Part Number: AWR1642BOOST
Other Parts Discussed in Thread: TIDEP-0092

Hi,

I am using AWR1642BOOST with ES2.0 Silicon version.

I wish to study the use of Chinese Remainder Theorem (CRT) with multiple PRFs.

TI mmwave Reference Design TIDEP-0092 ( tidub36b.pdf ) mentions CRT on page 7.

However, I am unable to find the relevant part of code in the relevant lab .

I have searched CRT implementation in DSS of automotive toolbox 2.9.1 > labs > lab0002 short range radar.

Can you please advise the places where exactly I can find the implementation of CRT in TI mmwave codes (there could be more than one instances).

Thanks in advance

Hello Badar,

Short Range Radar and Medium range radar TI-Rex labs use CRT algo.

Please refer these two labs.

Regards,

Jitendra

Hi Jitendra,

Thank you for your prompt reply but I am sorry that I am still lost. Can you please take a little time more to guide me exactly where can I find code for CRT.

Moreover, I could not find or understand what is TI-Rex that you advised above.

In addition, I have already mentioned that I have searched CRT implementation in DSS of automotive toolbox 2.9.1 > labs > lab0002 Short Range Radar. But I could not find any part of the code implementing the CRT.

I request if you can guide me exactly where I can find the required part of code.

Thanks

Hello Badar,

Please allow me a day or two to confirm CRT implementation in any of the existing labs application.

CRT is implemented in SRR and MRR both of TI-Rex lab applications. Refer dss_data_path.c file of SRR and MRR and search for CRT.

TI-Rex I meant of TI Resource Explorer where we have many application for different mmwave sensor device variants.

hi,

I searched further deep into e2e posts.

I found that the following thread shows the exact location CRT implementation :
