Corstone-300 is part of Corstone Subsystem reference design that help designers build secure SoCs faster with the right architecture choice, integration, and verification. Cortsone-300 gives a quick route for SoC designers to include Arm’s most AI-capable Cortex-M processor, the Arm Cortex-M55 processor, into an SoC design.
Initial Software support is now available which adds support for Corstone-300 FVP (Fixed Virtual Platform) in the Trusted Firmware-M (TF-M). Corstone-300 FVP provides a complete Arm system including processors, RAMs, peripherals, and debug support allowing SoC software development before silicon is ready. TF-M provides an Open Source implementation of Secure Processing Environment (SPE) for Armv8-M architecture. It is the PSA reference implementation aligning with PSA Certified guidelines.
