32 bit microprocessor which Hitachi, Ltd. developed (MPU). It confronts the 3rd generation of the SuperH series of the same company. To drive at maximum operating frequency 60MHz, as for operation time being highest, 78MIPS. Because Windows CE of the Microsoft corporation supported SH-3, each company adopted as CPU for hand-held PC. There are 2 types of SH7702 of SH7708 and inexpensive edition.

Microprocessor > RISC > SH-4

32 bit microprocessor which Hitachi, Ltd. developed (MPU). It confronts the fourth generation of the SuperH series of the same company. It drove at maximum operating frequency, 200MHz installed operation time and it achieved highest 360MIPS for the equipment as MPU. In comparison with SH-3 of 1 generations ago, efficiency with such as adoption of the sou pass color system which executes plural orders simultaneously and expansion to 64 bits of data bus has improved substantially. The graphic engine of 128 bits is built in, 3 dimensional graphic processing of approximately 5,000,000 polygon is actualization possible in 1 seconds. It is adopted with game machine Dreamcast for the home of hand-held PC and Sega [entapuraizesu] which load Windows CE as OS.

One of the hash functions (summary function) which are used in certification and digitalized signature etc. “Hash value” of 160 bits is formed from the original of 64 power bits or less of 2, it is possible to detect whether by the fact that it compares with the both ends of channel, the original is not altered communication midway. Because irreversible unidirectional function of initial value susceptibility is included in calculation method, hash value takes the value like false random number, cannot reproduce the original on the basis of this. In addition, also quite it is difficult to draw up another message which forms the same hash value. It was adopted in 1995 as standard hash function of the American government depending upon the National form technical bureau (NIST). It is applied to IPsec and the like in order to do communication safely on Internet.

3 dimensional graphic compilation software of x [tsurusu]. There is the type “of Shade Professional”, “Shade Personal”, “Shade Debut” and “myShade” etc depending upon use, respectively there is a Windows edition and a Macintosh edition. Cheapness the empty it is supported in wide layer with the real modeling function by the free curved surface. Ray tracing method and radio city law (only Professional) supports as a rendering system.

One of the file sharing software in Japan being developed & being distributed. The computer which Share has started (the node) in between, through Internet, it is possible to exchange the file. It operates with Windows environment. First version was released in 2004 January.

Around 2003 end of year, the similar file sharing software “Winny” whose at that time popularity is high (Winny2) with the arrest person of the Copyright Act violation appears, the situation that was received, the writer receives residence search, the large-scale bulletin board sight “2 don't you think? Share development started from argument with the file sharing software-related bulletin board of the [ru]”. From these kind of details, the viewpoint which like “the succession software of Winny” catches Share it is many. However, as for Share there is no direct compatibility of Winny, it is the software which was developed in new specification.

Hitachi, Ltd. (presently in [runesasutekunoroji] transferring) developed, the integrated tip/chip of 32 bit microprocessor (MPU) and 16 bits DSP. You can call the thing which raises the DSP efficiency of the processor of the SuperH series of the same company to a greater extent. To drive at maximum operating frequency 60MHz, as for MPU efficiency being highest, as for 78MIPS and DSP efficiency being highest, 120MOPS.
