| Abstract | This paper describes the High-performance C Compiler (HCC) and its specific implementation for industrial application-specific embedded System on Chips (SoCs). HCC compiler is a language C compiler based on the retargetable GCC compiler. Because of the specialized architectures and features of specific embedded SoCs, machine-dependent compiler implementation is an important and challenging work in embedded system. To quickly implement a compiler for specific embedded SoCs, compiler extension methods are proposed in HCC compiler. We extend the identifier and attribute with Abstract Syntax Tree (AST) for language-specific programming syntax of the compiler front-end, which is the syntax of the extended standard ANSI C. And then, the machine-dependent classification of assembly generation for the specific embedded SoCs is designed and implemented. After finishing the ABI (Application Binary Interface) and MD (Machine Description) of the compiler back-end, the HCC compiler is completed by retargeting GCC compiler for the application-specific embedded SoCs. These implementation methods could be referenced for other embedded chips. According to the crossing contrasts and tests with multiple compilers of the same type, conclusion can be drawn that the proposed HCC compiler has a stable performance with excellent improvement of the generated assembly codes.
