Detailed Description

Basic function to simulate a scale layer.

This function calls the following OpenCL kernels:

1. kernels::ClScaleKernel

Member Function Documentation

configure()

void configure	(	const CLCompileContext &	compile_context,
		ITensorInfo *	src,
		ITensorInfo *	dst,
		const ScaleKernelInfo &	info
	)

Initialize the function's source, destination, interpolation type and border_mode.

Parameters

[in]	compile_context	The compile context to be used.
[in,out]	src	Source tensor info. Data types supported: U8/QASYMM8/QASYMM8_SIGNED/S16/F16/F32. (Written to only for border_mode != UNDEFINED)
[out]	dst	Destination tensor info. Data types supported: Same as src All but the lowest two dimensions must be the same size as in the input tensor, i.e. scaling is only performed within the XY-plane.
[in]	info	ScaleKernelInfo descriptor to be used to configure

    // Configure Scale kernel
    auto k = std::make_unique<kernels::ClScaleKernel>();
    k->set_target(CLScheduler::get().target());
    k->configure(compile_context, src, dst, info);
    _kernel = std::move(k);

    // Tune kernel
    CLScheduler::get().tune_kernel_static(*_kernel);
}

run()

void run ( ITensorPack &  tensors )

overridevirtual

Run the kernels contained in the function.

Parameters

[in]

tensors

Vector that contains the tensors to operate on.

Reimplemented from ICLOperator.

validate()

Status validate ( const ITensorInfo *  src, const ITensorInfo *  dst, const ScaleKernelInfo &  info  )

static

Static function to check if given info will lead to a valid configuration.
