-N = input data block size in couple number ranging from 56 to 2396
-f = frequency in Mhz
+N = input data block size in couple number ranging from 56 to 2396.
+f = frequency in Mhz.
 
 For 50 Mhz clock speed and N = 56, throughput equals 31.5 Mbps
 For 50 Mhz clock speed and N = 2396, throughput equals 33.3 Mbps
