How to make a recording

1. Load the bitstream -- start xps and open the system.xmp file in the "ML507_PCIe_MEM_Project" directory. Choose "download bitstream" from the "Device Configuration" menu.
2. Restart the computer
3. Go into the "src" directory and do:
   1. >> sudo make clean
   2. >> sudo make
   3. >> sudo make load
   4. >> sudo make read
4. Now there should be an executable "Bram" made. Running "sudo ./Bram" will cause a microphone recording for about 10 seconds. The result should be placed in a file "MEM.txt".
5. Move MEM.txt into the "matlab" directory and run "DeltaSigma.m" in matlab to decode the recorded bitstream.
