Solve part C.
For the system shown below, answer following questions CLK DATA BUS (16 bits) 3.3GHZ CPU ADDRESS BUS (23 bits) RAM READ SIGNAL WRITE SIGNAL a. Find the maximum size of RAM in bytes to be used?. b. If CPI of LOAD/STORE is 6, find the time (in second) to read a 1-byte data from RAM. Also find the time to store 4-bytes to RAM c. A program contains 100 instructions each of 4-bytes and an instruction fetch requires 4 clock cycles. Moreover, 40% instructions are LOAD/STORE having CPI of 6. i. Number of memory accesses to run the program. ii. Calculate execution time, iii. Calculate MIPS rating of the systen d. If a unified cache is used having 90% hit rate and access time of 2 clock cycles, calculate execution time and MIPS rating of the system
