IWR1642: Can IWR1443 examples be run on IWR1642 ?

Part Number: IWR1642
Other Parts Discussed in Thread: IWR1443,

Hello TI team,

I want to start developping with the mmWave sensors.

My application mainly focuses on drones : altitude measurement, obstacles avoidance, objet tracking.

If I'm not wrong the IWR family seems to be the best choice as IWR family is targeted at Industrial application and AWR at Automotive application.

My first concern is to do the same example as shown here : 

dev.ti.com/.../Drone Altitude - Setup Guide.pdf

I've read on another post that : 

I would recommend either the IWR1443BOOST or the IWR1642BOOST. The 1443 has an integrated Hardware Accelerator for doing FFT's and the 1642 has an integrated DSP which will enable things like object classification. The 1443 is a good starting point for most but if you think you'll need the DSP down the road then the 1642 is going to be your best bet. 

 

My question is : 

Is the 1642 just a better version of the 1443 ? Will I be able to run all labs example shown for the 1443 on the 1642 ?

Thanks,

Gregoire

    Hi Gregoire,

    The IWR1642 can be considered as a better version of IWR1443 in some sense but there are several key differences between the devices and how the desired processing is accomplished on the two. Both devices provide the ability to perform FMCW signal processing on chip to get the point cloud data with range, velocity and angle information. However the IWR1443 uses the hardware accelerator while the IWR1642 provides a C674x DSP for the same. The DSP on the 1642 allows the application to run more advanced functions such as tracking and classification, which cannot be done on the IWR1443. Correspondingly, the 1642 has more memory to allow advanced processing. So 1443 applications cannot run as is on the 1642 due the different digital processing engines. We do provide a few examples in our mmWave Industrial Toolbox with the same processing chain implemented on both devices e.g. the SDK Out of box demo, high-accuracy measurement, 

    I have attached a picture to show the difference from a signal processing perspective but I would recommend you to look at the IWR device overview video under mmwave-training-series on TI.com, for a detailed comparison.
