AWR1843BOOST: 256 POINTS FFT conversion time on AWR1843

Hi,

There are three ways to perform the FFT on AWR1843.

The first and second one are using the DSP

• Fixed Point FFT
  • See https://www.ti.com/lit/an/swra552/swra552.pdf
  • Section 3.1 Benchmarks. The DSP Clock is 600MHz

• Floating Point FFT
  • See "dsplib_c674x_3_4_0_0"

The third one is using the HWA

• See https://www.ti.com/lit/ug/swru526b/swru526b.pdf
• Table 5 FFT Computation Time (the HWA clock is 200MHz)

Thank you

Cesar
