概述
多功能、超低功耗 DSP，用于音频、语音、视觉和 AI 应用
HiFi 1s 有三大优势：首先，它支持编译器的自动矢量化功能，无需进行手动优化，因此每个嵌入式程序员都可以使用。其次，它增强了始终开启型 AI 应用的能力，允许在超低功耗 DSP 上运行性能更高的机器学习算法。最后，它增加了成像 ISA，用于支持轻量级始终开启型视觉处理。
利用自动矢量化功能，程序员不必再耗费时间和精力进行复杂的手动优化，让大量的非 DSP 程序员也可以使用 HiFi 1s DSP，降低开发成本，加速产品上市。利用扩展后的 AI 和成像 ISA，轻量级视觉和机器学习应用能够以超低功耗运行。双精度 ISA 有助于高效运行现代化音频应用。
