TMS320F28379D: CLA comparison between F28069, F28379, F280049

Champs,

Do we have any doc for CLA enhancement and comparison between F28069, F28379 and F280049?

Our customer used F28069 CLA before, and is evaluating if and how CLA is improved on F28379 and F280049.

    Wayne,

    If it helps, I have a few documents and video presentation that covers the enhancements to the Type-2 CLA:

    "The TMS320F28004x Microcontroller: A Comparison to the TMS320F2806x and TMS320F2803x Microcontrollers" www.ti.com/lit/sprt731 (see section 2)

    training.ti.com/technical-introduction-new-c2000-tms320f28004x-device-family

    Also, you might want to use the CLA module from each of the following workshops for a comparison between F28069 and F28379:

    For the F28069 (see module 10) -
    processors.wiki.ti.com/.../C2000_Archived_Workshops

    For the F28379 (see module 9) -
    processors.wiki.ti.com/.../C2000_Multi-Day_Workshop

    Ken,

    They are useful, thank you for your information.

    I also made a simple comparison table for our customers.

    Would you please take a look and let me know if there is anything to be revised?

    Wayne
