- TLDR：This work proposes xHC (Expanded Hyper-Connections), the first HC-family method to achieve meaningful expansion beyond $N{=}4$ and introduces xHC-Flash, which reduces the per-sublayer memory traffic from $73.5C$ to $40C, comparable to the $34C$ required by mHC at $N{=}4$, while retaining the gains of full xHC.

- TLDR中文：提出xHC（扩展型超连接），是首个在N=4之外实现有意义扩展的HC系列方法；引入xHC-Flash，将每个子层的内存访问量从73.5C降至40C（与mHC在N=4时的34C相当），同时保留完整xHC带来的性能增益。
