The difference between static pipeline and dynamic pipeline

This is classified according to the connection mode of each segment at the same time . Static pipeline refers to , Same as In a moment , Each section of the pipeline can only work according to the connection mode of the same function . The above example ASC Of 8 Segment belongs to static pipeline , Only addition and subtraction or definite multiplication can be performed . So in static pipeline , Only when the input is a series of the same operation , The efficiency of running water can be brought into play . Dynamic pipeline refers to , At the same time , Some segments are implementing some kind of operation （ Such as fixed multiplication ） While other segments are implementing another operation （ Floating point addition ）. In this way, different types of operations can also be pipelined . However, the requirements of dynamic pipeline for control are very high . At present, the vast majority of pipelines are static pipelines .
From the space-time diagram of static and dynamic pipelines given in the figure below , You can clearly see the difference between the two flow methods .

According to whether it can be connected in multiple ways at the same time , Perform multiple functions at the same time , Multi function pipeline can be divided into static pipeline and Dynamic pipeline .

Only when the same operation occurs continuously , The efficiency of the assembly line can be brought into full play . Its advantage is simple control , The disadvantage is that the operation efficiency is not high .

Static pipeline technology is only used to realize certain functions , The pipeline can be recombined dynamically at different times , Realize different functions , In addition to streamline connection , It also allows feedforward and feedback connections , Therefore, it is also called nonlinear pipeline
