摘要： 针对以闪存为存储介质的存储器设计参数化的实时RS编译码策略，能够适应不同的图像分辨率。给出完整的具有RS编译码的记录系统存储和读出方案，解决闪存数据翻转时系统的可靠存储问题，提高系统的可靠性，实时检纠错效果比较好，每个RS过程可纠正 3个字节随机错误。在640×480像素的图像分辨率下，最大页纠错能力达72字节，信噪比提高2 dB以上。

Abstract: In consideration of the memorizer which uses the flash memory as storage media, this paper proposes a RS algorithm to adapt to different resolutions, and a package of comprehensive approach is designed which has the full ability of recording storage and reading of the system. It solves the problem of lacking the reliable when the data in flash memory is rotating, and improve the quality of the system. Each process can remedy 3 Byte random errors, under the condition of 640×480 pixel, the maximum by page of correcting errors is up to 72 Byte, signal-to-noise ratio increases by more than 2 dB.

Key words: flash memory, RS code, self-adaptive, error detection, error correction
