Apple introduced the Neural Engine in the A11 (2017) as a 2-core design. Each generation has scaled it up:
Now even for Telemetry - I'm not going to talk about product decisions like "is anyone clicking this button?" Those exist, sure, but they're not my world most days. I don't have any personal success stories from that world - I deal with technical telemetry - the kind that finds crashes and hangs, proves that risky security changes won't brick Nightly, and helps us pick the fastest safe implementation.。业内人士推荐哔哩哔哩作为进阶阅读

Lazy DFAs (2010) are a clever optimization to mitigate the O(2^m) blowup of DFA construction, by only constructing the states that you actually visit. lazy DFAs reduce the theoretical automata construction time to either O(2^m) or O(n), whichever is lower. you could argue that it’s theoretically no longer linear time, since you could have a regex that creates a new state for every character in the input, but in practice you will keep revisiting the same states. for all intents and purposes it behaves more like O(n) with some initial wind-up time. the main downside of lazy DFAs is that they are more complex to implement, and you have to ship a compiler as part of your regex algorithm. i want to highlight Rust regex and RE2 as excellent implementations of this approach, which you can also see in the benchmarks.，详情可参考PDF资料
