Consider a three level memory hierarchy with following specifications: Memory level

Consider a three level memory hierarchy with following specifications: Memory level Access Time Capacity Cache t1 =25 ns s1=512 KB Main memory t2=unknown $2=32 MB Disk array t3= 4 ms s3=unknown Cost/Kbyte cl=S 1.25 c2=$0.2 c3=$0.0002 Design the memory hierarchy to achieve an effective memory access time t=10.04us with cache hit ratios h1=0.98 and a hit ratio h2=0.9 in the main memory. Also limit the total cost of the memory hierarchy is upper bounded by $15,000
