# BinaryRepeatParams

BinaryRepeatParams为用于控制操作数地址步长的数据结构。结构体内包含操作数相邻迭代间相同DataBlock的地址步长，操作数同一迭代内不同DataBlock的地址步长等参数。

相邻迭代间的地址步长参数说明请参考repeatStride(https://www.hiascend.comdocument/detail/zh/canncommercial/900/programug/Ascendcopdevg/atlas_ascendc_10_0022.html#ZH-CN_TOPIC_0000002562282205__zh-cn_topic_0000002267504656_zh-cn_topic_0000001764162593_section139459347420)；同一迭代内DataBlock的地址步长参数说明请参考dataBlockStride(https://www.hiascend.comdocument/detail/zh/canncommercial/900/programug/Ascendcopdevg/atlas_ascendc_10_0022.html#ZH-CN_TOPIC_0000002562282205__zh-cn_topic_0000002267504656_zh-cn_topic_0000001764162593_section2815124173416)。

结构体具体定义为：

```
const int32_t DEFAULT_BLK_NUM = 8;
const int32_t DEFAULT_BLK_STRIDE = 1;
const uint8_t DEFAULT_REPEAT_STRIDE = 8;

struct BinaryRepeatParams {
    __aicore__ BinaryRepeatParams() {}
    __aicore__ BinaryRepeatParams(const uint8_t dstBlkStrideIn, const uint8_t src0BlkStrideIn,
        const uint8_t src1BlkStrideIn, const uint8_t dstRepStrideIn, const uint8_t src0RepStrideIn,
        const uint8_t src1RepStrideIn)
        : dstBlkStride(dstBlkStrideIn),
          src0BlkStride(src0BlkStrideIn),
          src1BlkStride(src1BlkStrideIn),
          dstRepStride(dstRepStrideIn),
          src0RepStride(src0RepStrideIn),
          src1RepStride(src1RepStrideIn)
    {}
    uint32_t blockNumber = DEFAULT_BLK_NUM;
    uint8_t dstBlkStride = DEFAULT_BLK_STRIDE;
    uint8_t src0BlkStride = DEFAULT_BLK_STRIDE;
    uint8_t src1BlkStride = DEFAULT_BLK_STRIDE;
    uint8_t dstRepStride = DEFAULT_REPEAT_STRIDE;
    uint8_t src0RepStride = DEFAULT_REPEAT_STRIDE;
    uint8_t src1RepStride = DEFAULT_REPEAT_STRIDE;
    bool repeatStrideMode = false;
    bool strideSizeMode = false;
};
```

其中，blockNumber，repeatStrideMode和strideSizeMode为保留参数，用户无需关心，使用默认值即可。用户需要自行定义DataBlock Stride参数，包含dstBlkStride，src0BlkStride和src1BlkStride，以及Repeat Stride参数，包含dstRepStride，src0RepStride和src1RepStride。
