Lab 9 introduced the use of memory in order to use the data in a text file to run an audio player. I was able to compile the provided circuit and send an audio file over the serial port to the FPGA which played the song. This lab was very useful in demonstrating the use of on board memory in the context of file i/o which is an extremely useful part of any digital circuit that does not do a specific task or needs to access data that is store on an external device like a hard drive.
