rumor ps4 might use ps3 cell chip

With usual multiple core CPU, when the number of CPU cores is increased, various problems occur. For example, with just the traffic which maintains coherent of cache-memory, bus zone is eaten. With Cell B.E., the mechanism in order to prevent that from first is interwoven. Many of the game software developer do doubt apparent, architecture of private memory “local store” of each CPU core that is. 　With Cell B.E., cash was not provided in each CPU core, by the fact that it makes the local store which is accessed explicitly, necessity of [kohirenshimekanizumu] which becomes the fetter of CPU core several increases was lost, (conversely as for Larrabee of Intel it has become an important point) to develop [kohirenshimekanizumu] whose expansion is easy. When future workload moves to the stream processing center, because becomes only the data which is not reused, cash almost loses meaning, (the pre-reading buffer) with there was also the reading which is said. 　In addition, with Cell B.E., by the fact that it has the memory space where each CPU core becomes independent, it designated the memory space as portable, to distributed computing with respect to network tried to be able to expand to seamless. You must mind DMA to access to main memory from SPU, the inconvenience, there is a reason such as that. 　It was something in order Cell B.E. architecture itself, makes the increase of the future CPU core easy, to make the road to distributed computing easy. Cell B.E. is a strength in very developmental characteristic. As SCE, it is proper to think that we would like to develop this architecture even in the next PS4 generation. 　American Austen which by the way, SCE (SONY), in IBM and did the development of Cell B.E. with the engineer 3 of Toshiba STI Design Center, presently, as for the architect team of SCE it is said that almost it does not remain. It is seen that because of research of PS4 architecture, it is returned to head office side once. Because of that, with PS4 as for SCE also the possibility of leaving could think of Cell B.E. architecture. But, because when PS4 is examined in the Cell B.E. base, the directivity of PS4 decides SCE, with the result of research, it is presumed that development is restarted.
