描述

主存儲(chǔ)器(Main memory)，簡(jiǎn)稱主存。是計(jì)算機(jī)硬件的一個(gè)重要部件，其作用是存放指令和數(shù)據(jù)，并能由中央處理器(CPU)直接隨機(jī)存取?，F(xiàn)代計(jì)算機(jī)是為了提高性能，又能兼顧合理的造價(jià),往往采用多級(jí)存儲(chǔ)體系。即由存儲(chǔ)容量小，存取速度高的高速緩沖存儲(chǔ)器，存儲(chǔ)容量和存取速度適中的主存儲(chǔ)器是必不可少的。主存儲(chǔ)器是按地址存放信息的，存取速度-般與地址無關(guān)。32位(比特)的地址最大能表達(dá)4GB的存儲(chǔ)器地址。這對(duì)多數(shù)應(yīng)用已經(jīng)足夠，但對(duì)于某些特大運(yùn)算量的應(yīng)用和特大型數(shù)據(jù)庫已顯得不夠，從而對(duì)64位結(jié)構(gòu)提出需求。

Main memory, abbreviated as main memory. It is an important component of computer hardware that stores instructions and data, and can be directly accessed randomly by the central processing unit (CPU). Modern computers often use multi-level storage systems to improve performance while also considering reasonable costs. A cache memory with small storage capacity and high access speed, as well as a main memory with moderate storage capacity and access speed, are essential. The main memory stores information by address, and the access speed is generally independent of the address. A 32-bit address can represent up to 4GB of memory address. This is sufficient for most applications, but it is no longer sufficient for some applications with large computational complexity and large databases, thus requiring a 64 bit architecture
