Parameters

[in]	input_row	pointer to row operand
[in]	input_col	pointer to col operand
[in]	output_ch	number of rows of input_row
[in]	col_batches	number of column batches. Range: 1 to 4
[in]	output_shift	pointer to per output channel requantization shift parameter.
[in]	output_mult	pointer to per output channel requantization multiplier parameter.
[in]	out_offset	output tensor offset.
[in]	col_offset	input tensor(col) offset.
[in]	row_offset	kernel offset(row). Not used.
[in]	out_activation_min	minimum value to clamp the output to. Range : int8
[in]	out_activation_max	maximum value to clamp the output to. Range : int8

Returns

The function returns one of the two

1. The incremented output pointer for a successful operation or
2. NULL if implementation is not available.
