IWR6843: DSP oriented optimization

Hi Tom,

For general embedded software development resources related to TI mmWave devices, please refer to the resources listed in the following training:

Easy evaluation and development of mmWave systems with software development kit - Section "Software Development and Debugging"

and the following resources for the C674x DSP core in particular:

TMS320C674x DSP CPU and Instruction Set

TMS320C6000 Optimizing Compiler v8.3.x

Optimization Techniques for the TI C6000 Compiler

TMS320C674x DSP Cache

With regards to your other questions:

1. Are there  any neural network libraries optimized for 6843's DSP? basically matrix multiplications or convolutions.

Please refer to the following page: https://www.ti.com/processors/digital-signal-processors/libraries/signal-processing.html. Note that DSP lib and Math lib are installed as part of MMWAVE-SDK

2. Can we use CMSIS or partial CMSIS on 6843?

We have not looked into this but a quick look at the CMSIS documentation indicates that it is available only for Cortex-M and Cortex-A architectures and not Cortex-R. IWR6843 includes a Cortex-R4F core.

3. Can we use Matlab code generator for 6843?

Again, we have not looked into this so you will need to do your own research, including functional correctness and performance evaluation of the generated code, if such a capability is available for the C674x DSP core.

4. Any advice or examples.

Please refer to the resources listed above.

Regards
