An Emulation and Context Reconstruction Tool for Embedded High-Precision Positioning System

This article presents an emulation and program context reconstruction tool for a real-time high-precision positioning embedded system. This tool records the context of the embedded software in the operation without affecting runtime behavior. The execution procedure is re-created on a host machine off-line through reconstruction. This approach successfully accelerates the debugging and fault diagnosis process of transient or intermittent errors during the run time.
