Gridworkz Documentation

Gridworkz is an open-source heterogeneous compute platform: a quad-core RISC-V64 host, dual edge NPUs, and the G100 GPU with a co-packaged photonic tensor accelerator chiplet. All RTL, compilers and runtime code are Apache 2.0.

Where to start

• Run something now: GCA SDK quickstart
• Program the photonic chiplet: Photonic compute API
• Read the hardware: RISC-V64 host · NPU · G100 · Pinout
