K210 basic benchmark test

I have did a basic computational performance test for K210. Because K210 firmware has no time module now, I have to using my watch to recording time. Integer addition def int_add_test(n=1000000, a = 1234, b = 5678): sum = 0 for i in range(n): sum = a + b It is about 3s when n=1,000,000, and about 29...
