Function Documentation

DSPLIB_sqrAdd_init_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_sqrAdd_init_ci	(	DSPLIB_kernelHandle	handle,
		const DSPLIB_bufParams1D_t *	bufParamsIn,
		const DSPLIB_bufParams1D_t *	bufParamsOut,
		const DSPLIB_sqrAdd_InitArgs *	pKerInitArgs
	)

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_sqrAdd_init.

This function determines the configuration for the streaming engine resources based on the function call parameters, and the configuration is saved in bufPBlock array. In the kernel call sequence, DSPLIB_sqrAdd_exec_ci would be called later independently by the application. When DSPLIB_sqrAdd_exec_ci runs, it merely retrieves the configuration from the bufPBlock and uses it to set up the hardware resources. This arrangement is so that DSPLIB_sqrAdd_exec_ci does not lose cycles to determine the hardware configuration.

Parameters

[in]	handle	: Active handle to the kernel
[in]	bufParamsIn	: Pointer to the structure containing dimensional information of input buffer
[out]	bufParamsOut	: Pointer to the structure containing dimensional information of ouput buffer
[in]	pKerInitArgs	: Pointer to the structure holding init parameters

Returns

Status value indicating success or failure. Refer to DSPLIB_STATUS.

DSPLIB_sqrAdd_exec_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_sqrAdd_exec_ci	(	DSPLIB_kernelHandle	handle,
		void *restrict	pIn,
		void *restrict	pOut
	)

This function is the main execution function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_sqrAdd_exec.

The function uses MMA hardware accelerator to perform the convolution computation. Filter data is loaded into B panel of the MMA from memory using one streaming engine, while the input data is loaded into A vectors of the MMA using the other streaming engine. Result of the compute from MMA C panel is stored into memory using a stream sqrAddress generator.

Parameters

[in]	handle	: Active handle to the kernel
[in]	pIn	: Pointer to buffer holding the input data
[out]	pOut	: Pointer to buffer holding the output data

Returns

Status value indicating success or failure. Refer to DSPLIB_STATUS.

Performance Considerations:

For best performance,

• the input and output data buffers are expected to be in L2 memory
• the buffer pointers are assumed to be 64-byte aligned
