mask_tile

void ckernel::mask_tile_init()

void ckernel::mask_tile(uint32_t idst_data, uint32_t idst2_mask, DataFormat data_format = DataFormat::Float16_b)

Performs element-wise computation of mask on each element of a tile in data and mask DST register. mask_tile will mask each element with 0, mask_posinf_tile will mask each element with float(inf). The DST register buffer must be in acquired state via acquire_dst call. This call is blocking and is only available on the compute engine.

TODO: fix idst2_mask. currently idst2_mask is not used and (idst_data + 1) is used for mask. because don’t know how to use 2 dst register with sfpu.

Return value: None

Argument	Description	Type	Valid Range	Required
dst_data_index	The index of the tile in DST REG for the data and result	uint32_t	Must be less than the acquired size of DST REG	True
dst_mask_index	The index of the tile in DST REG for the mask	uint32_t	Must be less than the acquired size of DST REG	True
data_format	The format of the data and mask (supports Float16, Float16_b, and Int32)	DataFormat	Must be a valid data format	False
