VRULL builds the software that makes AI silicon work. ISA extension design, compiler backends (GCC, LLVM), and AI framework integration (PyTorch, TensorFlow, ONNX Runtime) — from architecture through production, for silicon companies building on RISC‑V and ARM.

We don't enable hardware after the fact. We co-develop with it — shaping the ISA extensions, building the toolchains, and shipping the frameworks in parallel with the silicon. When the chip comes back from the fab, the software stack is ready.

RISC‑V International leadership: Vice-Chair of the Technical Steering Committee, Board of Directors, Chair of the Applications & Tools Horizontal Committee. Editor of the Integrated Matrix Extension specification. Ratification Award for Zicond.
