K9F1208U0M 的ALE、CLE分別由DSP 的A1 和A0 控制。DSP的低8位數據線直接與閃存的I/O0-I/O7 相連,實現命令、地址和數據的傳輸; DSP的通用I/O口IOA2 接R/B,監測存儲器的工作狀態,當R/ B 處于低電平時,表示有編程、擦除或隨機讀操作正在進行;操作完成后, R/ B 會自動返回高電平。DSP的W E 、R D 分別接FLASH的W E 、R E , 控制讀、寫操作。CS2接閃存的片選線CE。
The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra-
group similarity while minimizing the inter-group similarity.
The first and foremost question needed to be considered in clustering
W b sessions is how to measure the similarity between Web
sessions.However.there are many shortcomings in traditiona1
measurements.This paper introduces a new method for measuring
similarities between Web pages that takes into account not only the
URL but also the viewing time of the visited web page.Yhen we
give a new method to measure the similarity of Web sessions using
sequence alignment and the similarity of W eb page access in detail
Experiments have proved that our method is valid and e幣cient.
