Summary
🤩
Rockstar🎓
Top SchoolNicolas Brunie is a Senior Principal Hardware Engineer based in California with a PhD in Computer Science and over a decade of specialized experience in floating-point units, vector execution, and RISC-V microarchitecture. He has progressed through technical and leadership roles at SiFive and Kalray, driving high-performance FPU and out-of-order vector designs, Chisel-based RTL flow automation, and PPA-driven micro-architecture iteration. His background uniquely combines compiler backend work, cryptographic co-processor design, and low-level software optimization—skills honed while developing LLVM backends, cryptography accelerators, and optimized math libraries during his PhD and industry roles. Known for bridging hardware and software, he has led teams building CNN accelerators and embedded ML stacks while still contributing deep RTL and algorithmic expertise. Colleagues rely on him for pragmatic architecture choices that squeeze frequency and efficiency out of modern cores without sacrificing standards compliance.
