In a pipelined processor, when an instruction needs the result of a previous instruction that has not yet finished its execution, what specific type of hazard occurs?



When an instruction in a pipelined processor needs the result of a previous instruction that has not yet finished its execution, a Data Hazard occurs. This specific type of data hazard is known as a Read-After-Write (RAW) dependency, also referred to as a true data dependency. A pipelined processor breaks down the execution of an instruction into several stages, such as Fetch, Decode, Execute, Memory Access, and Write-Back. It processes multiple instructions concurrently, with each instruction in a different stage, much like an assembly line. This overlapping execution improves the processor's throughput. A hazard is any sit....
