IST SpeedStep

Full spelling: Intel SpeedStep Technology
Alias:
Geyserville and speed step, the Intel SpeedStep technology
Field:
Microprocessor > x86/Intel > Intel > IST

The power saving function which from Mobile Pentium of the Intel corporation III is loaded. As for development code name “Geyserville”.

When power source is offered from the AC adapter, when it operates with high tension, & the high clock changes to battery operation it decreases the voltage clock, extends operating time.

With battery drive mode it operates with the voltage clock of approximately 8 tenths of AC drive mode, electric power consumption retrenches in approximately half.

In addition, also it is possible to appoint the operational mode of specification mandatorily making use of the utility for Windows.

As similar technology, there is a LongRun technology which Crusoe of the Transmeta corporation is on-board as for SpeedStep the clock has been modified with supply power source, but as for LongRun technology vis-a-vis modifying the clock according to load.

Microprocessor > x86/Intel > Intel > Itanium

Brand name of 64 bit microprocessor of Intel corporation.

The Itanium series has designated the IA-64 architecture which the Intel corporation and the Hewlett Packard corporation developed jointly as the base.

Because in the Itanium series, is called IA-32, the x86 microprocessor of Pentium and the like, and the program which was drawn up to the one for PA-RISC series of the Hewlett Packard corporation it can execute, it is possible to utilize former software property.

Whenever Itanium with common brand name of the IA-64 based Intel corporation make processor, the generation advances, like “Itanium 2” product name keeps upgrading. Presently the product which release is done is Itanium 2 which has the code name, “McKinley”.

Itanium 2

Field:
Microprocessor > x86/Intel > Intel > Itanium 2

It becomes succession “of the Itanium” processor of the Intel corporation, the 2nd generation 64 bit microprocessor. For the [haiendosaba] work station which is announced in 2002 May with the product, as for the code name when developing “McKinley”.

It follows to the first generation Itanium and besides the fact that it operates that way, also the IA-32 based application software can OS and the application software which were drawn up to one for Itanium with the product which designates IA-64 architecture as the base, operate.

Besides the fact that in the efficiency aspect 3 next cash of maximum 3MB were integrated to the processor core, primary cash (32KB) and the secondary cache (256KB) to also access time was shortened, 8 steps and very we have become short with when the pipeline is shortest, efficiency around 1 clocks has become very high. Also the number of simultaneous order issues 11 has become many, per clock improvement of efficiency is assured even at this point in time.

iTAP

Reading: Eye tap
Field:
Portable telephone > terminal > iTAP
Software > type > Japanese input > iTAP

The Motorola corporation developed, letter input method of word estimate type. It is one of the methods of being devised in order to do letter input efficiently in the key which with the letter input system for the portable telephone, is limited.

Using iTAP, the case where it inputs letter, estimate word that it inputs only consonant, it is indicated as candidacy, it selects the word which from among those we would like to input. Usually, if for example it is kana letter, consonant is allotted every key, means to input intended letter by several degrees pushing the same key, but because with iTAP 1 letters the frequency which pushes the key the occasion where it inputs 1 times, it is possible to do input quickly.

iTAP included Japanese, it corresponds to many languages. In Japanese edition among these you can store to the dictionary 35,000 languages, not only the portable telephone, being utilized as application for letter input is considered with the embedded type equipment of PDA and the like. But, still there is no adoption example in the country of iTAP. There is “T9” and so on in the input method which is similar to iTAP.

ITIL IT inhurasutorakuchiya library

Field:
Enterprise information system > computer system > ITIL

The English government decided, the systematic guideline regarding the operational administrative work of the computer system. It is collected in the form of the book of several volumes, OGC of the same Government agency (Office of Government Commerce) and the like from can procure.

The eighties, as for the same government from the fact that you cannot obtain the effect which is expected vis-a-vis the investment to IT, forming the project team, you investigated the advanced case of IT application, the model case (the best practice) collected, “utilized IT and you systematized as the methodology which helps the accomplishment of business”. This is ITIL.

With ITIL, management of the computer system and the use, accomplishment of business is helped as “IT service” to consider, offering appropriately service in compliance with request, you have aimed toward the fact that it keeps improving continuously with the high investment anti- effect. From such point of view, operational administrative work, in order to be able to utilize the service where daily the user is necessary it supports at high investment efficiency in the long term it keeps improving “service support” and, service, dividing into two of “service delivery,” you think. And, both are divided into the process 5 - 6 respectively, the model case has been shown.
