The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.
delay to access the data in cache in context of processor's speed. Time to access the requested data in cache , at that time processor have to wait .. is called cache latency.
Not the same.
miss latency is the time (in cycles) the CPU waits when a miss happen in the cache. (the time needed to bring the data from the main memory to the cache).
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
L3 Cache
L3 cache
L3 cache
L1, L2, and L3
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
L3 cache is located on the motherboard or in CPU housing.Hope this help.
It uses L1 L2 and L3.
