IWR1642: Use cortex-M4F or use cortex-R4F and C674x?

Hello,everyone! I think i need you help.

I see that the U6 device patch in the BOM of the IWR1642 is the TM4C1294NCPDT, which is a 32-bit MCU based on the cortex-M4F. However, in the technical reference manual of the IWR1642, the master subsystem uses a cortex-R4F processor, and the DSP subsystem uses a C674x (which is not found in the BOM).

I am puzzled as a beginner and would like to be answered. I really hope to get help from anyone, and I'm very grateful！

Regards,

Jian Zheng

The IWR1642AQAGABL (U2) integrates the cortex-R4F processor subsystem and the DSP subsystem, while I don't know much about the role of the TM4C1294NCPDT (U6) for now.
