I need the answer as soon as possible A cache block has 64 kbyte. The main memoryhas latency 64 usec and bandwidth 1 GBps.What is the total time required to fetch the entirecache block from the main memory (in usec,1 G = 109)?

For a 1 GBps bandwidth, loading 109 bytes on line takes 1 second, so 64 bytes will take 64*1/109=64…
