TMS320F2800156-Q1: CMAC + AES compile size

Ambroise Suter

Part Number: TMS320F2800156-Q1
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello,

We are planning to use the TMS320F2899156-Q1 and require AES encryption. Do you have an estimate on the added code size on flash for the CMAC and AES library?

Thank you and best regards,

Hello Ambroise,

The total compiled size of the AES library is ~1.32KB on Flash. This is with -O2 optimization.

Best regards,
Ibukun

Hi Ibukun,

Thank you for your answer. Does this also include AES-CMAC library or only AES? We also wanted to know the library size of CMAC.

Best regards,
Ambroise

Ambroise,

Yes, this includes CMAC. Specifically, this is the compiled size of the AES code from the CMAC example provided in the C2000Ware, excluding the main function. It covers all library code and constant arrays used to perform the AES-CMAC computation.

Best regards,
Ibukun

Hi Ibukun,
Thank you for your clarification.
Can you also share memory size figures for the other algorithms that are supported ? RSA, SHA, ECC/ECDSA

Thank you and best regards,
Ambroise
