configure()

void configure	(	const ITensorInfo *	src,
		ITensorInfo *	dst
	)

Configure the kernel.

Parameters

[in]	src	Source tensor info. Data types supported: QASYMM8/QASYMM8_SIGNED/QSYMM8_PER_CHANNEL/QSYMM8/QSYMM16.
[out]	dst	Destination tensor info with the same dimensions of input. Data type supported: F16/F32.
