Latest Patents
Warren R. Stearns holds a patent for a "Firmware ROM patch method." This system allows firmware in ROM to be upgraded without the need to re-spin silicon. A one-bit flag is assigned for each patchable function, representing a firmware upgrade. The first statement of each function checks its associated flag to determine if patch-code should be executed instead of the current function in ROM. If the flag is not set, the code continues executing normally. If the flag is set, a function identifier is placed into a global memory location, and an assembly language 'jump' instruction is executed. This redirects program control to a specified location in volatile Scratch Read Only Memory (SROM) where the corresponding patched code is stored. If multiple functions are patched, the global identifier helps determine which patched function to execute. The use of an assembly language 'jump' instruction allows the patched function to return normally to its calling function after execution.
