Scale compute without redesigning software architecture

Arm Zephyr white paper cover image

AI Summary

As embedded AI workloads demand more processing power, memory, and parallel execution, developers need a path beyond microcontrollers that preserves their existing software investment.

Discover how Zephyr extends from Arm Cortex-M to Cortex-A processors, enabling developers to scale performance and workload complexity while maintaining familiar real-time operating system (RTOS) development practices. This white paper examines the architectural trade-offs, memory management models, and multiprocessing capabilities that make Cortex-A processors, including Cortex-A320, practical options for more demanding edge AI applications.

What you'll learn

  • Scale without starting over: Understand how Zephyr preserves a consistent programming model across Cortex-M and Cortex-A, reducing software redesign, porting effort, and maintenance complexity.

  • Make informed operating system decisions: Explore how Zephyr and Linux use AArch64 memory management differently, and what those differences mean for isolation, efficiency, and predictable execution.

  • Support more complex edge AI workloads: Learn how symmetric multiprocessing (SMP) enables real-time control, AI inference, connectivity, and sensor processing to run in parallel within a single RTOS environment.

  • Evaluate Cortex-A320 for your next design: Examine how greater compute capability, flexible memory protection, and multicore processing extend Zephyr to more demanding embedded and edge AI systems.
