◆ DSPLIB_qrd_inverse_init_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_qrd_inverse_init_ci	(	DSPLIB_kernelHandle	handle,
		DSPLIB_bufParams2D_t *	bufParamsQ,
		DSPLIB_bufParams2D_t *	bufParamsR,
		DSPLIB_bufParams2D_t *	bufParamsInvA,
		DSPLIB_bufParams2D_t *	bufParamsInvAFinal,
		const DSPLIB_qrdInvInitArgs *	pKerInitArgs
	)

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

Parameters

[in]	handle	: Active handle to the kernel
[in]	bufParamsQ	: Pointer to the structure containing dimensional information of Q matrix
[in]	bufParamsR	: Pointer to the structure containing dimensional information of R matrix
[in]	bufParamsInvA	: Pointer to the structure containing dimensional information of A inverse buffer matrix
[out]	bufParamsInvAFinal	: Pointer to the structure containing dimensional information of final A inverse matrix.
[in]	pKerInitArgs	: Pointer to the structure holding init parameters

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

◆ DSPLIB_qrd_inverse_exec_ci()

template<typename dataType >

DSPLIB_STATUS DSPLIB_qrd_inverse_exec_ci	(	DSPLIB_kernelHandle	handle,
		void *restrict	pQ,
		void *restrict	pR,
		void *restrict	pInvA,
		void *restrict	pInvAScratch,
		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_qrd_inverse_exec.

The function implements the optimized code for computing inverse of input matrix A.

Parameters

[in]	handle	: Active handle to the kernel
[in]	pQ	: Pointer to matrix Q[NRows*NRows]
[in]	pR	: Pointer to upper triangular matrix R[NRows*NCols]
[in]	pInvA	: Pointer to A inverse buffer matrix
[out]	pInvAScratch	: Pointer to the Scratch Buffer
[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

◆ DSPLIB_qrd_inverse_init_cn()

template<typename dataType >

DSPLIB_STATUS DSPLIB_qrd_inverse_init_cn	(	DSPLIB_kernelHandle	handle,

		DSPLIB_bufParams2D_t *	bufParamsInvA,
		DSPLIB_bufParams2D_t *	bufParamsInvAFinal,
		const DSPLIB_qrdInvInitArgs *	pKerInitArgs
	)

This function is the initialization function for the natural C implementation of the kernel. The function declaration conforms to the declaration of DSPLIB_qrd_inverse_init.

Parameters
