Calculate the global and local miss rates for a 2-level cache. Consider level-1 cache with 16KB and vary the level-2 cache size form 2KB, 8KB, 32KB and 128KB for a block size of 16bytes, LRU replacement policy and 2-way associativity. Compare this value with the miss rates of single-level cache. a) Consider only data caches for simulation and plot the results (Logarithmic scale makes the plot clearer). b) What conclusion can you draw from this? c) Is the local miss rate a good measure of secondary caches? d) What is the optimum value of the secondary cache size?

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student. java, undergraduatestudent. java, graduatestudent. java, studentatlarge. java, and studentdemo. java.
