Self-Timed Pipeline with Variable Stage Number*

The paper analyzes the problem of improving the self-timed pipeline’s performance. The paper considers possible options for reducing the pipeline latency by decreasing the number of actively operating stages when certain conditions occur, determined by the processed data value or an external signal. One stage bypassing becomes appropriate if it occurs in at least 64% of data processing operations, while two stage bypassing decreases the average pipeline latency if it occurs in 50% of operations.
