METHOD FOR PREGRAM LOADING ON RAM LOCATED IN SUBPROCESSOR SYSTEM

摘要

The method can debug easily the program and prevent the hard copy of the program. This method is performed by the following steps: initializing the system; shifting the program data stored at hard disk (5) to the special address of dual port memory (300) by enabling the reset signal of sub-CPU (100); shifting the program data stored at the dual port memory to RAM (500) by isabling the reset signal; executing the special function by patching the program from the RAM.
