MP3的verilog硬件实现_完整工程

MAC_MP3: A Low Energy Implementation of an Audio Decoder Copyright (C) 2007 McMaster University =============================================================================== DE2_SD_Card_MP3 --------------------- This designs uses a Nios II system to demonstrate how to read from the SD card. The software reads MP3 files from the SD card, decode it using the MP3 hardware core, and plays it through the LINE OUT line. Software versions --------------------- This project is developed using Altera Quartus II version 5.0 build 148 04/26/2005 SJ Full Version and NIOS II IDE version 5.0 build 73c. The authors do not guarantee compatibility between software versions. Preparing the SD card --------------------- To prepare the SD card for reading by the design, it should be formatted using a FAT16 file system. Then MP3 files can be copied on to the card. Note that if you want to add a file after you've removed the card from the computer, you must reformat the card first and then re-add the files. Compiling the Design --------------------- 1) Launch the Quartus II software. 2) Open the DE2_SD_Card_Audio.qpf project located in the <install path>\DE2_SD_Card_MP3 folder. (File menu -> Open Project) 3) Start compilation. (Processing -> Start Compilation) 4) After compilation is finished, you can run the design with the generated SOF file. See 'Running the Design' below, which includes steps to build the Nios II project for details. Running the Design --------------------- 1) Launch the Quartus II software. 2) Open the DE2_SD_Card_Audio.qpf project located in the <install path>\DE2_SD_Card_MP3 folder. (File menu -> Open Project) 3) Open the Programmer window. (Tools menu -> Programmer) 4) The DE2_SD_Card_Audio.sof programming file should be listed. Check the 'Program/Configure' box and set up the JTAG programming hardware connection via the 'Hardware Setup' button. 5) Press 'Start' to start programming. The design should now be programmed. 6) Launch the Nios II IDE. 7) Switch the workspace to the <install path>\DE2_SD_Card_MP3 folder. 8) Import the project DE2_SD_MP3 to Nios II IDE. 9) Import the library DE2_SD_MP3_syslib to Nios II IDE. 10) Change the project target in the system.stf file for DE2_SD_MP3_syslib to "<install path>\DE2_SD_Card_MP3\nios_0.ptf". 10) Set compile option for DE2_SD_MP3 to Release 11) Right click on DE2_SD_MP3, select run as hardware =============================================================================== COPYRIGHT AND AUTHORS Please read the `LICENSE.txt' file for copyright and warranty information.
