Processor customization

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.

Why use processor customization?

Processor customization is typically done to address specific performance, power, or feature requirements in specialized domains such as high-performance computing, embedded systems, wireless & connectivity, artificial intelligence etc. Customized processors can deliver optimized performance, power efficiency, or specific capabilities that are not available in off-the-shelf processors.

What is the difference between processor customization and processor configuration?
Processor configuration involves adjusting pre-defined parameters or settings available on a processor to tweak its behavior or performance in general, while processor customization involves a deep level of the processor’s modification that involves instruction set, microarchitecture and internal resources to create a specialized variant for specific computing tasks.
