A 7.80-9 bullet moving at 575 m/s strikes the hand of a superhero, causing the hand to move 5.50 cm in the direction of the bullet's velocity before stopping. (a) Use work and energy considerations to find the average force that stops the bullet. (b) Assuming the force is constant, de- termine how much time elapses between the moment the bullet strikes the hand and the moment it stops moving. 待回答 回答數: 0

工程與科技 大學 3年以上以前 [計算機組織] 請問這題的 b. 小題 不同的 processor 不是影響 CPI 的值嗎 為什麼可以拿 a. 算出來的 CPI 直接套在這題? 1.7 [15] Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1.0E9 and has an execution time of 1.1 s, while compiler B results in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s. a. Find the average CPI for each program given that the processor has a clock cycle time of 1 ns. CPI = cycles per instruction 1.1 x 10 cycles for 1.0 x 10° instructions => CPL = 1.1 1.5 X 109 cycles for 1.2 x 109 instructions => CPI = 1.25 b. Assume the compiled programs run on two different processors. If the execution times on the two processors are the same, how much faster is the clock of the processor running compiler A's code versus the clock of the processor running compiler B's code? Execution time = CPI x IC x Cycle Time CPIA X ICA X CTP1 = CP1g x IC3 x CT22 CT P:/CTP2 = (CPIE x ICB)/(CPIA X ICA) = (1.25 X 1.2 x 10°)/(1.1. X 1.0 x 10°) = 1.36 Cycle time P1 = 1.36 x Cycle time P2 => P1 is 36% slower than P2 待回答 回答數: 0
