描述

深层神经网络中使用的人工智能 (AI) 技术已为 IT 领域提供了新的价值。 虽然很多人希望用 AI 技术实现嵌入式应用,但 AI 处理需要大量计算,由于性能不足或功耗需求较大,导致难以使用搭载 CPU 或 GPU 的传统解决方案来适应嵌入式设备。 此外,AI 技术在不断演进,而新的算法也在不断发展。

在 AI 快速发展的过程中,瑞萨开发出了高性能、低能耗且能够随着演进做出响应的 AI 加速器 (DRP-AI) 和软件(DRP-AI 转换器)。 DRP-AI 和 DRP-AI 转换器相结合可实现高功效的 AI 推理,而这是当前的 AI 技术无法支持的。

随着 DRP-AI 转换器的不断更新,AI 模型还可得到扩展。

DRP-AI Features

DRP-AI 的功能

DRP-AI 由 AI-MAC(乘积累加处理器)和 DRP(可重构处理器)组成。 AI 处理可通过在卷积层和全连接层为运算分配 AI-MAC 来高速执行,而且 DRP 也适用于预处理和池化层等其他复杂的处理。

有关 DRP-AI 的更多详细的技术信息,请参考以下白皮书。
白皮书:Embedded AI-Accelerator DRP-AI (PDF | English, 日本語)

While most AI accelerators specialize only in AI inference and rely on the CPU for pre- and post-processing, DRP-AI integrates pre- and post-processing and AI inference into a single DRP-AI hardware to achieve superior AI processing performance.

工具:DRP-AI TVM*1

DRP-AI TVM is a tool that is available to convert trained AI models into a format that can run on DRP-AI. DRP-AI TVM applies the DRP-AI accelerator to the proven ML compiler framework Apache TVM*2. This enables support for multiple AI frameworks (ONNX, PyTorch, TensorFlow, etc.). In addition, it enables operation in conjunction with the CPU, allowing more AI models to be run.

The AI model formats and products (MPUs) supported by DRP-AI TVM are as follows.

  • Input file format (trained AI model): ONNX, PyTorch, TensorFlow
  • Products: RZ/V2M, RZ/V2MA, RZ/V2L, RZ/V2H, RZ/V2N

The table below shows the download site for DRP-AI TVM, a brief description of the tool and information on deliverables.
