BinaryRepeatParams

BinaryRepeatParams is a data structure that controls the operand address strides. It contains such parameters as those that specify the address stride of the operand for the same data block between adjacent iterations and address stride of the operand between different data blocks in a single iteration.

For details about the address stride of the operand between adjacent iterations, see repeatStride. For details about the address stride of the operand between different data blocks in a single iteration, see dataBlockStride.

The specific definition of the structure is as follows:

blockNumber, repeatStrideMode, and strideSizeMode are reserved parameters. You can use the default values. You need to define the dataBlockStride parameters (including dstBlkStride, src0BlkStride, and src1BlkStride) and repeatStride parameters (including dstRepStride, src0RepStride, and src1RepStride).
