对称多处理器 meaning in English
symmetric maltiple processor
Examples
- Web servers are typically low - end to midrange systems with up to 4 - way symmetric multiple processors ; enterprise - level systems have more complex requirements , such as larger processor counts and i o configurations and significant memory and bandwidth requirements
这些web服务器通常是低端及位于中间档次的系统，带有最多可达4路的对称多处理器（ smp ） ；而企业级系统有更复杂的需求，譬如需要更多的处理器个数和i / o配置以及大的内存和带宽。 - Smpdca architecture has six outstanding excellences : complexity of the control logics of smpdca is lower than large scale superscalar ; supplying shortest inter - processor communication latency using the shared li data cache ; no cost to maintain cache coherence ; hit rate of data cache increase ; easy to reuse many softwares of symmetric multiprocessor ( smp ) ; exploit the parallelism of applications from many levels . this paper present the architecture model of smpdca , and illustrated its function units , and discussed its key techniques , and analyzed the address image policy of multi - ported cache
Smpdca结构具有六个突出优势：相对于大规模的超标量结构而言， smpdca结构的控制逻辑复杂性明显要低得多；相对于通过共享主存来实现处理器之间的通信的结构而言，通过一个共享的第一级数据cache来实现处理器之间的通信的smpdca结构能够提供非常小的处理器之间的通信延迟；没有cache一致性维护开销；数据cache命中率提高；便于smp (对称多处理器结构)的软件重用；从多个层次上开发程序的并行性。
