This standard describes the Heterogeneous System Architecture Intermediate Language (HSAIL), which is a virtual machine and an intermediate language.
An HSA implementation consists of:
• Hardware components that execute one or more machine instruction set architectures (ISAs).
• An HSA runtime that is a library of services that supports the execution of HSAIL programs including a finalizer and a loader:
o A finalizer translates HSAIL code into the appropriate native machine code if the hardware components cannot support HSAIL natively.
o A loader loads native executable code onto hardware components.
