UnaryRepeatParams

UnaryRepeatParams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；同 一 迭 代 内DataBlock的 地 址 步 长 参 数 说 明 请 参 考dataBlockStride。

结 构 体 具 体 定 义 为：

其 中，blockNumber，repeatStrideMode，strideSizeMode为 保 留 参 数，用 户 无 需 关 心，使 用 默 认 值 即 可。halfBlock表 示CastDeq指 令 的 结 果 写 入 对 应UB的 上 半（halfBlock = true）还 是 下 半（halfBlock = false）部 分。用 户 需 要 自 行 定 义DataBlock Stride参 数，包 含dstBlkStride，srcBlkStride，以 及Repeat Stride参 数，包 含dstRepStride，srcRepStride。
