The semiconductor chip which does computing which is necessary for the indication of 3D graphics. In developmental shape of the tip/chip which was called the 3D graphic accelerator until recently, the processing which you take charge in comparison with the 3D graphic accelerator has become many.

The 3D graphic accelerator had taken charge, of only final rendering processing such as tipping the texture, but GPU undertakes the pretreatment in rendering, you take charge also the coordinate transformation and the like to 2D coordinate from 3D coordinate, can decrease the throughput of CPU.

The function which the programmer can use freely especially is increasing e.g., as for contents of the processing which GPU takes charge there is a tendency which increases gradually, it reaches the point where the filter for the special effect which the programmer drew up individually can be used.

The system which inputs letter by the fact that it is utilized by portable information terminal, Palm traces special letter on the touch screen.

This special notation is called “Graffiti letter”, consists of the private special character which corresponds to the thing and carriage return and the space etc which simplify the alphanumeric and the sign. As for these letters in the writing order which is decided from the start position which is decided the brief note or you must write with two writing brushes. Because of this, to do the input with Graffiti, some practice becomes necessary in order to write Graffiti letter accurately.

The fact that this kind of restriction is provided in Graffiti letter was the device in order character recognition accurately even in throughput of 1996 that time when Palm appears. Attendant upon the improvement of throughput of the Palm terminal, with the method of writing the usual letter close Graffiti2 has appeared in 2003.

The tub browser “Sleipnir” empty of the free software it derived, the tub browser for the beginners' class person. It is distributed as the free software.

Sleipnir seriously considers multi-function characteristic, Grani seriously considering handiness vis-a-vis being superior in customization characteristic, having simplified setting and the like is merit. Directly using Internet Explorer, is because it deals with the person who for the first time changes Web [purauza]. The eye which you saw, the buttons and the like are few, it has become the design to which the beginners' class person is difficult to be perplexed.

As for Grani, because, with customization characteristic such as the fact that Gecko cannot be used especially and the rendering engine which cannot do the installation of the extended tool bar it is inferior to Sleipnir, it changes to Grani, uses the browser and the use of Sleipnir is recommended to the user which is accustomed.

It is loaded onto PlayStation 2, the processor for graphic processing. Being highest, per 1 seconds it has the efficiency which draws 7,500 ten thousand polygons. In addition, DRAM of 4MB is accumulated inside the tip/chip, memory access can be done at maximum data rate 48GB/s. Because resolution is low (640x480), even with 4MB the data of the minimum can remember the television for home inside Graphic Synthesizer, but the amount which becomes insufficient means to use the main memory of 32MB. It is CPU of PlayStation 2, “Emotion Engine” it is tied by the bus of maximum data rate 1.2GB/s. As for operational clock with 150MHz, as for the number of accumulation transistors 4,300 ten thousand.
