CCS/TMS320F280049C: Accelerate Fapi_calculatePsa() function

Part Number: TMS320F280049C

Tool/software: Code Composer Studio

Hello,

it is possible to speed up the execution time for Fapi_calculatePsa() function?

Maybe with the additional computing units.

  • Floating-Point Unit, Trigonometric Math Unit, Viterbi, Complex Math and CRC Unit (VCU)?

Time measurement of Function Fapi_calculatePsa() for:

Sector (0x80000 - 0x80FFF): 43 milliseconds
Flash- Bank0 (0x80000 - 0x8FFFF): 682 milliseconds

 

stay healthy,

Daniel

    Daniel,

    Fapi_calculatePsa() does not involve any specific flash algorithms except reading flash.

    Hence, there is no need to use this function if it can be accomplished by other means.

    PSA algorithm itself is given the Flash API guide's appendix.

    Thanks and regards,
    Vamsi
