  1. 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結構具有六個突出優勢：相對于大規模的超標量結構而言， smpdca結構的控制邏輯復雜性明顯要低得多；相對于通過共享主存來實現處理器之間的通信的結構而言，通過一個共享的第一級數據cache來實現處理器之間的通信的smpdca結構能夠提供非常小的處理器之間的通信延遲；沒有cache一致性維護開銷；數據cache命中率提高；便於smp （對稱多處理器結構）的軟體重用；從多個層次上開發程序的并行性。
  2. Reorders faces to increase the cache hit rate of vertex caches

    對面重新排序，以增加頂點高速緩存的高速緩存命中率。
  3. We test the experimentation system by fixed - quanity emu1ation with standard data, and the performance ana1ysis indicates that when the size of circulatory prograxn seginent is smaller than the cache size, the cache hit rate is higher than 90 %, while bigger than the cache size, the hit rate is between 48 % and 74 %

    本文詳細論述了定義cache工作的類mesi協議，針對實驗儀的結構，給出了cache的設計原理圖和電路圖。用典型數據定量模擬測試，分析性能，結果證明，循環的程序段容量小於cache時， cache命中率高於90 ；大於cache時， cache命中率在48 - 74之間。
  4. This algorithm can improve hit rate on backend servers " main memory cache, thus increase the performance of the whole cluster system

    該演算法可提高後端服務器的主存cache命中率，從而提高了整個集群系統的性能。
  5. And then, it gives some useful approaches of program transformation to reduce cache conflicts, and concludes three accessing modes in multi - media applications to prepare for the further study of stream cache prefetching technologies. this paper also introduces a data allocation approach to scratch - pad sram, with the purpose of improving cache hit rate

    討論了常用的提高數據時空局部性的程序變換方法以降低cache失效率，並針對多媒體領域應用程序的特點，總結了三種多媒體常見存儲訪問模式，為進一步研究並向dpc存儲系統加入流cache的預取技術奠定了基礎。
  6. This paper made performance simulations of spmdca in detail using rsim simulator. this paper present and analyzed four kinds of simulation results : hit rate of data cache, and cost of communications, and affections to the performance due to the long latency of shared data cache, and execution time of applications

    本文利用模擬器rsim對smpdca結構進行了詳細的性能模擬分析，從數據cache命中率、通信開銷、共享數據cache的訪問延遲對性能的影響以及程序執行時間四個方面給出了模擬結果，並對模擬結果進行了分析。
