Pipeline
Loops – Improving Performance
CE-653 - Asynchronous Pipeline
Performance
}Bubble-limited loops
}Can improve performance by adding pipeline buffers
}Intuition
}Bubbles need to flow backwards less distance for tokens to flow forward
}Data-limited loops
}Increase multi-threading
}Shorten loop latency
