This is MP3 decoder for OpenRISC configured for the xess board.

Make the mp3 player with:

    ./makes2 songs/Beethoven-fuer_elise-16.mp3 songs/Moonlight-16.mp3

This should build mp3 decoder for or32 and also put these two

songs in the memory image.

You get three outputs:

- minimad : this is executable in COFF binary format that you can use

on the simulator (type "sim  minimad", uncomment the OR1K_SIM define

in config.h to get PCM output in a file audiosim.pcm, which you can hear

using command "play -t raw -r 22050 -s w -f s -c 2 audiosim.pcm")

- minimad.s2 : this is srecord siutable to be merged with bitstream (*.exo)

that is burned into flash memory in xess board

(type "../utils/merge2srec xfpga_top.exo minimad.s2" to get out.exo and then

load this to xess board)

- minimad.mem : this file is used to initialize flash model for the RTL

simulation (sim/ncsim/run/run_sim is expecting this file so you have to

build this decoder before you run the simulation).
