void ckernel::sub_tiles_init(uint32_t icb0 = 0, uint32_t icb1 = 1, bool acc_to_dest = false)

Short init function

Argument	Description	Type	Valid Range	Required
icb0	The identifier of the circular buffer (CB) containing A	uint32_t	0 to 31	True
icb1	The identifier of the circular buffer (CB) containing B	uint32_t	0 to 31	True
acc_to_dest	If true, operation = A - B + dst_tile_idx of sub_tiles	bool	0,1	False

void ckernel::sub_tiles(uint32_t icb0, uint32_t icb1, uint32_t itile0, uint32_t itile1, uint32_t idst)

Performs element-wise subtraction C=A-B of tiles in two CBs at given indices and writes the result to the DST register at index dst_tile_index. 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.

Return value: None

Argument	Description	Type	Valid Range	Required
in0_cb_id	The identifier of the circular buffer (CB) containing A	uint32_t	0 to 31	True
in1_cb_id	The identifier of the circular buffer (CB) containing B	uint32_t	0 to 31	True
in0_tile_index	The index of tile A within the first CB	uint32_t	Must be less than the size of the CB	True
in1_tile_index	The index of tile B within the second CB	uint32_t	Must be less than the size of the CB	True
dst_tile_index	The index of the tile in DST REG for the result C	uint32_t	Must be less than the acquired size of DST REG	True
