CONTROL_DIE_ID

Does anyone know the breakdown of the CONTROL_DIE_ID number? Is there a section of it that identifies the die specifics and one part which is a count/unique code?
I'd like to get a 24 bit unique ID out of the 128 bits if possible for the same processor type. Is this possible?

Thanks,

  Ben

    Ben, this info is not available to the public.  Also, the DIE ID value is not guaranteed unique by TI, so you would not be able to use it as a unique identifier.

    Hmmm... On various net resources it is claimed (or better - assumed) that the DIE ID is indeed unique for every OMAP-chip. It would be really handy as it would spare me adding another chip and more code to have a unique platform ID.  But for the moment it looks like to me that the ID is "probably" unique but it cannot guaranteed - that's "probably" not enough for me to really rely on. An official statement of TI would for sure help here.

    Klaus, you are correct that it is probably unique in that it is made up of several values based on manufacturing, but we don't check it for uniqueness (ie, we don't have a database of all the IDs to ensure it is unique), so we cannot guarantee this.
