摘要：在嵌入式系統(tǒng)中，Nor Flash和Nand Flash是目前市場上主要的主要的非易失閃存的存儲(chǔ)器。Nor Flash存儲(chǔ)器的容量小、寫入速度較慢，但因其隨機(jī)讀取速度快，因此在嵌入式系統(tǒng)中，常用于程序代碼的直接存儲(chǔ)。與Nor相比，Nand閃存的優(yōu)點(diǎn)是容量大、寫入速度快，成為了嵌入式產(chǎn)品中主要的數(shù)據(jù)存儲(chǔ)設(shè)備。而且Nand Flash這種低功耗、小體積以及低成本的存儲(chǔ)設(shè)備已經(jīng)得到了廣泛的應(yīng)用。本課題深入研究了MTD的設(shè)計(jì)原理和架構(gòu)，通過對(duì)Flash設(shè)備的驅(qū)動(dòng)學(xué)習(xí)，在Linux系統(tǒng)下對(duì)Nor Flash和Nand Flash進(jìn)行驅(qū)動(dòng)的編寫，從而實(shí)現(xiàn)Flash設(shè)備的基本運(yùn)用。 關(guān)鍵詞：嵌入式 Nand Flash 驅(qū)動(dòng)程序
Abstract：of Nor Flash and Nand Flash is currently on the market of the main non-volatile flash memory in embedded systems. Nor Flash memory capacity is small, slow write speed, but because of its random read speed in embedded systems, commonly used in the program code stored directly. Compared with Nor, of Nand flash memory has the advantage of large capacity, fast write speed, has become the main data storage devices in embedded products. Nand Flash This low power consumption, small size and low-cost storage devices has been widely used. This topic in-depth study of design principles and architecture of the MTD, Nor Flash and Nand Flash drive the preparation of learning Flash device driver in the Linux system, in order to achieve the basic use of the Flash device. Key words: Embedded Nand Flash Driver |
