For the I semester of 2012 EDA large operations, including design documentation and source code. The designed system is difficult to find online (at that time I did not find, in particular, is the source), two systems but also has a certain practicality, as long as different songs stored in the ROM code, you can play a different song. Article details " function with automatic music playing piano," the FPGA design principles and methods, the use of ROM storage notes and beats, matrix keyboard to control the entire system. Source notes clear and easy to understand. Welcome to my blog: http://blog.csdn.net/enjoyyl
