Quick Guide to ARM Assembly Development: Tips, Bugs, and Performance Optimization

This quick‑start guide walks readers through ARM assembly development by teaching simple template functions, exposing typical parameter‑passing and register bugs with debugging tricks, and demonstrating a depthwise convolution written in assembly that delivers roughly 4.7× faster inference on a Huawei Mate40 Pro compared to its C++ counterpart, while also covering ARM32/ARM64 register conventions, vector instructions, and floating‑point handling.

Elevated Road Network (ERNet): A Lightweight Industrial‑Grade Neural Network for Elevated Road and Yaw Detection in Mobile Navigation

ERNet is a lightweight industrial‑grade neural network that detects elevated roads and vehicle yaw in mobile navigation by leveraging four high‑semantic features—satellite plane projection, group ID, elevated‑road distance, and sequential speed—trained on roughly one billion auto‑labeled samples and achieving about 99 % precision/recall and over 99 % yaw accuracy, surpassing existing map‑matching and machine‑learning baselines.
