4. A certain optical jukebox can store 150 PB. Express this in terms of bytes.

5. Assume the cache in Figure 10?3 has a latency of 30 ns and the main memory a latency of 75 ns. Determine the time required for the processor to acquire a block of data for a cache hit and for a cache miss as illustrated in the figure.

6. Define the terms temporal locality and spatial locality.

14. Redraw the block diagram in Figure 10?15 for a 64k * 8 memory.

17. For the ROM array in Figure 10?75, determine the outputs for all possible input combinations, and summarize them in tabular form (Blue cell is a 1, gray cell is a 0).

24. Using a block diagram, show how 64k * 1 dynamic RAMs can be expanded to build a 256k * 4 RAM.

27. Consider a 4096 * 8 RAM in which the last 64 addresses are used as a LIFO stack. If the first address in the RAM is 00016, designate the 64 addresses used for the stack

SOLUTION.
1. A memory cache is also called a cache store or RAM cache.
A cache refers to a portion of the memory formed of highest speed static Random Access
Memory (SRAM)
It?s located on a...
