概述
性能领先的 DSP，用于音频、视觉、AI 应用，支持自动矢量化
HiFi 5s 允许编译器自动进行数据处理矢量化，极大地加快了产品上市速度，省去了耗时的手动优化，让每位嵌入式程序员都可以使用 DSP。它提供双精度 MAC 和 ISA，以加速需要满足大范围、高精度的现代音频算法。HiFi 5s 利用特殊的 ISA 加速轻量级成像和视觉算法。
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 5s DSP，降低开发成本，加速产品上市。ISA 和 MAC 经过扩展，允许现代音频算法利用新增的双精度功能更高效地运行 OOB，并在运行音频的同时运行轻量级视觉用例。
