminary, but promising. More later.
Johan.
