Title: Rom patching
Inventor: LARRI GUY
IPC: G06F9/445
Filed: 1994-08-19
Abstract: A data processing system having a central processor unit core 8 operating under control of program instructions stored within a read only memory 10 may be subject to mistakes within the program instructions. In order to deal with this, patch program instructions are stored within a patch memory 6. A breakpoint detector 14 monitors the address bus to the read only memory 10 and detects when an access is made to an address known to contain a mistake. Upon such an access, an interrupt handler 16 serves to divert processing to the patch stored within the patch memory 6 by writing a new value into a program counter register 12 coupled to the central processor unit core 8. At the end of the patch, control is returned to the program instructions of the read only memory 10. <IMAGE>
