It refers to the process of arranging the execution of commands in a way that overlaps different stages of instruction execution. This technique, when applied to cache memory, involves breaking the cache access process into several stages, allowing multiple instructions or data accesses to be in different stages of execution simultaneously.

In a pipelined cache, these stages work concurrently, similar to an assembly line in manufacturing. While one instruction is being decoded, another can be fetched, and yet another can be executed, leading to a significant increase in throughput. This parallel processing allows for faster overall execution as the delay caused by sequential execution is reduced.

Cache pipelining breaks down the cache operation into several stages, each of which can be executed in parallel with the others. The most common stages are:

For example, if a later operation needs data that is currently being written by an earlier operation, it must wait, causing a stall in the pipeline.
