1.请问k230的理论峰值FLOPS是多少呢,没有找到数据,只找到了C908的满配情况下的数据(在 4 核、2GHz 最大配置下,算力可达 512 Gops (@int8)/ 256 GFlops (@FP16);)。

  1. 另外C908的矢量执行单元似乎不支持FP64,请问k230支持吗?

  1. K230 大核支持RVV 1.0, 运行频率1.6GHz,向量宽度128bit,算力为51.2G @int8, 除了大核外,还有小核运行在800MHz下也能提供算力,此外还有~1T的KPU提供AI 算力;
  2. 矢量单元支持FP64或INT64

感谢回复,另外请教一下,有办法将核心频率固定吗(目前看似乎频率会变?),我用的canmv_ubuntu_sdcard_1.3.img镜像文件。
