IWRL6432: Bit rate of SPI interface

? ??
Prodigy 20 points
Part Number: IWRL6432

Hi，
    I'm trying to develop a real-time multi-target activity recognition algorithm.

    To support complex deep-learning classification algorithms, I want to connect IWRL6843 to S905D3(Quad-core ARM Cortex-A55 CPU) through SPI interface. 

    What is the SPI bit rate can be up to?

    If extracting features from group tracker info, the SPI interface bit rate can support simultaneous tracking of 3 targets.

    Hello, 

    From our own testing we have noticed issues when the SPI frequency is increased beyond 26MHz. You should have no problem outputting the group tracker info for 3 targets while staying below this frequency. 

    Best Regards,
