TMS320F2800137: AES tables in ROM

HS FAE Germany

Part Number: TMS320F2800137
Other Parts Discussed in Thread: C2000WARE

Hi,
I found AES table c-file in
c:\ti\c2000\C2000Ware_4_03_00_00\libraries\boot_rom\f280013x\revb\rom_sources\F280013x_ROM\bootROM\source\tables\

Is there any documentation how to use this AES tables?
Is there any CCS project?
Do you have performance measurements pure SW solution vs AES tables vs AES in HW?

Hi Holger,

My apologies for the delayed response. You can take a look at the source in C:\ti\c2000\C2000Ware_<version>\libraries\security\crypto\c28\aes and examples under C:\ti\c2000\C2000Ware_<version>\libraries\security\crypto\c28\examples\ccs.

These use the tables you are referring to.
