"Web30 jan. 2024 · In its most basic terms, the data flows from the RAM to the L3 cache, then the L2, and finally, L1. When the processor is looking for data to carry out an operation, it first tries to find it in the L1 cache. If the CPU finds it, the condition is called a cache hit. It then proceeds to find it in L2 and then L3. " - Memory hierarchy in a computer

Web27 nov. 2024 · random access memory. Whether it comes from permanent storage (the hard drive) or input (the keyboard), most data goes in random access memory (RAM) first. The CPU then stores pieces of data it will need to access, often in a cache, and maintains certain special instructions in the register. WebA CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.Most CPUs have …
