AMBA CHI (Coherent Hub Interface) is ARM's high-performance cache-coherent interconnect protocol used in modern SoCs.
It allows multiple CPUs, GPUs, and AI accelerators to share memory efficiently without data inconsistency.
✅ 4 Key Channels:
• REQ — Send request
• RSP — Get acknowledgment
• SNP — Maintain cache coherency
• DAT — Transfer actual data
💡 Why CHI?
Older protocols like AXI/ACE break at 8+ cores. CHI scales to 128+ cores using a distributed mesh architecture — no single bottleneck.
📌 Used in: ARM Neoverse, Apple M-series, AI chips, Automotive SoCs.
