An Introduction to Asymmetric Multiprocessing - When This Architecture Can Be a Game Changer

Explore asymmetric multiprocessing (AMP) architecture in this 52-minute conference talk from the Linux Foundation. Discover how AMP systems combine MCU responsiveness with application processor power for high performance and real-time capabilities. Learn about motivations, use cases, and practical interprocess communication between MCU and MPU. Gain insights into software development tools, strategies, and debugging techniques for complex AMP platforms. Examine a case study demonstrating efficient handling of low-latency tasks on MCU cores with RTOS and data visualization on Linux-powered master cores. Delve into topics such as hybrid architectures, supervised vs. unsupervised systems, RPMsg on Linux, and a hybrid Linux/FreeRTOS demo. Understand potential pitfalls and access valuable references for further exploration of AMP systems.
