The CPU of CISC supports non-aligned Data Reading.3.3 example
Let's look at an example:
// Example 1 void test (void) {char a [] = {1, 2, 3, 4, 5}; int * Pi, I; printf (" A [1] = % P/N", A [1]); Pi = (int *) A [1]; I = * PI; printf ("% 08x/N", I );}
The key is:
i = *pi;
We know that the four bytes that the address PI points to are 0x02,0x03,0x04,0x05. On
