久多良木健在周一于美国三藩市举行的国际固态电路会议(ISSCC)上就cell处理器的相关问题作了演讲。在演讲中，他提到，在目前基于像素技术的对图像真实性的追求上，电子娱乐系统所能达到的水平已经赶上了电影。
真实的动作表现需要大量的物理模拟，如果缺乏这一点，总体的图像表现则不会比现在的PC系统有很大的提高。由索尼，IBM，东芝合力开发的cell处理器在单精度浮点运算上的表现等同于200+Gflop的超级计算机。久多大叔相信，cell处理器配合宽带网络，将能够最终主导市场。系统反映的改进改变了人和机器之间的联系。即时的网络计算需要解决现在的网络瓶颈问题，例如服务器。而建立一个基于cell处理器的类超级计算机网络将是另一个解决方案。使用cell处理器将降低所需要交换的数据量从而保证实时的反应。
久多大叔还提到了“自由场所”的概念，用户可以从任何地方通过网络登陆其家中的电脑。如果拓展这个观点，同样我们可以从任何地方登陆我们的电子娱乐平台，一个移动的客户端可以实时的显示PC娱乐系统的内容，作为交互界面。
演讲没有关于PS3的新内容。
Kutaragi ***es Cell Chip At ISSCC
Real-time computing will bring a paradigm shift for both the PC and semiconductor industries, according to Ken Kutaragi, plenary speaker at the International Solid State Circuits Conference in San Francisco on Monday (Feb. 6).
"In the pursuit of reality through pixel-based technology, graphics on computer entertainment systems have reached the same level of quality as that of the latest movies," said Kutaragi, president and CEO, Sony Computer Entertainment (Tokyo). Kutaragi touted the Cell processor, which is being used in the PlayStation 3, as the means for generating high-quality natural motion for moving objects, just as "pixilation" was used to improve computer graphics.
Natural motion requires vast amounts of physics simulation. Without it, overall graphics would differ little from existing PC entertainment systems. The multicore Cell processor—developed by Sony, IBM and Toshiba—has achieved single precision floating-point calculation performance equivalent to a 200-plus-Gflop supercomputer.
Kutaragi predicted the Cell processor connected to a broadband network could eventually dominate the market. "If you follow the course of computer history, you see how the quest for constant semiconductor scaling and the equal quest for ever higher performance have led to where in 2006 a single chip such as the Cell is one-sixth the size of the original two chips brought out in 1998," said Kutaragi.
"Improving system response changes the relationship between computers and humans," said Kutaragi, citing the example of real-time computing in Formula 1 racing cars packed with sensors and processors that are monitored by a supercomputer miles from the racetrack.
Real-time network computing would require the upgrading of network bottlenecks like servers and switches. Instead Kutaragi proposed forming a Cell-based supercomputer-like server as an application server accessed by many client systems. By incorporating Cell processors, real-time responsiveness could be secured by exchanging only a small number of objects.
Kutaragi noted that the "location-free" concept enables users to access their home terminal via the Internet. "By expanding this concept, it will also become possible to access computer entertainment systems in the home, from mobile clients, in real-time," he said. Thus, mobile clients become a remote display and interface for PC entertainment systems. "Computer entertainment systems and applications are now leading this trend," said Kutaragi. |
