If a cache hit retrieves a value in 5ns, and retrieving a value from main memory requires 25ns, what is the average effective access time for this cache, assuming that all memory accesses exhibit the same hit rate of 0.8 and assuming the system uses a) A non-overlapped (sequential) access strategy

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
