Detailed Description

A framework to accelerate FP32 merged convolution in Synet Framework.

Function Documentation

SimdSynetMergedConvolution32fInit()

void * SimdSynetMergedConvolution32fInit	(	size_t	batch,
		const SimdConvolutionParameters *	convs,
		size_t	count,
		SimdBool	add,
		SimdSynetCompatibilityType	compatibility
	)

Initilizes FP32 merged convolution algorithm.

Parameters

[in]	batch	- a batch size.
[in]	convs	- an array with convolutions parameters.
[in]	count	- a number of merged convolutions.
[in]	add	- a flag that signilizes if we need to add output to source value.
[in]	compatibility	- a flags of calculation compatibility.

Returns

a pointer to FP32 merged convolution context. On error it returns NULL. It must be released with using of function SimdRelease. This pointer is used in functions SimdSynetMergedConvolution32fExternalBufferSize, SimdSynetMergedConvolution32fInternalBufferSize, SimdSynetMergedConvolution32fInfo, SimdSynetMergedConvolution32fSetParams and SimdSynetMergedConvolution32fForward.

SimdSynetMergedConvolution32fExternalBufferSize()

size_t SimdSynetMergedConvolution32fExternalBufferSize

(

const void *

context

)

Gets size of external temporary buffer required for FP32 merged convolution algorithm.

Parameters

[in]

context

- a pointer to FP32 merged convolution context. It must be created by function SimdSynetMergedConvolution32fInit and released by function SimdRelease.

Returns

size of external temporary buffer required for FP32 merged convolution algorithm.

SimdSynetMergedConvolution32fInternalBufferSize()

size_t SimdSynetMergedConvolution32fInternalBufferSize

(

const void *

context

)

Gets size of internal buffer used inside FP32 merged convolution algorithm.

Parameters

[in]

context

- a pointer to FP32 merged convolution context. It must be created by function SimdSynetMergedConvolution32fInit and released by function SimdRelease.

Returns

size of internal buffer used inside FP32 merged convolution algorithm.

SimdSynetMergedConvolution32fInfo()

const char * SimdSynetMergedConvolution32fInfo

(

const void *

context

)

Gets description of internal implementation of FP32 merged convolution algorithm.

Parameters

[in]

context

- a pointer to FP32 merged convolution context. It must be created by function SimdSynetMergedConvolution32fInit and released by function SimdRelease.

Returns

string with description of internal implementation of FP32 merged convolution algorithm.

SimdSynetMergedConvolution32fSetParams()

void SimdSynetMergedConvolution32fSetParams	(	void *	context,
		const float *const *	weight,
		SimdBool *	internal,
		const float *const *	bias,
		const float *const *	params
	)

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

Parameters

[in,out]	context	- a pointer to FP32 merged convolution context. It must be created by function SimdSynetMergedConvolution32fInit and released by function SimdRelease.
[in]	weight	- a pointer to the array with pointers to convolution weights. The array size is determined by number of merged convolutions.
[out]	internal	- a ponter to the array of flags signalized that weights are stored in the internal buffer. The array size is determined by number of merged convolutions. Can be NULL.
[in]	bias	- a pointer to the array with pointers to bias. The array size is determined by number of merged convolutions. Can be NULL.
[in]	params	- a pointer to the array with pointers to parameters of the activation functions (see SimdConvolutionActivationType). The array size is determined by number of merged convolutions. Can be NULL.

SimdSynetMergedConvolution32fForward()

void SimdSynetMergedConvolution32fForward	(	void *	context,
		const float *	src,
		float *	buf,
		float *	dst
	)

Performs forward propagation of FP32 merged convolution algorithm.

Parameters

[in]	context	- a pointer to FP32 merged convolution context. It must be created by function SimdSynetMergedConvolution32fInit and released by function SimdRelease.
[in]	src	- a pointer to input image.
[out]	buf	- a pointer to external temporary buffer. The size of the external temporary buffer is determined by function SimdSynetMergedConvolution32fExternalBufferSize. Can be NULL (it causes usage of internal buffer).
[out]	dst	- a pointer to output image.
