AMBA CHI: The Industry Standard

ACE uses wires to connect cores. If you have 64 cores, you need millions of wires. It's too messy!

CHI turns the chip into a Network (like the Internet). Cores send "Packets" to each other through a "Hub". This is much cleaner and faster for big chips.

• Nodes: The participants (RN, HN, SN).
• Layers: How CHI separates logic from wires.
• Packets & Flits: How data is "packaged" for transport.
• Flow Control: How credits prevent traffic jams.
