在计算机诞生的初期,还没有现在类似Windows的多任务操作系统,人们关注的重点在于单任务程序的执行性能,当时人们评价处理器性能时主要参照办公软件、字处理软件、电子表格软件这样的单任务执行速度。而如今,3D游戏、三维创作、多媒体文件处理这样的应用占据了大部分使用者处理器的多数时间,对于这些应用,注重单线程性能的传统架构已经显得不合时宜。05年年初,Intel、AMD的一系列动作清楚地表明,处理器产业已经找到了新的大幅度提高处理器性能的方式--那就是“多核心处理器”,未来的处理器性能设计将会把焦点从原来追求ILP性能向多核心处理器所能释放出来的多线程并行能力转移,即TLP性能。目前对于Intel和AMD的多核心处理器技术方案已经在产品上实施,而本文所要讲述的“CELL”处理器则是完全不同的另一种呈现,下面我们就一起来揭开“CELL”的神秘技术面纱。
Early in the birth of the computer, there is no multi-tasking operating system similar to Windows now. The focus of attention is on the execution performance of single-tasking programs. At the time, when evaluating the performance of processors, the main reference to office software, word processing software and spreadsheet software Single task execution speed. Nowadays, applications such as 3D games, 3D authoring, and multimedia file processing take up most of the processor time for most users, and traditional architectures that focus on single-threaded performance have become out of place for these applications. In early 2005, a series of moves by Intel and AMD made it clear that the processor industry has found a new way to dramatically improve processor performance - the “multi-core processor” in which future processor performance designs From the original pursuit of ILP performance to multi-core processors can release the multi-threaded parallel ability transfer, TLP performance. Currently for Intel and AMD multi-core processor technology solutions have been implemented in the product, and this article to be about “CELL” processor is completely different from another presentation, let’s work together to uncover the mystery of “CELL” Technical veil.
