Kernel used to quantize down the int32 accumulator values of GEMMLowp to QSYMM16.
This kernel takes a final int32 accumulator value (the output of CpuGemmLowpMatrixMultiplyKernel), and processes it to obtain the final QSYMM16 value. The following computations will be performed by the kernel:

Initialise the kernel's input and output.
[in] | src | Input tensor info. Data type supported: S32 |
[in] | bias | Biases tensor info. Only shared biases supported and it can be a nullptr if the biases addition is not required. Biases are 1D tensor with dimensions [OFM]. Data type supported: Same as input . |
[out] | dst | Output tensor info. Data type supported: Data type supported: QSYMM16 |
[in] | result_fixedpoint_multiplier | Fixed point value to be multiplied to each element of the input matrix when once the result_offset has been add |
[in] | result_shift | Integer value used to round to nearest division by a power-of-two the result after the fixed point multiplication |
[in] | min | (Optional) Min value used to saturate down the output result before converting back to QSYMM16. Defaults to 0. |
[in] | max | (Optional) Max value used to saturate up the output result before converting back to QSYMM16. Along with min , this value can be used to implement "rectified linear unit" activation functions. Defaults to 0. |
