【摘要】：很多優(yōu)化處理器緩存利用效率的方法依賴于對(duì)訪問(wèn)請(qǐng)求序列的特征的探測(cè)或識(shí)別,例如,預(yù)取和繞開(kāi)等。如何在線有效識(shí)別訪問(wèn)請(qǐng)求序列的特征依然是一個(gè)開(kāi)放的問(wèn)題。通過(guò)對(duì)典型訪問(wèn)模式的深入分析,發(fā)現(xiàn)其堆棧距離頻度的分布展示出鮮明的特征。而模擬實(shí)驗(yàn)數(shù)據(jù)表明訪問(wèn)請(qǐng)求序列的特征具有一定的持續(xù)性和穩(wěn)定性,具有檢測(cè)和預(yù)測(cè)的可行性。因而提出了一種基于堆棧直方圖峰值的在線識(shí)別訪問(wèn)模式的機(jī)制和方法,空間和時(shí)間開(kāi)銷都較小。對(duì)SPEC CPU2000/2006的15個(gè)程序的實(shí)驗(yàn)表明,所提方法均可正確識(shí)別測(cè)試程序的訪問(wèn)模式。
[Abstract]:Many methods to optimize the efficiency of processor cache utilization depend on the detection or recognition of the features of access request sequences, such as prefetching and bypassing. How to effectively identify the features of access request sequences is still an open problem. Through in-depth analysis of typical access patterns, it is found that the distribution of stack distance frequency shows distinct characteristics. The simulation results show that the characteristics of access request sequences are consistent and stable, and have the feasibility of detection and prediction. Therefore, a mechanism and method for on-line identification of access patterns based on stack histogram peak is proposed, with less space and time overhead. Experiments on 15 programs of SPEC CPU2000/2006 show that the proposed method can correctly identify the access patterns of test programs.
