| | IA-64 - Wikipedia, the free encyclopedia |
 | | In computing, IA-64 (Intel Architecture-64) is a 64-bit processor architecture developed in cooperation by Intel and Hewlett-Packard, implemented by processors such as Itanium and Itanium 2. | | | The goal of Itanium was to produce a "post-RISC era" architecture, using EPIC [Explicitly Parallel Instruction Computing]. | | | For example, the Itanium functional units do not automatically generate integer flags as a side effect of ordinary ALU computation, and do not intrinsically support multiple outstanding unaligned memory loads. |

| | To save face in some respects, Intel puts a spin on it which comes in the form of various websites saying things like the delay might actually be a blessing in disguise for software developers, as they'll now have more time to develop their Itanium software prior to the chip's release. | | | Intel publicly demonstrates a four-CPU Itanium at LinuxWorld and at The Intel Developer Forum. | | | Itanium represents a whole new way of thinking when it comes to executing software. |

| | If Itanium software has to be optimized for Linux or Microsoft products, HP may then only be able to support the optimization of HP-UX software at great expense--a cost which may be absorbed by customers. | | | Itanium uses Explicitly Parallel Instruction Computing (EPIC), which is entirely new and it lends considerable complexity to the task of porting applications. | | | While the Itanium 2 processor offers emulation for IA-32 binaries under Windows or Linux, this is done by running in an IA-32 emulation mode, with all the performance issues that implies. |

| | Itanium is a processor for high-end servers in data centers and high-performance computing shops. | | | However, it uses a different instruction set than the 32-bit x86 Xeon processor, and software developers initially balked at having to port all their applications to an unfamiliar instruction set. | | | The chip maker has since backed off its original statements about Itanium and is now promoting the chip as a high-performance replacement for reduced instruction set computing (RISC) processors in Unix servers from companies such as Sun Microsystems and IBM. |

| | In the late '80s, Intel and HP outlined plans for Itanium, in part to correct some of the limitations of the x86 chip architecture, which was the basis for Intel's chips at the time. | | | The decline could reinforce the gloom that surrounds the chip and be seen as a harbinger that computer architects are losing interest in it. | | | A new, albeit delayed, version of Itanium 2, code-named Montecito, is coming soon, which could reinvigorate Itanium's position. |
