【摘要】：Flash存儲(chǔ)器常作為嵌入式大屏幕顯示系統(tǒng)的顯示信息存儲(chǔ)設(shè)備,然而Flash存儲(chǔ)器在使用時(shí)會(huì)存在諸如位反轉(zhuǎn)等讀寫操作出錯(cuò)的問題,給系統(tǒng)的正常顯示控制帶來隱患。對(duì)Flash存儲(chǔ)器存儲(chǔ)誤碼率進(jìn)行了分析,并結(jié)合顯示數(shù)據(jù)存取的特點(diǎn),設(shè)計(jì)了差錯(cuò)控制編碼來實(shí)現(xiàn)Flash存儲(chǔ)器下的顯示數(shù)據(jù)差錯(cuò)控制。結(jié)合嵌入式控制系統(tǒng)的特點(diǎn),設(shè)計(jì)了一種基于(31,26)循環(huán)漢明碼編譯碼電路,在實(shí)際應(yīng)用中可以將誤碼率降低至少1個(gè)數(shù)量級(jí)以上,提升了數(shù)據(jù)存儲(chǔ)器抗突發(fā)干擾和隨機(jī)干擾的能力,同時(shí)具有較低的設(shè)計(jì)復(fù)雜度。
[Abstract]:Flash memory is often used as the display information storage device of embedded large screen display system. However, when Flash memory is used, there will be problems such as bit inversion and other reading and writing errors, which will bring hidden trouble to the normal display control of the system.The bit error rate (BER) of Flash memory is analyzed, and the error control coding is designed to realize the error control of display data under Flash memory combined with the characteristics of display data access.According to the characteristics of embedded control system, this paper designs a circuit for encoding and decoding the hamming code based on the X31B26). In practical application, the BER can be reduced by at least one order of magnitude, and the BER can be reduced by more than one order of magnitude.The ability of data memory to resist burst interference and random interference is improved, and the design complexity is low.
