Description  :  This function tests _conv2d3x3_gen with 4 test cases and finds 
                cycle count for input sizes of 3x3, 5x5, 5x7 and 16x16.
    1. Test1 - Random test with output not overflowing i/p = 3 x 3
    2. Test2 - Random test with output not overflowing i/p = 5 x 5
    3. Test3 - Random test with output overflowing(saturated) i/p = 5 x 5
    4. Test4 - Random test with output not overflowing i/p = 16 x 16
