How can data hazards in a pipeline be mitigated to ensure efficient processing of data?

Data hazards in a pipeline can be mitigated by using techniques such as forwarding, stalling, and reordering instructions. Forwarding allows data to be passed directly from one stage of the pipeline to another, reducing the need to wait for data to be written back to memory. Stalling involves temporarily stopping the pipeline to resolve hazards, while instruction reordering rearranges the order of instructions to avoid data dependencies. These techniques help ensure efficient processing of data in a pipeline.
