存储器配置装置以及方法

Abstract

存储器配置装置以及方法。该存储器配置装置,适用于在集合关联式快取存储器中配置项目,包括:阵列,该阵列根据来自第一功能单元的第一配置请求提供第一PLRU向量。第一PLRU向量从快取存储器的集合指定第一项目,该集合由第一配置请求所指定。第一PLRU向量是包括多层的位树。反转逻辑单元接收第一PLRU向量并反转多个既定位并根据自第二功能单元的第二配置请求以产生第二PLRU向量,而第二配置请求和第一配置请求同时产生,并指定快取存储器的相同集合,而相同集合由第一配置请求所指定。第二PLRU向量指定第二项目,该第二项目有别于来自相同集合的第一项目。既定位包括多层位树的一既定层的所有位。
The invention relates to a memory configuration apparatus and the method thereof. The memory configuration apparatus is suitable for configuring projects in set association type cache memory, and comprises an array which can provide a first RLRU vector according to a first configuration request from a first function unit; the first RLRU assigns a first project from a cache memory set which is assigned by the first configuration request; the first PLRU vector is a bit tree containing a plurality of layers; a reversing logic unit receives the first PLRU vector and reverses a plurality of established bits, and generate a second PLRU vector according to the second configuration request of a second function unit; the second configuration configure request and the first configuration request are generated at the same time; the same set of the cache memory is assigned by the first configuration request; a second project assigned by the second PLRU vector is different from the first project from the same set; and the established bits include all the bits in the multi-layer bit tree.
