Based on uC / OS II MP3 document broadcast system design_ucos, mp3
Wednesday, December 9th, 2009 at 19:07 | No commentsCategories: Embedded systemShort Content: 1 introduction In recent years, the MP3 audio frequency product receives consumer's favor, but the high grade sound effect is the current MP3 audio frequency product development important tendency. The MP3 document decoding uses the software decoding and the hardware generally decodes two methods. The hardware decoding realizes simply, but must increase the hardware cost. The software decoding must take the massive CPU time, realizes the difficulty to be big, but the cost is low, processing is flexible, so ... -
Based on ARM9 multi-purpose hard disk MP3 player design_ARM, ARM9, mp3
Monday, October 19th, 2009 at 04:01 | No commentsCategories: Embedded systemShort Content: Defines an accurate name very difficultly for this design proposal, is the hard disk MP3 player, digital camera companion, is the electronic picture frame, even is called the motion hard disk? Actually these function this section of design proposal had. However usual, takes the MP3 use the frequency to be higher some, therefore we are called as for the time being it the multi-purpose hard disk MP3 player. This section of multi-purpose MP3 player's core is the Tristar ... -
