$2 微控制器上的 SIMD 加速计算机视觉
SIMD-accelerated computer vision on a $2 microcontroller
AI 导读
Hacker News 首页文章讨论在 $2 微控制器上用 SIMD 加速计算机视觉，处理速度从 5.1MP/s 提升到 112MP/s。评论区指出原文"提升 220%"的说法有误，实际是提升 120%、即 2.2 倍加速，百分比增长应从 0% 起算而非 100%。
正文
 | peesem 0 minutes ago | [–] nit: 5.1MP/s to 11.2MP/s is not an increase of 220%, it's an increase of 120%. it's 2.2x faster, but percentage increase starts at 0%, not 100%. 100% faster is double, 200% faster is triple. |
