For modern CPUs, the performance bottleneck is access to memory. CPU speeds are often at least two orders of magnitude higher than main memory. So the CPU has introduced L1_cache and L2_cache, and the higher-end CPUs have joined the L3_cache. Obviously, this technique raises the next question:If the memory that a CPU needs to access at the time of execution is not in the cache, the CPU must be taken from the memory bus to main storage, so what happens
