讲师简介 / Speaker Bio Wei-Han Lien is a Chief Architect and Senior Fellow in Machine Learning hardware architecture. He is currently leading an architecture team in defining a high-performance RISC-V CPU, fabric, system caching, and high-performance memory subsystem for the Tenstorrent heterogeneous high-performance computation platform for AI and HPC computing. He is also leading the definition of Tenstorrent's chiplet architecture for constructing scalable, configurable, and composable SiP with cohesive power management, security, and system management architectural definitions for compatibility. Before joining Tenstorrent, Wei-Han joined Apple through the PA Semi acquisition. He led Apple design team on the microarchitectural definitions of two of the most transformative Apple iPhone/iPad application processors from scratch, the A6 and A7 CPU projects. The Apple A7 CPU core is a solid CPU microarchitecture substrate for future generations of A-series (A7-A14) iPhone/iPad mobile processors and M-series (M1) MacBookPro processors. Before Apple, he was a distinguished architect leading P.A.Semi's PWRficient PA6T dual O-o-O triple-issue superscalar PowerPC CPU cores. At Raza Microelectronics, he led the microarchitectures of the single-chip 40Gb scalable shared-memory switching chip and distributed-shared-memory cache coherent Ethernet switch. He joined Nexgen and AMD after graduating from the University of Michigan; he was part of a team designing the Nx586 (AMD K6), the most competitive microprocessor product to the Intel Pentium processor from 1997-1999 in the market. |
