Final answer:
Some instructions, such as loading a register from memory, have unavoidable delays in execution. To preserve the correct execution pattern, added hardware called a pipeline is required.
Step-by-step explanation:
Some instructions, such as loading a register from memory, have unavoidable delays in execution. To preserve the correct execution pattern, added hardware called a pipeline is required.
A pipeline is a hardware mechanism used in computer processors to overlap the execution of multiple instructions. It divides the instruction execution into smaller stages, allowing multiple instructions to be executed simultaneously
.
For example, in a pipeline, while one instruction is being fetched from memory, another instruction can be decoded, and yet another can be executed. This overlap improves the overall performance and efficiency of the processor.
