Developed cross-platform build toolchain support for the AK3918 and SS928 architectures within the Tencent/ncnn repository, focusing on expanding multi-architecture compatibility. Leveraged CMake configuration and Linux development skills to implement new cross-compilation toolchain files, streamlining the build process and reducing manual setup for these platforms. The work enhanced the reliability and scalability of the build system, aligning with ongoing efforts to support additional architectures. By introducing robust cross-compilation support, the developer enabled more efficient integration of new hardware targets. The project was completed without major bug fixes, emphasizing depth in build system engineering and proficiency with CMake and cross-compilation.
