CPU cache

The L1/L2 cache hierarchy is designed to store copies of frequently accessed data, reducing the need to access slower main memory. This results in faster data retrieval for the CPU, enhancing overall system performance.

The L1 cache is typically smaller and faster, while the L2 cache is larger but slightly slower. This hierarchical structure allows for efficient data storage and retrieval, balancing speed and capacity.

Modern CPUs use this cache hierarchy to minimize the time spent accessing global memory, leading to improved computational efficiency and reduced latency.
