My Technology Focus
- Compiler, assembler, linker, loader, debugger, and library.
- GNU tools development. I have port GCC, Binutils, GDB, Newlib, to a RISC
chip. The binutils port have entered GNU

Industry: Software Location: BeiJing Job Type: Full-time Job Category: Senior Software Engineer Career Level: Senior Position (Non-managerial) Responsibilities and Achievements: 2006/11 - 2008/4 Sr. Engineer&Team Leader Sunplus Compilers&Tools Group
- Wrote GCC machine description file.
Design the second generation ISA for chip SCORE with the purpose of
improving performance, especially focusing at reducing code size.
The ISA is hybrid that contain 16 bit and 32 bit instructions. Our purpose is to add more 16 bit instructions to reduce code size based on benchmark
analysis and tuning.
- Wrote GCC machine description file.
This work is based on GCC-4.0.
After running EEMBC and a group of open source benchmark, the code size
reduced approximate 25 percent compared to the first generation ISA.
- Implement GDB for chip SCORE.
This work is based on GDB-6.5. Wrote the interfaces between GDB and
simulator.
GDB server and stub are not fulfilled, maybe, they are future’s work.
2005/02 - 2006/10 Team Leader Sunplus Compilers&Tools Group
- Porting GNU Binutils-2.16.1 to chip SCORE.
The assembler support relax optimization which change 16 bit instruction to
32 bit instruction or change 32 bit instruction to 16 bit instruction in order to
obtain the best performance and the smallest code size.
The linker support PIC and dynamic linking.
These codes have been merged into GNU official release and I am the port
maintainer of SCORE Binutils.
- Porting Newlib to SCORE.
Wrote the low level system functions and I/O functions.
Wrote a group of black-box and white-box testsuite.
- Responsible for planning and designing loader for SCORE, Programming
done by another team member.
2003/05 - 2005/01 Engineer Sunplus Compilers&Tools Group
- Wrote assembler, linker and disassembler for a self-designed DSP chip.
This assembler is implemented with Lex and Yacc. Afterwards, improved
these tools in many technology points to gain better performance and added STABS debug information to support assembly level debugging.
- Wrote a front-end with Lex and Yacc for a type of assembly language source navigator.
