摘要：A method and system for generating a ROM patch are provided. In one embodiment, a computing device obtains an original assembly code and a modified assembly code which is a modified version of the original assembly code, the original assembly code being used for an executable code which is stored in a ROM of a device. The computing device compares the original assembly code and the modified assembly code to identify difference(s) in the modified assembly code with respect to the original assembly code. The computing device then compiles the difference(s) (sometimes, after adjusting the differences) and generates a ROM patch by converting the compiled difference(s) into a replacement executable code for some of the executable code stored in the ROM of the device. In another embodiment, a method and system for using a ROM patch are disclosed.

主权项：1. A method for generating a read-only memory (ROM) patch, the method comprising: in a computing device: obtaining an original assembly code and a modified assembly code which is a modified version of the original assembly code, the original assembly code being used for an executable code which is stored in a ROM of a device;comparing the original assembly code and the modified assembly code to identify difference(s) in the modified assembly code with respect to the original assembly code;compiling the difference(s); andgenerating a ROM patch by converting the compiled difference(s) into a replacement executable code for some of the executable code stored in the ROM of the device.
