DSPLIB_lud_inv_init_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_lud_inv_init_ci	(	DSPLIB_kernelHandle	handle,
		const DSPLIB_bufParams2D_t *	bufParamsP,
		const DSPLIB_bufParams2D_t *	bufParamsL,
		const DSPLIB_bufParams2D_t *	bufParamsU,
		const DSPLIB_bufParams2D_t *	bufParamsinvA,
		const DSPLIB_lud_invInitArgs *	pKerInitArgs
	)

This function is the initialization function for the C7x implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_lud_inv_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_lud_inv_exec_ci would be called later independently by the application. When DSPLIB_lud_inv_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_lud_inv_exec_ci does not lose cycles to determine the hardware configuration.

Parameters

[in]	handle	: Active handle to the kernel
[in]	bufParamsP	: Pointer to the structure containing dimensional information of input buffer P
[in]	bufParamsL	: Pointer to the structure containing dimensional information of input buffer L
[in]	bufParamsU	: Pointer to the structure containing dimensional information of input buffer U
[out]	bufParamsinvA	: Pointer to the structure containing dimensional information of ouput buffer invA
[in]	pKerInitArgs	: Pointer to the structure holding init parameters

Returns

Status value indicating success or failure. Refer to DSPLIB_STATUS.

DSPLIB_STATUS DSPLIB_lud_inv_exec_ci	(	DSPLIB_kernelHandle	handle,
		void *restrict	pP,

		void *restrict	pU,
		void *restrict	pinvA,
		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_lud_inv_exec.

The function uses streaming engine to load data in TRANSPOSE MODE. The result is then stored at separate location using a streaming address generator.

Parameters

[in]	handle	: Active handle to the kernel
[in]	pP	: Pointer to permutation matrix P
[in]	pL	: Pointer to lower triangular matrix L
[in]	pU	: Pointer to upper triangular matrix U
[out]	pinvA	: Pointer to inverse of A matrix
[in]	pScratch	: Pointer to scratch buffer

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
