I am currently working on an IoT project using a Toradex SoM (Apalis iMX8), and I have been facing some challenges with optimizing the system performance. I am trying to fine-tune resource usage to get the best performance for my specific use case, which involves handling real-time data processing and multiple sensor inputs. When I was Googling for the same I came across these resources/articles Achieving exceptional graphics for IoT devices of tomorrow - i.MX 8 and Crank SoftwareGenerative AI Interview Questions however they are good but I want to learn more from community members.
Has anyone here had experience with similar setups? Any tips or suggestions on how I can reduce latency or improve power efficiency? I’m also curious about what tools or methods you use to monitor performance.
Thanks in advance! Looking forward to hearing from the community.

To optimize the performance of your IoT project using the Apalis iMX8, especially for real-time data processing and handling multiple sensor inputs, you can consider the following strategies:
Power Consumption Optimization: Refer to the power consumption measurements for the Apalis iMX8 provided by Toradex. Understanding the power profiles under different loads can help you design your system to be more power-efficient. You might want to measure your specific use case to tailor optimizations.
Real-Time Performance: Ensure that your system is configured for real-time performance. This might involve using a real-time kernel or configuring the existing kernel to prioritize real-time tasks. You can also explore using Torizon, which is designed to simplify the deployment of real-time applications.
Resource Monitoring and Profiling: Use tools like top, htop, or perf to monitor CPU and memory usage. Profiling your application can help identify bottlenecks. For more detailed analysis, you might consider using gprof or valgrind.
Memory and I/O Optimization: Use benchmarks like Tinymemcbench to understand memory bandwidth and latency. Optimize your application to make efficient use of memory and minimize I/O operations where possible.
Parallel Processing: If your application can be parallelized, make use of the multiple cores available on the Apalis iMX8 to distribute the workload.
Carrier Board Design: Ensure that your carrier board design is optimized for your specific application needs. Toradex provides resources and tools like the Pinout Design Tool to help with this.
Community and Support: Engage with the Toradex community and technical support for specific advice and shared experiences. They can provide insights and solutions that are tailored to your specific challenges.
By focusing on these areas, you should be able to improve both the performance and efficiency of your IoT project. If you need further assistance, consider reaching out to Toradex’s technical support or their partner network for more specialized help.

I’m not sure if I understood your project requirements, can you describe better what is the goal?
The apalis imx8 (and the apalis family in general) are designed for high performance and heavy image processing tasks, like using 3D GPU and high-end graphics.
For a use case that involves external sensors readings and low level tasks, such as what you described, I think the apalis family may not be the best starting choice. Have you checked the verdin AM62?
Are you using the Apalis’ cortex M4 core for that? How are you communicating with Linux?
