Execution time

Some examples

In this section, we assume that variables a, b, and c are of type integers, and variables x, y and z are of type double.

Table 1 Comparison of execution time of various calculations across different platforms.

Instruction	C++ CPU	L476RG	G431KB
no operation	/		~26 ns
out_pin = 1;	/		~22 ns
c = a + b;			< 50 ns
c = a * a;			< 50 ns
c = pow(a, 2);			~6.5 us
z = x + y;
