Initialise the kernel's input, dst and border mode.
Valid configurations (Src1,Src2) -> Dst :
Support: Broadcast? Scale=1/255?
scale
equal to 1/255 only round to nearest even (implemented as round half up) is supported. For all other scale values only round to zero (implemented as round towards minus infinity) is supported.[in] | src1 | First input tensor. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/S32/QSYMM16/F16/F32 |
[in] | src2 | Second input tensor. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/S32/QSYMM16/F16/F32 |
[out] | dst | Dst tensor. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/S32/QSYMM16/F16/F32 |
[in] | scale | Scale to apply after multiplication. Scale must be positive and its value must be either 1/255 or 1/2^n where n is between 0 and 15. If both src1 , src2 and dst are of datatype S32, scale cannot be 1/255 |
[in] | overflow_policy | Overflow policy. ConvertPolicy cannot be WRAP if any of the inputs is of quantized datatype |
[in] | rounding_policy | Rounding policy. |
