What Semifive works on
Custom Silicon
Custom silicon means a company designs its own chips for its own products or data centers instead of buying standard parts. The chip is made by a foundry such as TSMC, but the design belongs to the customer.
AI Accelerators
An AI accelerator is a chip, or a part of a chip, designed to run machine learning faster or with less energy than a general-purpose processor. The category includes GPUs, TPUs, neural processing units (NPUs) and chips from many startups.
