Wave Generator in C/C# language for generating a MIF file using in Vivado/ISE




//------------------------------------------------------------//
There are 4 major stages:

1st stage: 
1. multiplier_pre: it is uesd to do multiplication in Sin and Cos arm; 
2. NCO: it is a numerical control oscillator as a feedback loop for the multipliers. Both Sin and Cos data are from table.v

2nd stage:
1. fir: it is a 43-tap FIR filters for Sin and Cos arm;

3rd stage:
1. Multiplier_post: it is used to combine both results out of Sin and Cos arm

4th stage:
1. mf: it is a match filter (simply a 500 units shift register to extract pos or neg peak)
2. fifo: it is a FIFO controller with 1k register which is used to function as a buffer so as to detect the specific signals: eofin, Byte, pushByte, Sync, lastByte.
