Compiler/AWR6843: Sample Code of DSP part design question

Toyota-1
Expert 1100 points
Part Number: AWR6843

Tool/software: TI C/C++ Compiler

Dear TI 

         Our team will plan to hire a  DSP expert for optimizing TI's DSP sample code ( TI mmwave sensor)

         But we don't know which part need to be optimizing first , because we are all use MCU part to cover final result . 

         TI DSP sample code can run normally . It need to be modify for optimization ?  If DSP part need optimization can give us a guide for these optimization ?

    Hi,

    The most processing intensive operations on the DSP are the FFTs

    TI provides optimized FFT implementation in the DSPLIB (digital signal processing libraries) which are used in the mmwave SDK oob demo.

    So, there is no further need to optimze the DSP code

    thank you

    Dear Cesar 

               

               1 If we use the default DSP sample code for the application.    Which part needs to be modified? 

               2  Because we have to discuss with a much 3rd party design service house. they all say the TI DSP sample code is only for demo. It's real?

               3  TI default sample can't for product production use?

               4  Now we have sent some product samples to our customers  (with TI DSP sample Code +  Our MCU source code ) I don't know it's OK or not.

               5  DSP code is very low level logical for pure software engineers. Can give us some suggestion for us?

               6. TI R&D development mm-wave DSP use which tools and equipment, can share? ( We plan to purchase these for product design)

    Hi

    You are correct, the code provided is for demo purposes. As far as cycle count performance there is no need to further optimize it.

    The changes required in order to productize the code will depend on what your requirements are.

    Which demo are you interested in and what application?

    thank you

    Dear  TI 

                    Our company is using TI mm-wave radar for indoor and outdoor people or car counting applications. 

                    But at DSP part we don't know to change for these applications.  Our software team members are almost arm-base programmers. 

                    Because the project have MCU and DSP part.  Now our team capabilities only minor modify DSP part only.  

                    Can give some suggestions for designers to enhance this part.   ( Focus on algorithm or FFT or math ?)
