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

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
