U74 High performance Linux-capable RISC V processor

Overview

The SiFive U74 Standard Core is a single-core instantiation of the world's highest performance RISC-V application processor, capable of supporting full-featured operating systems such as Linux.
The U74 is ideal for applications requiring high-throughput, single-thread performance -- but have power constraints (e.g., AR, VR, sensor hubs, IVI systems, IP cameras, digital cameras, gaming devices, etc.)
