  • Patent number: 11366784
    Abstract: Methods, systems, and devices that support fuseload architectures for system-on-chip (SoC) reconfiguration and repurposing are described. Trim data may be loaded from fuses to registers on a die based on a fuse header. For example, a set of registers coupled with a set of fuses on the die may be identified, where the set of fuses may store trim data to be copied to the registers as part of a fuseload procedure. In such cases, one or more fuse headers may be identified within the trim data, and each fuse header may correspond to a fuse group that includes a subset of fuses. Based on one or more subfields within a fuse header, a mapping between fuse addresses and register addresses may be determined, and the trim data from each fuse group may be copied into a set of registers based on the mapping.
