For a system, RAM = 64KB, Block size = 4 bytes, Cache size = 128 bytes, Direct mapped cache. Function NSU-1 Calculate the Hit ratio while CPU runs program "Test Cache". Also count how many blocks are replaced in cache memory assuming the cache is empty at the beginning. Memory address (decimal) 0136 Instruction-1 For the same RAM, block size and Cache memory, what would be the Hit ration in case of Fully Associative Mapping? 0137 Instruction-2 0138 Instruction-3 For the same RAM, block size and Cache memory, what would be the Hit ration in case of 4-way Set Associative Mapping? 0139 Instruction-4 (return to Instruction-8 of main program --- Test Cache) Main Program-"Test Cache" Memory address (decimal) ---- Function NSU-2 0003 Instruction-1 Memory address (decimal) 0004 Instruction-2 0128 Instruction-1 0005 Instruction-3 (Call Function NSU-2) 0129 Instruction-2 0006 Instruction-4 0130 Instruction-3 0007 Instruction-7 (Call Function NSU-1) 0131 Instruction-4 0008 Instruction-8 0132 Instruction-5 0009 Instruction-9 (End of program) 0133 Instruction-6 (return to Instruction-4 of main program--- Test Cache)
