Worked on the XS-MLVP/UnityChipForXiangShan repository to document and stabilize the Shield-XS Bitmap security isolation mechanism, focusing on integration within the memblock module. Emphasized security architecture and system design by detailing workflows, threat models, defense principles, hardware design, and verification strategies. Used Markdown for comprehensive technical writing, ensuring clarity and maintainability. Deprecated and removed outdated frontend bitmap documentation to reduce confusion and maintenance overhead. Demonstrated disciplined documentation practices and cross-team collaboration, supporting future verification and audits. The work strengthened the project’s security posture and architectural clarity, providing a solid foundation for ongoing development and review in computer architecture.
