Itanium processor

We all are familiar with the processors that are used in our computer systems and mobile phones. Now let us have a look at such a processor named as Itanium processor. Have you heard about an Itanium processor? The Itanium brand extends Intel’s reach into the best level of computing enabling powerful servers. And high- performance workstations to handle the increasing demands that the net economy places on e-business. The Itanium design may be a distinctive combination of innovative features, like predication, speculation, explicit parallelism and much more.what is an itanium processor
Intel said the Itanium offers a 12-fold performance improvement over today’s 32-bit designs. Its “Explicitly Parallel Instruction Computing”(EPIC) technology allows it to handle parallel processing other than previous designs, most of which were designed 10 to 20 years ago.

The technology reduces hardware complexity to better modify processor speed upgrades. Itanium processors consist of “massive chip execution resources” that permit “breakthrough capabilities in processing terabytes of data”. Itanium is the 1st processor to use EPIC (Explicit Parallel Instruction Computing) design. Moreover, Its performance has to be better than the present day Reduced Instruction Set Computing and complex Instruction Set Computing (RISC & CISC).

One of the main features of Itanium is its use of a “smart compiler” to optimize how instructions are sent to the processor. Moreover This approach permits Itanium and future IA-64 microprocessors to process more instructions per clock cycle.

Itanium is viewed by Intel and industry observers as a new level of hardware platform for the UNIX system and Windows server market. Also for the high-end pc workstation market with its memory- and graphics- technical, intensive scientific and high-end graphics applications. Observers say that Itanium-based servers are particularly suited for today’s massive enterprise computing environments with information warehouses and a requirement for intensive processing for complicated queries and transactions.

Now let us see some of the benefits that Itanium brings to us:what is an itanium processor12
  • Reliability:

    ‘Reliability’ refers to the ability of the hardware to prevent failing. With the Itanium processor family, this ability is made directly into the processor. The main example of the improved reliability of the processor is the constitutional ‘error correcting memory.’

  • Availability:

    A system with 100 percent ‘Availability’ could be a system that\’s always up and never down. At present, the 100 percent threshold is just theoretically attainable, partially because of the unpredictability of random errors, natural disasters, needed maintenance, upgrades and in fact ‘hard’ and ‘soft’ errors. Generally, the reason systems tend to crash and go down is due to these last 2 types of errors.

  • Serviceability:

    On a typical Itanium-based system, you can pull out the card while the system remains running and plug another one in it’s ‘instantly serviceable.’ this is usually a capability that has been designed into the architecture. In the case of a multi-processor, you can shut down one processor and substitute in a new one. The ability to service the machine while it’s still running reduces your down time even more. It’s just like being able to exchange a flat on your car while in the middle of your freeway commute.
