As for loading onto PS4 the developmental type CPU of Cell B.E. 　SONY [konpiyutaentateinmento] (SCE) next term game console “PLAYSTATION 4 (PS4)”, Cell Broadband Engine (Cell B.E.) real examination has been begun with the direction which is made the architecture base. Presently, you infer the reaction of the game developer, you are said that it is the stage which searches concrete mounting. SCE, when in the PS4 generation production cost is lowered from the PS3 generation, simultaneously, seems that aims toward the road which development investment is held down by the fact that it continues architecture. 　Also the possibility SCE leaving from Cell B.E. with PS4 being still left, it enters, but for the present, the expansion & of Cell B.E.; It is seen that it is moving with the direction which designates the revised edition as the base. 　SCE at the stage which PS3 project materializes originally, had planned the fact that it continues Cell B.E. architecture even in the generation after PS3. Betting enormous cost on because of that, it developed Cell B.E. as the CPU architecture which withstands the development which crosses the long period of time. The original conception of PLAYSTATION which is the Cell B.E. base was magnificent ones which finally distributed computing with respect to network were inserted in range of vision. 　It is seen the plan of present PS4 is visible, in order from the fact that Cell B.E. is designated as the base, to be close to the extended strategy of originally PLAYSTATION+Cell B.E., but that inside that to tell the truth it differs completely. In order to hold down the investment to hard and the software, Cell B.E. it is the story that it develops PS4 in the base. Already if Cell B.E. and software stack on that and the investment to the tool which do enormous investment, it is possible, we would like to succeed, it is thought that is the aim of SCE. In current SCE, as the time of PS3 probably there is no sufficient room which does the development investment of the same scale, even in the following generation. 　In addition, it is seen that with PS4, you hold down also the scale of the tip/chip, itself you face to the direction which reduces production cost. But past with PLAYSTATION of 2 generations, concerning 2 tips/chips of main, the die/di (the semiconductor itself) approximately 200 squares mm the high performance of large-sized size, high cost you started with the tip/chip, with process refinement the tip/chip shrank and you took production cost and the strategy which reduces price. But, it is estimated that in the PS4 generation, in order low to oppose to Wii of cost, from the first machine it reduces production cost with the small tip/chip, reduces also selling price. As for ●SCE the direction which holds down the number of CPU of PS4 cores? 　As for PS4, becoming how much performance rise vis-a-vis PS3? Cell B.E. of PS3, CPU core “PPU for control (POWER Processor Unit)” in 1, CPU core “SPU for operation (Synergistic Processor Unit)” 7 (originally with 8, 1 disabling) has loaded the total 8 CPU cores because of yield rate. And, as for Cell B.E. by the fact that the number of CPU cores is increased to scalable, it has become the architecture which can extend efficiency. 　So, with PS4, reaching to the number the CPU core such as 32? As for present Cell B.E., because while basic layout of 90nm edition is maintained it has shrunk, extent of reduction of the die/di is small. Vis-a-vis 235 squares mm of 90nm edition, as for 65nm edition 175 squares mm, as for 45nm edition they are 115 squares mm. But, if it does again to design for the second time with the PS4 tip/chip, there is a possibility where it can load the CPU core of considerable number with 45nm (Toshiba has decreased the area of the SPU core largely). Originally, if sort “of the [ikeike]” plan of SCE, there was a possibility of developing into Cell B.E. such as 24 cores and 32 cores with 45~32nm. If sort of Moore's law, it reaches to 32 cores. But so it will not perhaps do current SCE.
