Debugging of Target Assembly Library Codes Using Host Debugging Tool

Since development of digital system becomes more sensitive to time-to-market than ever, it is necessary to reduce development time. This paper describes a debugging method for library function written in assembly language without a target debugging tool which is developed in the later stage of SoC development. The proposed method can reduce the time required to port and debug codes written in assembly language such as library functions and OS kernels. In the proposed method, an assembly library function is translated into a C function with debugging information which can be used in a host debugging tool.
