SWRZ089C December 2018 – December 2020 AWR1843
Number of Samples (SRCACNT) Should be >3 for Correct Operation of FFT Hardware Accelerator
AWR1843 ES1.0
Logic which subtracts the compute engine pipelined delay from FFT counter wraps around incorrectly when the number of samples is less (specifically, when it is 3).
FFT engine should not be used with FFT counter value < 4.
