| * @param[in] compile_context The compile context to be used. |
| * @param[in] src The src tensor info to convolve. 3 lower dimensions represent a single src [width, height, IFM], |
| * while every optional dimension from 4 and above represent a batch of inputs. Data types supported: QASYMM8_SIGNED/QASYMM8/F16/F32. |
| * @param[in] weights Weights tensor info. Weights are 4D tensor with dimensions [kernel_x, kernel_y, IFM, OFM]. |
| * The 3rd dimension must be the same as the src's volume 3rd dimension. |
| * Data type supported:Same as @p src. |
| * @param[in] biases Biases tensor info. Biases are 1D tensor with dimension [OFM]. |
| * Data type supported: Should match @p src data type, except for src of QASYMM8 and QASYMM8_SIGNED type where biases should be of S32 type |
| * @param[out] dst Output tensor info. |
| * The 3rd dimensions must be equal to the 4th dimension of the @p kernels tensor. Data types supported: Same as @p src. |
| * @param[in] conv_info Contains padding and stride information described in @ref PadStrideInfo. |
| * @param[in] act_info Contains activaton information described in @ref ActivationLayerInfo. |
