transpose_wh_tile

void ckernel::transpose_wh_init(uint32_t icb, uint32_t ocb = 16)

Paired Init function for transpose_wh. For general information on init functions refer to any_init.

Argument	Description	Type	Valid Range	Required
icb	The identifier of the circular buffer (CB) containing input	uint32_t	0 to 31	True

void ckernel::transpose_wh_tile(uint32_t icb, uint32_t itile, uint32_t idst)

Performs a 32x32 transpose operation B[w,h] = A[h,w] on a tile in the CB at a given index 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
in_cb_id	The identifier of the circular buffer (CB) containing A	uint32_t	0 to 31	True
in_tile_index	The index of tile A within the first 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 B	uint32_t	Must be less than the acquired size of DST REG	True
