IWR6843: IWR6843 L3 size

user5310849

Part Number: IWR6843

Hello TI,

There is inconsistency between IWR6843 datasheet and document "Introduction to the DSP Subsystem in the IWR6843". What is L3 size, is it 768 or 1024kB?

Thank you, Lukas

Hi,

The total usable L3 RAM for user application is 768KB

Strange, event the mmWave Sensing Estimator calculates with 1024kB (any radar cube size < 1024kB is valid).

There is 1024KB L3 Ram, user usable space is 768KB

Then, it could be nice to update Sensing Estimator to make it much less confusing.
