Microarchitecture: What Lies Beneath
Matt Godbolt
You know that modern CPUs use out-of-order execution and branch prediction. This talk goes deeper: into the actual implementation details of Intel microarchitecture, specifically Skylake. We'll explore how the execution engine really works - register files, schedulers, and memory disambiguation.
Following a real code snippet along the pipeline, we'll cover the basics, but then dive into the real-world complexity that textbooks skip. Particularly relevant for latency-sensitive systems, but really for anyone who wants to understand what's actually happening beneath their code.
