介绍基于FPGA的嵌入式系统实现MP3编码。该系统的编码程序和指令在嵌入式系统的外部存储器DDR SDRAM中存储,片内只读存储器(ROM)将PCM码流输出到Micro Blaze处理器进行编码,编码后的MP3码流通过串口传送到PC机上,PC机上的客户端程序将码流写入.mp3文件。为达到该目标,先后完成PCB的绘制、系统的开发和调试,以及客户端程序的编写,经测试后,达到预期目标。 Introduce the embedded system based on FPGA to realize MP3 coding. The system’s encoding program and instructions in the embedded system’s external memory DDR SDRAM storage, on-chip read-only memory (ROM) PCM stream output to the Micro Blaze processor for encoding, encoded MP3 code stream through the serial port to On the PC, the client program on the PC writes the code stream to the .mp3 file. To achieve this goal, has completed the PCB drawing, system development and debugging, as well as the preparation of the client program, after testing, to achieve the desired goal.
