摘要
磁带式复读机日趋淘汰,便携式Mp3播放器的“A-B”复读功能操作复杂,不实用。针对现有产品的不足,采用Flash芯片作为数据存储器,以第二代数字MCU为处理器,利用日益完善的DSP技术,编写嵌入式软件,从而研制出随身Flash语言复读机。具有一键复读、跟读、对比复读、LRC文字显示等先进的语言学习功能。
The audio tape replayer is becoming obsolete .The A-B section repeat of the pocketable Mp3 player is too complicated to operate. It is impractical in practice! To remedy the elder replayer＇s defect directly, it is necessary for us to design the pocketable language learning replayer composed of flash memory and second generation digital MCU , by use of DSP technology that approximate perfected, through writing embedded software. The replayer have the advanced features as one key replay, repeating after replay ,replay and repeating across ,display the LRC words on OLED, and so on.
