An Introduction to Asymmetric Multiprocessing: When this Architecture can be a Game Changer

An Introduction to Asymmetric Multiprocessing: When this Architecture can be a Game Changer and How to Survive It - Nicola La Gloria & Laura Nao, Kynetics

Asymmetric multi-processing (AMP) systems fulfill the need for high performance and real-time by combining the responsiveness of a MCU with the processing power of an application processor which runs a full OS.

This talk will present a technical overview on asymmetric multiprocessing platforms focussing on motivations, use cases and how to handle interprocess communication between MCU and MPU in practice.

Tools and strategies on how to develop software on such platforms will be presented, as well as debugging techniques which take into account the diversity and complexity of such systems. A case of study based on AMP architecture is analyzed. Low-latency tasks such as high-rate reading/sampling can be handled more easily and efficiently by the MCU core running a RTOS while data visualization can displayed by the Master core running a full Linux operating system.
