TPUsid
TPUsid is a standardized identification scheme introduced in 2024 for Tensor Processing Unit (TPU) devices manufactured by leading semiconductor firms. Its primary purpose is to provide a globally unique identifier that encapsulates key metadata about each TPU, including generation, variant, firmware revision, and manufacturing batch. The scheme is defined by the International Semiconductor Identification Authority (ISIA) and is adopted by major GPU and TPU vendors to streamline device traceability, supply chain management, and lifecycle support.
The TPUsid format is a 192-bit string encoded in hexadecimal. The first 32 bits represent the device
Adoption of TPUsid has been driven by increasing concerns over supply‑chain security and regulatory compliance in
Overall, TPUsid represents a collaborative effort to bring uniformity and enhanced security to the rapidly growing
