Architected to maximize the performance of constrained IoT and embedded devices, the Corstone-300 is a reference design based on the Arm Cortex-M55 processor and developed to help SoC designers build secure systems faster. The Corstone-300 can also easily integrate the Ethos-U55, the industry’s first microNPU.
The Corstone-300 includes a number of system IP blocks that provide the perfect starting point for SoC design.
Arm and partners offer software and tools that run on Corstone designs to help simplify and accelerate SoC development.
CMSIS Software Packs
