What is processor customization?

Processor customization refers to the modification or adaptation of a processor’s instruction set or/and microarchitecture to suit specific needs or requirements.

This level of customization involves making changes at a lower level to create a processor variant tailored to a particular application or use case.

Customization can involve modifying the processor’s internal structure, adding or removing certain functional units, optimizing pipelines, or even introducing new custom instructions or extensions.
