Cache Coherency 101: Why It Matters in Multi-Core SoCs.
Here's what we cover:
🔹 Why MESI and broadcast snooping break down past ~8 agents — and what replaces them
🔹 How AMBA CHI Rev E.b's DMT, DCT, and DWT cut latency by eliminating redundant hops
🔹 The measured bandwidth hit of heavy coherency traffic (~29 percentage points)
🔹 How chiplet topologies change every snoop cost — and why architecture decisions made today constrain the chiplet path tomorrow
🔹 What ISO 26262 ASIL-B through ASIL-D actually require of your coherent interconnect
🔹 How C-NOC, NC-NOC, Proxy Cache, and Inoculator solve each part of the stack
