TIDEP-01012: Which is right memory order about input of FFT Data?

user5243633

Part Number: TIDEP-01012

I develop radar firmware in PROCESSOR_SDK_RADAR_03_08_00_00.

I need the order of memory about input of FFT Data.

I found two fig in TI document.

But these isnt’ the same.

Fig 3. Output of ARxx sensor at P.4-168 in EVE_Applets_UserGuide.pdf

Raw ADC data in sec 5.2 DataFlow at P.27 in ProcessorSDKRadar_DataSheet.pdf

In first fig, range loop is first, doppler loop is second.

In second fig, doppler loop is first, range loop is second.

I want to know the precise order.

So, please give me a hit.

Hi,

Unfortunately the team that developed the Processor SDK Radar demo is no longer available for support.

I recommend you use the google site search to find similar threads in this forum

For example

site e2e.ti.com cascade data format processor sdk

Another way to find an answer to your question is to review the FFT processing function format in processor SDK.

From radar perspective, the range FFT is performed for each chirp. So, you should be able to see the format of the data in memory

thank you

Cesar
