Detailed Description

A framework to accelerate FP32 deconvolution in Synet Framework.

Function Documentation

SimdSynetDeconvolution32fInit()

void * SimdSynetDeconvolution32fInit	(	size_t	batch,
		const SimdConvolutionParameters *	conv,
		SimdSynetCompatibilityType	compatibility
	)

Initilizes FP32 deconvolution algorithm.

Parameters

[in]	batch	- a batch size.
[in]	conv	- a pointer to deconvolution parameters.
[in]	compatibility	- a flags of calculation compatibility.

Returns

a pointer to FP32 deconvolution context. On error it returns NULL. It must be released with using of function SimdRelease. This pointer is used in functions SimdSynetDeconvolution32fExternalBufferSize, SimdSynetDeconvolution32fInternalBufferSize, SimdSynetDeconvolution32fInfo, SimdSynetDeconvolution32fSetParams and SimdSynetDeconvolution32fForward.

SimdSynetDeconvolution32fExternalBufferSize()

size_t SimdSynetDeconvolution32fExternalBufferSize

(

const void *

context

)

Gets size of external temporary buffer required for FP32 deconvolution algorithm.

Parameters

[in]

context

- a pointer to FP32 deconvolution context. It must be created by function SimdSynetDeconvolution32fInit and released by function SimdRelease.

Returns

size of external temporary buffer required for FP32 deconvolution algorithm.

SimdSynetDeconvolution32fInternalBufferSize()

size_t SimdSynetDeconvolution32fInternalBufferSize

(

const void *

context

)

Gets size of internal buffer used inside FP32 deconvolution algorithm.

Parameters

[in]

context

- a pointer to FP32 deconvolution context. It must be created by function SimdSynetDeconvolution32fInit and released by function SimdRelease.

Returns

size of internal buffer used inside FP32 deconvolution algorithm.

SimdSynetDeconvolution32fInfo()

const char * SimdSynetDeconvolution32fInfo

(

const void *

context

)

Gets description of internal implementation of FP32 deconvolution algorithm.

Parameters

[in]

context

- a pointer to FP32 deconvolution context. It must be created by function SimdSynetDeconvolution32fInit and released by function SimdRelease.

Returns

string with description of internal implementation of FP32 deconvolution algorithm.

SimdSynetDeconvolution32fSetParams()

void SimdSynetDeconvolution32fSetParams	(	void *	context,
		const float *	weight,
		SimdBool *	internal,
		const float *	bias,
		const float *	params
	)

Sets weights, beases and parameters of activation function required for FP32 deconvolution algorithm.

Parameters

[in,out]	context	- a pointer to FP32 deconvolution context. It must be created by function SimdSynetDeconvolution32fInit and released by function SimdRelease.
[in]	weight	- a pointer to deconvolution weights.
[out]	internal	- a flag signalized that weight is stored in the internal buffer. Can be NULL.
[in]	bias	- a pointer to bias. Can be NULL.
[in]	params	- a pointer to parameters of activation functions (see SimdConvolutionActivationType). Can be NULL.

SimdSynetDeconvolution32fForward()

void SimdSynetDeconvolution32fForward	(	void *	context,
		const float *	src,
		float *	buf,
		float *	dst
	)

Performs forward propagation of FP32 deconvolution algorithm.

Parameters

[in]	context	- a pointer to FP32 deconvolution context. It must be created by function SimdSynetDeconvolution32fInit and released by function SimdRelease.
[in]	src	- a pointer to input tensor.
[out]	buf	- a pointer to external temporary buffer. The size of the external temporary buffer is determined by function SimdSynetDeconvolution32fExternalBufferSize. Can be NULL (it causes usage of internal buffer).
[out]	dst	- a pointer to output tensor.
