The IA-64 architecture defines the following three firmware layers:
- Processor Abstraction Layer
- System Abstraction Layer
- Extensibile Firmware Interface
The System Abstraction Layer is a firmware layer that isolates the operating system and other higher-level software from implementation differences in the platform, while the Processor Abstraction Layer is the firmware layer that abstracts the processor implementation.
