In architecture, the term "bubble chart" is also applied to a first architectural sketch of the layout constructed with bubbles. [ 5 ] In software engineering , "bubble chart" can refer to a data flow , a data structure or other diagram in which entities are depicted with circles or bubbles and relationships are represented by links drawn ...
Such an event is often called a bubble, by analogy with an air bubble in a fluid pipe. In some architectures, the execution stage of the pipeline must always be performing an action at every cycle. In that case, the bubble is implemented by feeding NOP ("no operation") instructions to the execution stage, until the bubble is flushed past it.
insert a pipeline bubble whenever a read after write (RAW) dependency is encountered, guaranteed to increase latency, or; use out-of-order execution to potentially prevent the need for pipeline bubbles; use operand forwarding to use data from later stages in the pipeline; In the case of out-of-order execution, the algorithm used can be:
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...

Problem resolved using a bubble A pipeline interlock does not have to be used with any data forwarding, however. The first example of the SUB followed by AND and the second example of LD followed by AND can be solved by stalling the first stage by three cycles until write-back is achieved, and the data in the register file is correct, causing ...
