最近出现的第二代RISC处理器在系统设计上具有一定的相似性.象Motorola的88110、Intel的N11或i860XP,它们都有大的片内数据和指令高速缓冲存贮器(cache)以及用于多处理的硬件链(如多执行单元),它们也都有三维绘图能力.除了相似的一面,i86XP有一个质的变化,而超大规模的88110则意味着在结构方面有一个大的飞跃。为了弄清这两家处理器的区别,就有必要剖析每一种结构的并行处理机制——如近似(coarse)、媒体(medium)和粒度(fine- The second-generation RISC processors that have emerged lately have some similarities in system design. Like the Motorola 88110, Intel’s N11 or i860XP, which have large on-chip data and instruction caches, In multiprocessing hardware chains (such as multi-execution units), they also have three-dimensional graphics capabilities. Except for the similar side, the i86XP has a qualitative change, while the ultra-large 88110 means a big leap in structure. In order to understand the difference between the two processors, it is necessary to parse the parallel processing mechanisms of each structure - such as coarse, medium and fine-
