◆ rppt_tensor_max_gpu()

RppStatus rppt_tensor_max_gpu	(	RppPtr_t	srcPtr,

		rppHandle_t	rppHandle
	)

Tensor max operation on HIP backend for a NCHW/NHWC layout tensor.

The tensor max is a reduction operation that finds the channel-wise (R max / G max / B max) and overall max for each image in a batch of RGB(3 channel) / greyscale(1 channel) images with an NHWC/NCHW tensor layout.

srcPtr depth ranges - Rpp8u (0 to 255), Rpp16f (0 to 1), Rpp32f (0 to 1), Rpp8s (-128 to 127).

dstPtr depth ranges - Will be same depth as srcPtr.
