CPU cache: History & Measurement

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 memory locations, avoiding the need to always refer to…

How CPU cache connects Entity context

The extracted context around CPU cache shows recurring relationship patterns in the source. For example, CPU cache → April, ARMv5TE, Atlas, Caches, CPU, CPUs, DRAM, Duo, Every, Historically L1, IBM, IBM System/360 Model, Intel Atom CPUs, Intel Core, Intel Ice Lake-based, KiB, KiB L1, L1, L1d, L1i Another extracted example is CPU cache → CPU, Higher, RAM, SRAM. Use these groups to spot repeated connection types before inspecting the individual relationships.
