Cpu cache geometry
A 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 … See more When trying to read from or write to a location in the main memory, the processor checks whether the data from that location is already in the cache. If so, the processor will read from or write to the cache instead of … See more Cache row entries usually have the following structure: The data block (cache line) contains the actual data fetched … See more Most general purpose CPUs implement some form of virtual memory. To summarize, either each program running on the machine sees its own simplified address space, which contains code and data for that program only, or all programs run in a common … See more Early examples of CPU caches include the Atlas 2 and the IBM System/360 Model 85 in the 1960s.
