A uniprocessor has an L1 and an L2 cache. With no cache misses, the processor achieves an average CPI of 1. Suppose that in reality an L1 miss occurs every 50 instructions executed and that an L2 miss occurs every 500 instructions executed. The L1 miss penalty is 40 cycles and the L2 miss penalty is 400 cycles. The L2 cache is referenced only after a miss in the L1 cache. What is the effective (i. e., average) CPI rating for the processor with these cache miss rates

Elements such as fonts colors visual structure graphics and the interface of a web page should complement each other to ensure blank

Which of the following statements is false? a. a class can directly inherit from class object. b. if the class you're inheriting from declares instance variables as private, the inherited class can access those instance variables directly. c. a class's instance variables are normally declared private to enforce good software engineering. d. it's often much more efficient to create a class by inheriting from a similar class than to create the class by writing every line of code the new class requires.
