g. A computer system has a unified level 1 cache (L1). For a given program with 1 million instructions, L1 cache miss rate is 20%. Average instruction execution time is 20ns. For the misses, time to take a block from main memory into L2 cache is 300ns. Calculate the time to execute this program. Give your result in milliseconds. 1.000.000 Instruction L1 Hit Rate =80% Avg Execution Time =20ns h. In the control memory 8 control words are allocated for each execute routine. Execute routines are placed in the second half of the control memory. Opcodes are 6 bits. Design the mapping and write starting address of the routine which has opcode 001011
