Embedded C Interview Questions. Embedded C interview Questions for Embedded Systems Engineers. Q: Which is the best way to write Loops? Q: Is Count Down. When a loop is unrolled, a loop counter needs to be updated less oftenandfewer branches are executed. If the loop iterates only a few times, it can be fully unrolled,so that the loop overhead completely disappears. That isit operates the variable from register, than memory. Generally local variables are allocated in registers. However if we take the address of a local variable, compiler will not allocate the variable to register. Q: How does global variable result in unoptimized code? A: For the same reason as above, compiler will never put the global variable into register. So its bad. Q: So how to overcome this problem? A: When it is necessary to take the address of variables, (for example if they are passed as areference parameter to a function). Make a copy of the variable, and pass the address of that copy. Q: Which is better a char, short or int type for optimization? A: Where possible, it is best to avoid using char and short as local variables.
