  • System and method for modifying a sequence of instructions in a read-only memory of a computing device
    Patent number: 9547489
    Abstract: A system and method for patching a boot sequence in a read-only memory. Patch instances are provided in an addressable memory. The patch instances are initially empty. The read-only memory includes a process that dynamically vectors to identified locations in a set of addressable memory locations in the addressable memory. Thereafter, the process returns to the next subsequent instruction following the patch instance. As corrections are required, the one or more patch instances are populated with one or more respective patches. The boot sequence is modified by inserting one or more patch indicators located where patches might need to be applied after a system-on-chip (SoC) is embodied in firmware. The patches, when defined, are populated with at least an encoded instruction type and an address. Accordingly, a patch is enabled in no more than three words.
