Reusing developed object program

Existing developed object program can be converted to file formats that can be loaded to FPGA memories.
These memories and processor IP can be implemented in FPGA, which can be debugged by using emulators for the processor. Through disassemble of object, you can understand the program. Also, you can check the operation of the program.
In a way like this, you can use existing developed object program with the processor IP.
