IA-64
:''Not to be confused with x86-64, the 64-bit extension to x86 architecture.''
IA-64 (also called Intel Itanium architecture) is the architecture of the Itanium family of 64-bit Intel microprocessors. The architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel.
The Itanium architecture is based on explicit instruction-level parallelism, in which the compiler decides which instructions to execute in parallel. This contrasts with other superscalar architectures, which depend on the processor to manage instruction dependencies at runtime. In all Itanium models, up to and including ''Tukwila'', cores execute up to six instructions per clock cycle. The first Itanium processor, codenamed ''Merced'', was released in 2001.
, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power Architecture, and SPARC.
