Geyserville <SpeedStep>
Alias:
IST and speed step, the Intel SpeedStep technology
Field:
Microprocessor > x86/Intel > Intel > Geyserville |
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, 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
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

GFLOPS <Giga FLOPS>
Reading: GFLOPS
Alias:
GFLOPS
Field:
Microprocessor > performance evaluation > GFLOPS
|
At one of the units which display the operation time of the computer, the fact that floating-point several operations of 1,000,000,000 time can be executed in 1 seconds is meant. As for FLOPS the prefix meaning which displays the operation time which with abbreviation “of Floating point number Operations Per Second” can designate the calculation of 1 times as 1 seconds, as for G (giga) means 1,000,000,000 (10 9 powers). There is many a thing which is used as efficiency index of large-scale computer system super such as computer.

GHz <gigahertz>
Reading: Gigahertz
Alias:
Gigahertz
Field:
Microprocessor > design/structure > GHz |
1,000,000,000 time is meant in 1 seconds, the unit of frequency and frequency. with the prefix meaning which means 1,000,000,000 time, GHz Hz (hertz: 1 times) 1,000,000,000 time, MHz 1000 times, THz (terahertz) it is 1/1000 time in 1 seconds.
Radio wave of the GHz band the microwave (UHF), the centimeter wave, strikes to ultra high frequency, is used in the portable telephone and the wireless LAN, television broadcasting, satellite broadcast communication, the radar and the microwave oven etc. Recently the microprocessor attendant upon efficiency improvement, clock frequency increases the product of the GHz band |
GIF
Reading: [jihu] and [gihu]
Full spelling: Graphic Interchange Format
Field:
Multimedia > graphics > picture type > GIF
Expression of information > file format > GIF |
| The picture type which with the American personal computer communication network CompuServe was developed in the one for picture exchange. It is possible, to retain the picture to 256 colors, it is faced to the retention of illustration and the idea contest etc which are poor JPEG. Appointing animation GIF and the being transparent bright color which can retain animated picture, interlace GIF etc which transparent GIF it is possible to superpose with background image,
As for the algorithm, LzW which is used in compression because the Unisys corporation has patent, the software which corresponds to GIF sale/is distributed, it is necessary to pay license charge to the Unisys corporation. Disliking this license charge, the picture format of license free, PNG was decided. |
