The Arm system architectures define components and interfaces that make it easier for hardware and software to interoperate.
The Arm system architectures offer standardization and commonality across the ecosystem. These architectures offer strong compatibility and reduce the cost of ownership of software.
Arm provides system architectures free of charge to help the ecosystem and all system designers.
As well as contributing to existing industry standards, Arm creates standards for industry-specific system architectures. Arm's contribution to standards helps to ensure compatibility across the ecosystem.
Platform designs pull together CPU and system architectures into a platform definition that large bodies of software, such as operating systems, can rely on.
