Suppose the branch frequencies (as percentages of all instructions executed) are as follows: Conditional branches 15% Jumps and calls 5% And assume that 60% of conditional branches are taken. In a certain processor, conditional branches that are taken cause a three cycle stall, conditional branches that are not taken cause a two cycle stall, and jumps and function calls cause a one cycle stall. (a) Assuming that there are no other pipeline stalls, by what fraction do these branch hazards slow this computer
