Function Documentation

◆ DSPLIB_svd_init_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_svd_init_ci	(	DSPLIB_kernelHandle	handle,
		const DSPLIB_bufParams2D_t *	bufParamsIn,
		const DSPLIB_bufParams2D_t *	bufParamsU,
		const DSPLIB_bufParams2D_t *	bufParamsV,
		const DSPLIB_bufParams1D_t *	bufParamsDiag,
		const DSPLIB_bufParams1D_t *	bufParamsSuperDiag,
		const DSPLIB_svdInitArgs *	pKerInitArgs
	)

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_svd_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_svd_exec_ci would be called later independently by the application. When DSPLIB_svd_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_svd_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]	bufParamsU	: Pointer to the structure containing dimensional information of output buffer U
[out]	bufParamsV	: Pointer to the structure containing dimensional information of output buffer V
[out]	bufParamsDiag	: Pointer to the structure containing dimensional information of output buffer Diag
[out]	bufParamsSuperDiag	: Pointer to the structure containing dimensional information of output buffer SuperDiag
[in]	pKerInitArgs	: Pointer to the structure holding init parameters

Returns: Status value indicating success or failure. Refer to DSPLIB_STATUS.

Definition at line 64 of file DSPLIB_svd_ci.cpp.

		void *restrict	pU,
		void *restrict	pV,
		void *restrict	pDiag,
		void *restrict	pSuperDiag,
		void *restrict	pU1,
		void *restrict	pV1,
		void *restrict	pScratch
	)

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

Parameters

[in]	handle	: Active handle to the kernel
[in]	pA	: Pointer to the input buffer pA
[out]	pU	: Pointer to the output buffer pU
[out]	pV	: Pointer to the output buffer pV
[out]	pDiag	: Pointer to the output buffer pDiag
[out]	pSuperDiag	: Pointer to the output buffer pSuperDiag
[in]	pU1	: Pointer to the buffer pU1
[in]	pV1	: Pointer to the buffer pV1
[out]	pScratch	: Pointer to the buffer pScratch

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

Assumptions:: The arrays A, U, V, Diag, SuperDiag, U1, V1 and Scratch are stored in distinct arrays In-place processing of A is not allowed.
