Overview
Description
The RZ/G3E Ethos package provides guidance on deploying and running Arm® Ethos™-U55 NPU (hereinafter referred to as “the NPU”) software on the Renesas RZ/G3E platform. The RZ/G3E is a heterogeneous SoC that integrates a quad-core Arm Cortex®-A55 processor cluster (hereinafter referred to as “the Cortex-A55 core”), along with an Arm Cortex-M33 core (hereinafter referred to as “the Cortex-M33 core”) for real-time and control tasks. The NPU enables low-power neural network inference via the Cortex-M33 core. This architecture makes it well-suited for edge AI applications, enabling a hybrid computing model where AI workloads are efficiently distributed across cores.
Features
- Ethos-U55 low-power micro NPU designed for embedded and edge devices
- Operates together with Cortex-M class CPUs and offloads AI inference workloads, significantly reducing CPU load.
