In contrast, we use pointer-chasing to measure the latency of loading a cacheline by randomly accessing discontinuous

WebThere are typically four levels of memory in a memory hierarchy: Registers: Registers are small, high-speed memory units located in the CPU. They are used to store the most frequently used data and instructions. Registers have the fastest access time and the smallest storage capacity, typically ranging from 16 to 64 bits. http://csg.csail.mit.edu/6.888Yan/slides/review/L15-MemoryHierarchy.pdf
