A program consists of a large number of instructions with the following mix 40%ALU 10% store 20% load (of which 60% have values used in the next instruction) 20% branch (determined in the ID stage. taken 40% of the lime and no prediction is done) 0% jump (determined in the ID stage) For the pipelined CPU, what is the formula to determine the actual CPI based on those numbers? A. 40% (1) + 10% (1) + 20%(50%)(2) + 20%(40%(2) + 10%(2) B. 40%(1) + 10%(1) + 20%(1) + 20%(2) + 10%(2) C. 40%(1) + 10%(1) + 20%(50%)(1) + 20%(50%)(2) + 20%(60%)(2) + 20%(40%)(1) + 10%(2) D 40%(1) + 10%(1) + 20%(50%)(1) + 20%(50%)(2) + 20%(40%)(2) + 20%(60%)(1) + 10%(2) The following code is supposed to set St0 to 3 = 0. There is an instruction what is the missing instruction? > beq 5t1, $0 Skip ori $t0, $0, 3} end
