Minimum

对两个输入数据执行逐元素取最小值操作。对于每一对对应的输入元素，比较其大小，并将较小者存入输出地址。

\[output_i = \min(input0_i, input1_i)\]
输入：

  • input0 - 第一个输入数据地址。

  • input1 - 第二个输入数据地址。

  • param - 参数数组（7个元素），包含以下内容：

    • param[0]: input0_dims 地址（根据维度数量，分配相应空间）

    • param[1]: input1_dims 地址（根据维度数量，分配相应空间）

    • param[2]: output_dims 地址（根据维度数量，分配相应空间）

    • param[3]: strides0 地址（需分配 num_dims * sizeof(int) 空间）

    • param[4]: strides1 地址（需分配 num_dims * sizeof(int) 空间）

    • param[5]: strides_output 地址（需分配 num_dims * sizeof(int) 空间）

    • param[6]: num_dims（维度数量）

  • core_mask(int, 可选) - 核掩码（仅适用于共享存储版本）。

输出：

  • output - 计算结果地址。

支持平台：

FT78NE MT7004

备注

  • FT78NE 支持：int8 (i8), int16 (i16), int32 (i32), fp32 (fp), fp64 (dp)

  • MT7004 支持：int16 (i16), int32 (i32), fp16 (hp), fp32 (fp)

  • 两个输入数据与输出数据的数据类型必须一致。
