Fuseload architecture for system-on-chip reconfiguration and repurposing

A method, comprising:

• identifying a set of registers coupled with a set of fuses on a die that each have a fuse address, each register of the set of registers having a register address and each fuse of the set of fuses storing a set of trim data available to be copied to the set of registers;
• identifying one or more fuse headers as part of the sets of trim data, each fuse header of the one or more fuse headers corresponding to a fuse group of one or more fuse groups and indicating a mapping between a plurality of fuse addresses for the set of fuses and a plurality of register addresses for the set of registers;
• determining, based at least in part on one or more subfields within each fuse header of the one or more fuse headers, trim data to be copied from each fuse group to a corresponding set of registers using the mapping;
• and
• copying the determined trim data from the set of fuses to the identified set of registers based at least in part on the one or more subfields within each fuse header.

A controller, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the controller to:
• identify a set of fuses on a die;
• identify a set of registers coupled with the set of fuses on the die, the set of fuses for storing trim data to be copied to the set of registers;
• determine, based at least in part on one or more fuse headers within the trim data, a mapping between fuse addresses for the set of fuses and register addresses for the set of registers, wherein each fuse header of the one or more fuse headers comprises information for a plurality of fuse addresses and a plurality of register addresses;
• and
• copy trim data from the set of fuses to the identified set of registers based at least in part on the mapping.

A controller, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the controller to:
• identify a set of registers coupled with a set of fuses on a die that each have a fuse address, each register of the set of registers having a register address, wherein each fuse of the set of fuses is configured to store a set of trim data available to be copied to the set of registers;
• identify one or more fuse headers as part of the sets of trim data, each fuse header of the one or more fuse headers respectively corresponding to a fuse group of one or more fuse groups, wherein each fuse header of the one or more fuse headers is configured to indicate a mapping between a plurality of fuse addresses for the set of fuses and a plurality of register addresses for the set of registers;
• determine, based at least in part on one or more subfields within each fuse header of the one or more fuse headers, trim data to be copied from each fuse group to a corresponding set of registers using the mapping;
• and
• copy the determined trim data from the set of fuses to the identified set of registers based at least in part on the one or more subfields within each fuse header.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by a processor to:

• identify a set of fuses on a die;
• identify a set of registers coupled with the set of fuses on the die, the set of fuses storing trim data to be copied to the set of registers;
• determining, based at least in part on one or more fuse headers within the trim data, a mapping between fuse addresses for the set of fuses and register addresses for the set of registers, wherein each fuse header of the one or more fuse headers comprises information for a plurality of fuse addresses and a plurality of register addresses;
• and
• copy trim data from the set of fuses to the identified set of registers based at least in part on the mapping.
