# metadata.contentDescription
The Morello architecture introduces a new data type - capability - to the Armv8-A architecture profile. The architecture extends the Armv8-A AArch64 state with the principles proposed in the Capability Hardware Enhanced RISC Instructions CHERI Instruction-Set Architecture, to provide hardware support for fine grain protection, and building blocks for secure, and scalable compartmentalization.
