发明名称 MECHANISM FOR IMPLEMENTING A MICROCODE PATCH DURING FABRICATION
摘要 A patch apparatus in a microprocessor is provided. The patch apparatus includes a plurality of fuse banks and an array controller. The plurality of fuse banks is configured to store associated patch records that are employed to patch microcode or circuits in the microprocessor. The array controller is coupled to the plurality of fuse banks, and is configured to read the associated patch records, and is configured to provide the associated patch records to a patch loader, where the patch loader provides patches corresponding to the associated patch records, as prescribed, to designated target patch mechanisms in the microprocessor. The patch loader provides the patches to the designated target patch mechanisms following transition of a microprocessor reset signal and prior to execution of instructions stored in a BIOS ROM.
