okk_bdc_32bit_cpy

void okk_bdc_32bit_cpy(local_addr_t dst_addr, local_addr_t src_addr, const dim4 *shape, const dim4 *dst_stride, const dim4 *src_stride)

Copy the elements of the source tensor to the destination tensor for 32-bit data type.

\[dst(n, c, h, w) = src(n, c, h, w)\]

Parameters

• dst_addr – Address of the destination tensor.

• src_addr – Address of the source tensor.

• shape – Pointer to the shape of the destination tensor.

• dst_stride – Pointer to the stride of the destination tensor.

• src_stride – Pointer to the stride of the source tensor.

Remarks

• The data type of the destination and source tensor is 32-bit.

• The destination and source tensors start at the same NPU.

• dst_addr and src_addr are divisible by 4 and preferred by 128.

• shape->n, shape->h and shape->w are in [1, 65535], shape->c is in [1, 4095].

• If dst_stride or src_stride is NULL, the relative tensor is in the 128-Byte Aligned Layout.

okk_bdc_32bit_set_C

void okk_bdc_32bit_set_C(local_addr_t dst_addr, x32 C, const dim4 *shape, const dim4 *dst_stride)

Set all the elements of the destination tensor to be a constant value for 32-bit data type.

\[dst(n, c, h, w) = C\]

Parameters

• dst_addr – Address of the destination tensor.

• shape – Pointer to the shape of the destination tensor.

• dst_stride – Pointer to the stride of the destination tensor.

Remarks

• The data type of the destination tensor is 32-bit.

• dst_addr is divisible by 4 and preferred by 128.

• shape->n, shape->h and shape->w are in [1, 65535], shape->c is in [1, 4095].

• If dst_stride is NULL, the destination tensor is in the 128-Byte Aligned Layout.
