History homework help. The following C “optimizations” are said to improve the performance of embedded systems. In reality, some of them are useless or even counterproductive on certain architectures. For each of the “optimizations” given, Find out why it optimizes performance on some architectures Find out if there are any targets on which it does not improve performance, or decreases performance On the architectures on which it improves performance, how great is the improvement? (e.g., one instruction overall, one instruction per iteration of a loop, etc.) Is the improvement significant or trivial? Here are the “optimizations”: (a) Count down to zero, not up to N, in for() loops (b) Avoid the % operation (c) Use an 8-bit unsigned char whenever you have a value that you know won’t go beyond 0-255 (e.g., some loop index variables)
