Communication is key, in embedded development and all other walks of life. Getting the most from your hardware often comes down to speed and synchronicity of communication, and never is this truer than with dual coretex processors.
By including both A and M-cortexes in a single MPU, such as the NXP i.MX93 and STM32MP1, you can combine high-performance processing capabilities with real-time control and efficiency.
Utilizing ARM architecture this way is great for Linux-based embedded systems such as those found in industrial automation, medical devices, and IoT gateways. However, getting those components to communicate is no easy task.
In this article, we delve into the pros and cons of five of the best communication methods available and some of the challenges facing those looking to take advantage of dual-core processing in embedded development.
