niosII_microc_lab1.vhd demonstrates how to incorporate our/Xilinx's IrDA components into a top level file.
The instantiataion of our custom component, irda_xlinx, is all you will need in your top level. 
Just make sure to send in the proper signals to irrxd(this is the input IR signal from the IrDA).
Also that the clkin is expecting a 50 MHz input clock.
Our component will output a 32-bit decoded command, readdata, from the serial IR signal.
Also note that this component only decodes NEC transmission protocol signals (i.e. a tv remote).
