TMS320F28386D: VCRC on EMIF

Clément Letonnelier
Expert 2876 points
Part Number: TMS320F28386D


Hello,

The TMS320C28x Extended Instruction Sets document states:

VCRC instructions can perform CRC calculation on the data stored in C28x ROM, RAMs and Flash to
check their integrity during application runtime. CRC can be computed by C28x application code by
using the CRC related VCRC instructions described in this section.

Do you confirm that it is not possible to perform it on an external memory (RAM type) through EMIF ?

    Clement,

     Do you confirm that it is not possible to perform it on an external memory (RAM type) through EMIF ?

    I should be possible for external RAM as as well. Basically any memory which CPU can directly read. Is it not working ?

    Regards,

    Ok I wasn't sure from the sentence in the document.

    I haven't tested yet, we are in an early design phase so our hardware is not available yet.
    I was searching for that info to see whether we would be using this module or not for our CRC computation and thus define the polynom in the specifications of the interfaced module.

    Guess I'll have to experience later on.
