SDRAM which accelerates by the [bachiyaruchiyaneru] architecture which NEC developed. It builds in the circuit which in memory chip operates to high speed, usual SDRAM compared to it can designate the input/output of the data as high speed by storing the data temporarily there. VC SDRAM is utilized, it is necessary to use the motherboard which corresponds.

The emulation function of MS-DOS which Windows has.
As for Windows NT and the like because 16 bit application of MS-DOS and Windows 3.1 etc cannot be executed that way, executing VDM, it has reached the point where it executes application on that.

The one of xDSL. Using the telephone line of 1 pair, it communicates. To be the same asymmetric speed type as, as for transmission rate central telephone exchange -> user direction (the descent) with 13Mbps - 52Mbps, the user -> central telephone exchange direction (rising) 1.5 - 2.0Mbps. Maximum transmission distance descends and descends 300m (52Mbps) - 1.4km (13Mbps). When high speed communication service is offered at the multiple dwelling house and the like making use of the telephone line net inside the building and the like, it is utilized. At that time, in order to utilize high-speed characteristic the outside line (the circuit to central telephone exchange) there is many a thing which combines the optical fiber from the building.

While long haul continuing to look at VDT of display and the like of the personal computer, . The haze of eye spirit fatigue and vision decrease and the eye, pain of the eye, you can list the dry eye and the scotoma etc as an example of the direct body disease. As for cause of these conditions, the brightness of VDT and thing and the long haul VDT to which contrast is too strong the occasion where are carefully observed the [ma] it means that among other things frequency of going back and forth decreases.
Even in addition, locking long haul attitude before VDT, the tendovaginitis which happens such as pain of body such as stiff shoulders and the lumbago by working and with keyboard operation also body condition is included in VDT obstacle. As example of the mental disease there is an emotion instability and a sleeplessness etc which happen by long haul doing monotonous data entry job and the like

.
Lumping together the data of 128 bits, it receives, this can divide into several integers and the number of floating-points and can process.
AltiVec lumping together the enormous data, because it can process, low being possible to execute abundant processing even with the clock, makes, the processing which such as especially animated picture playback handles the mass data and 3D rendering proud.
But as for naming, AltiVec those where the Motorola corporation designates, at the Apple corporation which sells the PowerPC G4 system the same function is called “Velocity Engine”.
