The easiest solution is to stall the pipeline. We could delay the AND instruction by introducing a one-cycle delay into the pipeline, sometimes called a bubble.
Types of Pipeline Delay and Stalling - Javatpoint
With the help of implementation of branch predication, the pipeline stall can be resolved. The potential of pipeline stall is determined by the downside of RISC processor. When a user executes several functions at the same time, in this case, the pipeline stalls will occur. 1. …
Pipeline stall - Wikipedia
In the design of pipelined computer processors, a pipeline stall is a delay in execution of an instruction in order to resolve a hazard. [1] In a standard five-stage pipeline, during the decoding stage, the control unit will determine whether the decoded instruction reads from a register to which the currently executed instruction writes.
Pipelining, Pipeline Stalls, and Operand Forwarding
The CPU hence can't execute these instructions until their data is ready, and so the CPU must detect these dependencies (also called "pipeline interlocks") and insert waste "stall cycles" or ("pipeline bubbles") to wait for the needed data.

Sep 13, 2024 · Pipelining is a technique used in modern processors to improve performance by executing multiple instructions simultaneously. It breaks down the execution of instructions into several stages, where each stage completes a part of the instruction.

Apr 11, 2023 · Stall : A stall is a cycle in the pipeline without new input. Structural dependency This dependency arises due to the resource conflict in the pipeline. A resource conflict is a situation when more than one instruction tries to access the same resource in the same cycle.

The simplest way to handle these hazards is to stall the pipeline. Stalling of the pipeline allows few instructions to proceed to completion while stopping the execution of those which results in hazards.
Pipeline must stall until hazard cleared (starting with instruction that wants to use data until source produces it). Can’t get data to subtract b/c result needed at beginning of CC #4, but not produced until end of CC #4. Send output of memory back to ALU too...
Stalls and performance • Stalls impede progress of a pipeline and result in deviation from 1 instruction executing/clock cycle • Pipelining can be viewed to: –Decrease CPI or clock cycle time for instruction –Let’s see what affect stalls have on CPI… • CPI pipelined = –Ideal CPI + Pipeline stall cycles per instruction
Pipelining essentially involves creating an assembly line for instruction execution. Each step in the pipeline is called a stage. Multiple instructions can be processed in parallel as long as they are at different stages. Pipelining is really just like multi-cycle implementation, except we start the next instruction as soon as we can.
