CCS/TMS320F28379D: 28379D VS 28035 CLA

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hi team,

I am confused with the difference between the CLA of 28379D and 28035. 

 I found that the control effect in 28035 was not as good as 28379 when they use the same control code. The positionless estimation results of the motor were quite different, and finally affect the closed-loop control. Both 28379 and 28035 used 12-bit ADC.

Besides,does the CLA of 28379 and 28035 have a big difference in computing power?

BR,

    Susan,

    There were no changes to the CLA architecture or instruction set that would impact computations.  The program memory reach was expanded and memory allocation to the CLA was made more flexible on F28379D.

    Differences in the device that could cause a change would be the

    • clocking speed: 200MHz for F2837xD vs 60 MHz for F28035.  
    • ADC: both devices have a 12-bit ADC but it is a different ADC - refer to the data manual for the specifications.

    Regards
