If the CPU needs data or instructions, how is that need satisfied using cache and the memory hierarchy?

Answer #1

Answer)

Many CPU's in modern times are working faster due to the cache memory that is lowering the program workload. There is a locality of reference present in the memory for accessing the memory which enhances the caching efficiency and also helps in transferring the memory among many other levels of the hierarchy in the memory. Hence the CPU doesn't spend much of its time in waiting for the I/O or fetching information but gets this information from the cache and this is fast and convenient for regular use. The pressure and lead time are less when trying to access any data which was recently or frequently accessed.

A CPU is trying to transfer 16 KB of data in burst mode from its memory to the external memory through a 32-bit bus. Compute the time required for the transfer, if the clock cycles per burst is 2 and the number of bursts for the entire transfer is 16. Assume the bus runs at 10 MHz and has an overhead of 32 clock cycles. How much data can be burst transferred from the external memory in 5 ms?
