Title: Cheng-Han Wu and Firmware Boot Tracing.
Introduction
Cheng-Han Wu is an inventor based in Taoyuan, Taiwan, whose work includes firmware debugging and boot-process diagnostics. He is associated with Quanta Computer Incorporated.
Latest Patents
Wu is credited with 1 patent, titled “Firmware Boot Tracing.” The invention enables firmware, such as a BIOS, to generate and output trace data during execution while limiting performance impact and avoiding disclosure of sensitive firmware information. It uses one-way hash digests of firmware modules, which can be checked against a pre-established mapping table to identify modules that completed or failed during execution, including during startup. The approach is designed to support debugging while making module code harder to expose through unauthorized reverse engineering.
Career Highlights
Wu’s patent work addresses a practical challenge in firmware development: diagnosing startup and execution problems without substantially slowing firmware or revealing protected code. His association with Quanta Computer Incorporated places this work in the context of computer hardware and firmware engineering.
Collaborations
Jyun-Jie Huang and Cheng-Han Chen are identified as Wu’s coworkers.
Conclusion
Cheng-Han Wu’s firmware boot tracing invention combines hash-based diagnostics with attention to performance and code confidentiality, offering a way to investigate firmware execution issues more securely.
