Description: Latency hiding is a set of techniques used in microprocessors to mask the latency associated with memory accesses. This latency refers to the time that elapses from when a data request is made until it is received, which can significantly affect system performance. To mitigate this issue, microprocessors implement various strategies that allow other operations to be performed while waiting for the memory response. Among these techniques are out-of-order execution, where instructions are processed in an order different from that in which they were issued, and the use of buffers that temporarily store data. These methodologies not only improve the efficiency of processor usage but also optimize data flow, allowing execution units to continue working without interruptions. Latency hiding is essential in modern microprocessor architecture, as it maximizes performance and minimizes downtime, resulting in a smoother experience for the end user.
