Abstract: In one embodiment vector conflict detection instructions are disclosed to perform dynamic memory conflict detection within a vectorized iterative scalar operation. The instructions may be performed by a vector processor to generate a partition vector identifying groups of conflict free iterations. The partition vector may be used to generate a write mask for subsequent vector operations.

Abstract translation: 在一个实施例中，公开了矢量冲突检测指令以在矢量化迭代标量运算内执行动态存储器冲突检测。 指令可以由向量处理器执行以产生识别无冲突迭代组的分区向量。 可以使用分区向量来生成用于后续向量操作的写掩码。
