Abstract
A programmable processor that includes a pipeline with a number of stages. A stall controller is associated with the pipeline, and detects a hazard condition in at least one of those stages. The stall controller produces a set of signals that can control the stages individually, to stall stages of the pipeline in order to avoid a hazard. In an embodiment, a bubble is formed in the pipeline which allows one instruction to complete prior to allowing the pipeline to continue.
