Ideal case of super pipelining the super pipeline produces the result every tm clock cycle. Afaik, super pipeline was coined to describe systems that had one or more stages of the pipeline running at a higher speed than the rest of the pipeline, typically a small integer multiple like 2. The slowest of this might be the computation part, in which case the overall throughput speed of the instructions through this pipeline is just the speed of the computation part as if the other parts were free. The operation of the instructions is performed in a pipeline fashion, similar to the assembly line. This is a processor design that divides the pipeline up into a large number of small stages. When a functional unit is idle because it is waiting on the currentlyexecuting thread, it can execute an instruction from another thread in the meantime. However, when the stage becomes free it is used to execute the same operation that belongs to the next instruction. Risk assessment for pipelines in deepwater rapid joint.

Unlike other instruction oriented architectures, raw 7 uses a microprocessor as a processing element. In contrast to a superscalar processor, a superpipelined one has split the main computational pipeline into more stages.
Superscalar design involves the processor being able to issue multiple instructions in a single clock, with redundant facilities to execute an instruction. The pipeline organization can be demonstrated by this simple example. Super pipeline is an alternative approach to achieve greater faster performance because many pipeline stages need half a clock cycle meaning that when it execute one instruction it already executing start second instruction and it execute half of the second instruction when first instruction is fully executed.
