System and method for translating high-level programming language code into hardware description language code

摘要

The present invention is directed to a method and system for translating a high-level language (HLL) code such as C, C++, Fortran, Java or the like into a HDL code such as Verilog or VHDL which requires no modification in the original HLL source code, while supporting a cross call between software and hardware, and even recursive calls in hardware. The system includes: a HLL-to-HLL source translator which reads user programming directive from a translation-targeted high-level language code marked with the user directive, and separates the translation-targeted high-level language code into a hardware code part and a software code part; a main compiler which compiles the software code part; a HLL-to-HDL translator which includes the front-end and middle-end of the main compiler and a HDL backend; a main core which executes the compiled software code part; and a dedicated hardware which executes the HDL code.
