Detailed Description

A framework to accelerate FP32 convolution in Synet Framework.

Function Documentation

SimdSynetConvolution32fInit()

void * SimdSynetConvolution32fInit	(	size_t	batch,
		const SimdConvolutionParameters *	conv,
		SimdSynetCompatibilityType	compatibility
	)

Initilizes FP32 convolution algorithm.

Parameters

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

Returns

a pointer to FP32 convolution context. On error it returns NULL. It must be released with using of function SimdRelease. This pointer is used in functions SimdSynetConvolution32fExternalBufferSize, SimdSynetConvolution32fInternalBufferSize, SimdSynetConvolution32fInfo, SimdSynetConvolution32fSetParams and SimdSynetConvolution32fForward.

SimdSynetConvolution32fExternalBufferSize()

size_t SimdSynetConvolution32fExternalBufferSize

(

const void *

context

)

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

Parameters

[in]

context

- a pointer to FP32 convolution context. It must be created by function SimdSynetConvolution32fInit and released by function SimdRelease.

Returns

size of external temporary buffer required for FP32 convolution algorithm.

SimdSynetConvolution32fInternalBufferSize()

size_t SimdSynetConvolution32fInternalBufferSize

(

const void *

context

)

Gets size of internal buffer used inside FP32 convolution algorithm.

Parameters

[in]

context

- a pointer to FP32 convolution context. It must be created by function SimdSynetConvolution32fInit and released by function SimdRelease.

Returns

size of internal buffer used inside FP32 convolution algorithm.

SimdSynetConvolution32fInfo()

const char * SimdSynetConvolution32fInfo

(

const void *

context

)

Gets description of internal implementation of FP32 convolution algorithm.

Parameters

[in]

context

- a pointer to FP32 convolution context. It must be created by function SimdSynetConvolution32fInit and released by function SimdRelease.

Returns

string with description of internal implementation of FP32 convolution algorithm.

SimdSynetConvolution32fSetParams()

void SimdSynetConvolution32fSetParams	(	void *	context,
		const float *	weight,
		SimdBool *	internal,
		const float *	bias,
		const float *	params
	)

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

Parameters

[in,out]	context	- a pointer to FP32 convolution context. It must be created by function SimdSynetConvolution32fInit and released by function SimdRelease.
[in]	weight	- a pointer to convolution 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.

SimdSynetConvolution32fForward()

void SimdSynetConvolution32fForward	(	void *	context,
		const float *	src,
		float *	buf,
		float *	dst
	)

Performs forward propagation of FP32 convolution algorithm.

Parameters

[in]	context	- a pointer to FP32 convolution context. It must be created by function SimdSynetConvolution32fInit 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 SimdSynetConvolution32fExternalBufferSize. Can be NULL (it causes usage of internal buffer).
[out]	dst	- a pointer to output tensor.
