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.

)

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
